@@ -11,71 +16,125 @@ Scality’s Open Source Multi-Cloud Data Controller.
 CloudServer provides a single AWS S3 API interface to access multiple
 backend data storage both on-premise or public in the cloud.
 
-This repository contains a fork of CloudServer with [Vitastor](https://git.yourcmc.ru/vitalif/vitastor)
-backend support.
+CloudServer is useful for Developers, either to run as part of a
+continous integration test environment to emulate the AWS S3 service locally
+or as an abstraction layer to develop object storage enabled
+application on the go.
 
-## Quick Start with Vitastor
+## Learn more at [www.zenko.io/cloudserver](https://www.zenko.io/cloudserver/)
 
-Vitastor Backend is in experimental status, however you can already try to
-run it and write or read something, or even mount it with [GeeseFS](https://github.com/yandex-cloud/geesefs),
-it works too 😊.
+## [May I offer you some lovely documentation?](http://s3-server.readthedocs.io/en/latest/)
 
-Installation instructions:
+## Docker
 
-### Install Vitastor
+[Run your Zenko CloudServer with Docker](https://hub.docker.com/r/scality/s3server/)
 
-Refer to [Vitastor Quick Start Manual](https://git.yourcmc.ru/vitalif/vitastor/src/branch/master/docs/intro/quickstart.en.md).
+## Contributing
 
-### Install Zenko with Vitastor Backend
+In order to contribute, please follow the
+[Contributing Guidelines](
+https://github.com/scality/Guidelines/blob/master/CONTRIBUTING.md).
 
-- Clone this repository: `git clone https://git.yourcmc.ru/vitalif/zenko-cloudserver-vitastor`
-- Install dependencies: `npm install --omit dev` or just `npm install`
-- Clone Vitastor repository: `git clone https://git.yourcmc.ru/vitalif/vitastor`
-- Build Vitastor node.js binding by running `npm install` in `node-binding` subdirectory of Vitastor repository.
-  You need `node-gyp` and `vitastor-client-dev` (Vitastor client library) for it to succeed.
-- Symlink Vitastor module to Zenko: `ln -s /path/to/vitastor/node-binding /path/to/zenko/node_modules/vitastor`
+## Installation
 
-### Install and Configure MongoDB
+### Dependencies
 
-Refer to [MongoDB Manual](https://www.mongodb.com/docs/manual/installation/).
+Building and running the Zenko CloudServer requires node.js 10.x and yarn v1.17.x
+. Up-to-date versions can be found at
+[Nodesource](https://github.com/nodesource/distributions).
 
-### Setup Zenko
+### Clone source code
 
-- Create a separate pool for S3 object data in your Vitastor cluster: `vitastor-cli create-pool s3-data`
-- Retrieve ID of the new pool from `vitastor-cli ls-pools --detail s3-data`
-- In another pool, create an image for storing Vitastor volume metadata: `vitastor-cli create -s 10G s3-volume-meta`
-- Copy `config.json.vitastor` to `config.json`, adjust it to match your domain
-- Copy `authdata.json.example` to `authdata.json` - this is where you set S3 access & secret keys,
-  and also adjust them if you want to. Scality seems to use a separate auth service "Scality Vault" for
-  access keys, but it's not published, so let's use a file for now.
-- Copy `locationConfig.json.vitastor` to `locationConfig.json` - this is where you set Vitastor cluster access data.
-  You should put correct values for `pool_id` (pool ID from the second step) and `metadata_image` (from the third step)
-  in this file.
-
-Note: `locationConfig.json` in this version corresponds to storage classes (like STANDARD, COLD, etc)
-instead of "locations" (zones like us-east-1) as it was in original Zenko CloudServer.
-
-### Start Zenko
-
-Start the S3 server with: `node index.js`
-
-If you use default settings, Zenko CloudServer starts on port 8000.
-The default access key is `accessKey1` with a secret key of `verySecretKey1`.
-
-Now you can access your S3 with `s3cmd` or `geesefs`:
-
-```
-s3cmd --access_key=accessKey1 --secret_key=verySecretKey1 --host=http://localhost:8000 mb s3://testbucket
+```shell
+git clone https://github.com/scality/S3.git
 ```
 
-```
-AWS_ACCESS_KEY_ID=accessKey1 \
-    AWS_SECRET_ACCESS_KEY=verySecretKey1 \
-    geesefs --endpoint http://localhost:8000 testbucket mountdir
+### Install js dependencies
+
+Go to the ./S3 folder,
+
+```shell
+yarn install --frozen-lockfile
 ```

+If you get an error regarding level-down bindings, try clearing your yarn cache:
+
+```shell
+yarn cache clean
+```
+
+## Run it with a file backend
+
+```shell
+yarn start
+```
+
+This starts a Zenko CloudServer on port 8000. Two additional ports 9990 and
+9991 are also open locally for internal transfer of metadata and data,
+respectively.
+
+The default access key is accessKey1 with
+a secret key of verySecretKey1.
+
+By default the metadata files will be saved in the
+localMetadata directory and the data files will be saved
+in the localData directory within the ./S3 directory on your
+machine.  These directories have been pre-created within the
+repository.  If you would like to save the data or metadata in
+different locations of your choice, you must specify them with absolute paths.
+So, when starting the server:
+
+```shell
+mkdir -m 700 $(pwd)/myFavoriteDataPath
+mkdir -m 700 $(pwd)/myFavoriteMetadataPath
+export S3DATAPATH="$(pwd)/myFavoriteDataPath"
+export S3METADATAPATH="$(pwd)/myFavoriteMetadataPath"
+yarn start
+```
+
+## Run it with multiple data backends
+
+```shell
+export S3DATA='multiple'
+yarn start
+```
+
+This starts a Zenko CloudServer on port 8000.
+The default access key is accessKey1 with
+a secret key of verySecretKey1.
+
+With multiple backends, you have the ability to
+choose where each object will be saved by setting
+the following header with a locationConstraint on
+a PUT request:
+
+```shell
+'x-amz-meta-scal-location-constraint':'myLocationConstraint'
+```
+
+If no header is sent with a PUT object request, the
+location constraint of the bucket will determine
+where the data is saved. If the bucket has no location
+constraint, the endpoint of the PUT request will be
+used to determine location.
+
+See the Configuration section below to learn how to set
+location constraints.
+
+## Run it with an in-memory backend
+
+```shell
+yarn run mem_backend
+```
+
+This starts a Zenko CloudServer on port 8000.
+The default access key is accessKey1 with
+a secret key of verySecretKey1.

-
-Running CloudServer with a File Backend
----------------------------------------
-
-.. code-block:: shell
-
-   $ yarn start
-
-This starts a Zenko CloudServer on port 8000. Two additional ports, 9990 
-and 9991, are also open locally for internal transfer of metadata and 
-data, respectively.
-
-The default access key is accessKey1. The secret key is verySecretKey1.
-
-By default, metadata files are saved in the localMetadata directory and 
-data files are saved in the localData directory in the local ./cloudserver 
-directory. These directories are pre-created within the repository. To 
-save data or metadata in different locations, you must specify them using 
-absolute paths. Thus, when starting the server:
-
-.. code-block:: shell
-
-   $ mkdir -m 700 $(pwd)/myFavoriteDataPath
-   $ mkdir -m 700 $(pwd)/myFavoriteMetadataPath
-   $ export S3DATAPATH="$(pwd)/myFavoriteDataPath"
-   $ export S3METADATAPATH="$(pwd)/myFavoriteMetadataPath"
-   $ yarn start
-
-Running CloudServer with Multiple Data Backends
------------------------------------------------
-
-.. code-block:: shell
-
-   $ export S3DATA='multiple'
-   $ yarn start
-
-This starts a Zenko CloudServer on port 8000. 
-
-The default access key is accessKey1. The secret key is verySecretKey1.
-
-With multiple backends, you can choose where each object is saved by setting
-the following header with a location constraint in a PUT request:
-
-.. code-block:: shell
-
-    'x-amz-meta-scal-location-constraint':'myLocationConstraint'
-
-If no header is sent with a PUT object request, the bucket’s location
-constraint determines where the data is saved. If the bucket has no
-location constraint, the endpoint of the PUT request determines location.
-
-See the Configuration_ section to set location constraints.
-
-Run CloudServer with an In-Memory Backend
------------------------------------------
-
-.. code-block:: shell
-
-   $ yarn run mem_backend
-
-This starts a Zenko CloudServer on port 8000. 
-
-The default access key is accessKey1. The secret key is verySecretKey1.

+Scality with SSL
+~~~~~~~~~~~~~~~~~~~~~~
 
-To use https with your local CloudServer, you must set up
-SSL certificates. 
+If you wish to use https with your local Zenko CloudServer, you need to set up
+SSL certificates. Here is a simple guide of how to do it.
 
-1. Deploy CloudServer using `our DockerHub page
-   <https://hub.docker.com/r/zenko/cloudserver/>`__ (run it with a file
-   backend).
+Deploying Zenko CloudServer
+^^^^^^^^^^^^^^^^^^^
 
-   .. Note:: If Docker is not installed locally, follow the
-      `instructions to install it for your distribution 
-      <https://docs.docker.com/engine/installation/>`__
+First, you need to deploy **Zenko CloudServer**. This can be done very easily
+via `our **DockerHub**
+page <https://hub.docker.com/r/scality/s3server/>`__ (you want to run it
+with a file backend).
 
-2. Update the CloudServer container’s config 
+    *Note:* *- If you don't have docker installed on your machine, here
+    are the `instructions to install it for your
+    distribution <https://docs.docker.com/engine/installation/>`__*
 
-   Add your certificates to your container. To do this, 
-   #. exec inside the CloudServer container. 
+Updating your Zenko CloudServer container's config
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
 
-   #. Run ``$> docker ps`` to find the container’s ID (the corresponding 
-      image name is ``scality/cloudserver``.

-   #. Copy the corresponding container ID (``894aee038c5e`` in the present
-      example), and run:

-   For both distributions:
-
-   #. Choose where shared data and metadata from the local
-      `CloudServer <http://www.zenko.io/cloudserver/>`__ shall be stored (The
-      present example uses /var/nfs/data and /var/nfs/metadata). Set permissions
-      for these folders for
-      sharing over NFS:
-
-      .. code:: sh
-
-        $> mkdir -p /var/nfs/data /var/nfs/metadata
-        $> chmod -R 777 /var/nfs/
-
-   #. The /etc/exports file configures network permissions and r-w-x permissions
-      for NFS access. Edit /etc/exports, adding the following lines:
-
-      .. code:: sh
-
-        /var/nfs/data        10.200.15.96(rw,sync,no_root_squash) 10.200.15.97(rw,sync,no_root_squash)
-        /var/nfs/metadata    10.200.15.96(rw,sync,no_root_squash) 10.200.15.97(rw,sync,no_root_squash)
-
-      Ubuntu applies the no\_subtree\_check option by default, so both
-      folders are declared with the same permissions, even though they’re in
-      the same tree.
-
-   #. Export this new NFS table:
-
-      .. code:: sh
-
-        $> sudo exportfs -a
-
-   #. Edit the ``MountFlags`` option in the Docker config in
-      /lib/systemd/system/docker.service to enable NFS mount from Docker volumes
-      on other machines:
-
-      .. code:: sh
-
-        MountFlags=shared
-
-   #. Restart the NFS server and Docker daemons to apply these changes.
-
-      * On Ubuntu 14.04
-
-        .. code:: sh

-         $> sudo systemctl daemon-reload
-         $> sudo systemctl restart docker
-
-
-4. Set Up a Docker Swarm
-
-  * On all machines and distributions:
-
-    Set up the Docker volumes to be mounted to the NFS server for CloudServer’s
-    data and metadata storage. The following commands must be replicated on all
-    machines:
-
-    .. code:: sh
-
-     $> docker volume create --driver local --opt type=nfs --opt o=addr=10.200.15.113,rw --opt device=:/var/nfs/data --name data
-     $> docker volume create --driver local --opt type=nfs --opt o=addr=10.200.15.113,rw --opt device=:/var/nfs/metadata --name metadata
-
-    There is no need to ``docker exec`` these volumes to mount them: the
-    Docker Swarm manager does this when the Docker service is started.
-
-  * On a server:
-
-    To start a Docker service on a Docker Swarm cluster, initialize the cluster
-    (that is, define a manager), prompt workers/nodes to join in, and then start
-    the service.
-
-    Initialize the swarm cluster, and review its response:
-
-    .. code:: sh
-
-      $> docker swarm init --advertise-addr 10.200.15.113
-
-      Swarm initialized: current node (db2aqfu3bzfzzs9b1kfeaglmq) is now a manager.
-
-      To add a worker to this swarm, run the following command:

+
+Configure NFS
+-------------
+
+On Clients
+~~~~~~~~~~
+
+Your NFS Clients will mount Docker volumes over your NFS Server's shared
+folders. Hence, you don't have to mount anything manually, you just have
+to install the NFS commons:
+
+On Ubuntu 14.04
+^^^^^^^^^^^^^^^
+
+Simply install the NFS commons:
+
+.. code:: sh
+
+    $> sudo apt-get install nfs-common
+
+On CentOS 7
+^^^^^^^^^^^
+
+Install the NFS utils, and then start the required services:
+
+.. code:: sh
+
+    $> yum install nfs-utils
+    $> sudo systemctl enable rpcbind
+    $> sudo systemctl enable nfs-server
+    $> sudo systemctl enable nfs-lock
+    $> sudo systemctl enable nfs-idmap
+    $> sudo systemctl start rpcbind
+    $> sudo systemctl start nfs-server
+    $> sudo systemctl start nfs-lock
+    $> sudo systemctl start nfs-idmap
+
+On Server
+~~~~~~~~~
+
+Your NFS Server will be the machine to physically host the data and
+metadata. The package(s) we will install on it is slightly different
+from the one we installed on the clients.
+
+On Ubuntu 14.04
+^^^^^^^^^^^^^^^
+
+Install the NFS server specific package and the NFS commons:
+
+.. code:: sh
+
+    $> sudo apt-get install nfs-kernel-server nfs-common
+
+On CentOS 7
+^^^^^^^^^^^
+
+Same steps as with the client: install the NFS utils and start the
+required services:
+
+.. code:: sh
+
+    $> yum install nfs-utils
+    $> sudo systemctl enable rpcbind
+    $> sudo systemctl enable nfs-server
+    $> sudo systemctl enable nfs-lock
+    $> sudo systemctl enable nfs-idmap
+    $> sudo systemctl start rpcbind
+    $> sudo systemctl start nfs-server
+    $> sudo systemctl start nfs-lock
+    $> sudo systemctl start nfs-idmap
+
+On Ubuntu 14.04 and CentOS 7
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Choose where your shared data and metadata from your local `Zenko CloudServer
+<http://www.zenko.io/cloudserver/>`__ will be stored.
+We chose to go with /var/nfs/data and /var/nfs/metadata. You also need
+to set proper sharing permissions for these folders as they'll be shared
+over NFS:
+
+.. code:: sh
+
+    $> mkdir -p /var/nfs/data /var/nfs/metadata
+    $> chmod -R 777 /var/nfs/
+
+Now you need to update your **/etc/exports** file. This is the file that
+configures network permissions and rwx permissions for NFS access. By
+default, Ubuntu applies the no\_subtree\_check option, so we declared
+both folders with the same permissions, even though they're in the same
+tree:
+
+.. code:: sh
+
+    $> sudo vim /etc/exports
+
+In this file, add the following lines:
+
+.. code:: sh
+
+    /var/nfs/data        10.200.15.96(rw,sync,no_root_squash) 10.200.15.97(rw,sync,no_root_squash)
+    /var/nfs/metadata    10.200.15.96(rw,sync,no_root_squash) 10.200.15.97(rw,sync,no_root_squash)
+
+Export this new NFS table:
+
+.. code:: sh
+
+    $> sudo exportfs -a
+
+Eventually, you need to allow for NFS mount from Docker volumes on other
+machines. You need to change the Docker config in
+**/lib/systemd/system/docker.service**:
+
+.. code:: sh
+
+    $> sudo vim /lib/systemd/system/docker.service
+
+In this file, change the **MountFlags** option:
+
+.. code:: sh
+
+    MountFlags=shared
+
+Now you just need to restart the NFS server and docker daemons so your
+changes apply.
+
+On Ubuntu 14.04
+^^^^^^^^^^^^^^^
+
+Restart your NFS Server and docker services:
+
+.. code:: sh
+
+    $> sudo service nfs-kernel-server restart
+    $> sudo service docker restart
+
+On CentOS 7
+^^^^^^^^^^^
+
+Restart your NFS Server and docker daemons:
+
+.. code:: sh
+
+    $> sudo systemctl restart nfs-server
+    $> sudo systemctl daemon-reload
+    $> sudo systemctl restart docker
+
+Set up your Docker Swarm service
+--------------------------------
+
+On All Machines
+~~~~~~~~~~~~~~~
+
+On Ubuntu 14.04 and CentOS 7
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+We will now set up the Docker volumes that will be mounted to the NFS
+Server and serve as data and metadata storage for Zenko CloudServer. These two
+commands have to be replicated on all machines:
+
+.. code:: sh
+
+    $> docker volume create --driver local --opt type=nfs --opt o=addr=10.200.15.113,rw --opt device=:/var/nfs/data --name data
+    $> docker volume create --driver local --opt type=nfs --opt o=addr=10.200.15.113,rw --opt device=:/var/nfs/metadata --name metadata
+
+There is no need to ""docker exec" these volumes to mount them: the
+Docker Swarm manager will do it when the Docker service will be started.
+
+On Server
+^^^^^^^^^
+
+To start a Docker service on a Docker Swarm cluster, you first have to
+initialize that cluster (i.e.: define a manager), then have the
+workers/nodes join in, and then start the service. Initialize the swarm
+cluster, and look at the response:
+
+.. code:: sh
+
+    $> docker swarm init --advertise-addr 10.200.15.113
+
+    Swarm initialized: current node (db2aqfu3bzfzzs9b1kfeaglmq) is now a manager.
+
+    To add a worker to this swarm, run the following command:
+
+        docker swarm join \
+        --token SWMTKN-1-5yxxencrdoelr7mpltljn325uz4v6fe1gojl14lzceij3nujzu-2vfs9u6ipgcq35r90xws3stka \
+        10.200.15.113:2377
+
+    To add a manager to this swarm, run 'docker swarm join-token manager' and follow the instructions.
+
+On Clients
+^^^^^^^^^^
+
+Simply copy/paste the command provided by your docker swarm init. When
+all goes well, you'll get something like this:
+
+.. code:: sh
+
+    $> docker swarm join --token SWMTKN-1-5yxxencrdoelr7mpltljn325uz4v6fe1gojl14lzceij3nujzu-2vfs9u6ipgcq35r90xws3stka 10.200.15.113:2377
+
+    This node joined a swarm as a worker.
+
+On Server
+^^^^^^^^^
+
+Start the service on your swarm cluster!
+
+.. code:: sh
+
+    $> docker service create --name s3 --replicas 1 --mount type=volume,source=data,target=/usr/src/app/localData --mount type=volume,source=metadata,target=/usr/src/app/localMetadata -p 8000:8000 scality/s3server
+
+If you run a docker service ls, you should have the following output:
 
 .. code:: sh
 
     $> docker service ls
     ID            NAME  MODE        REPLICAS  IMAGE
-    ocmggza412ft  s3    replicated  1/1       scality/cloudserver:latest
+    ocmggza412ft  s3    replicated  1/1       scality/s3server:latest
 
-If the service does not start, consider disabling apparmor/SELinux.
+If your service won't start, consider disabling apparmor/SELinux.
 
-Testing the High-Availability CloudServer
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Testing your High Availability S3Server
+---------------------------------------
 
-On all machines (client/server) and distributions (Ubuntu and CentOS),
-determine where CloudServer is running using ``docker ps``. CloudServer can
-operate on any node of the Swarm cluster, manager or worker. When you find
-it, you can kill it with ``docker stop <container id>``. It will respawn
-on a different node. Now, if one server falls, or if Docker stops
-unexpectedly, the end user will still be able to access your the local CloudServer.
-
-Troubleshooting
+On All Machines
 ~~~~~~~~~~~~~~~
 
-To troubleshoot the service, run:
+On Ubuntu 14.04 and CentOS 7
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Try to find out where your Scality Zenko CloudServer is actually running using
+the **docker ps** command. It can be on any node of the swarm cluster,
+manager or worker. When you find it, you can kill it, with **docker stop

+It is available both on Debian and RedHat distributions. For this
+tutorial, we used an Ubuntu 14.04 host to deploy and use s3fs over
+Scality's Zenko CloudServer.
 
 Deploying Zenko CloudServer with SSL
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+----------------------------
 
-First, deploy CloudServer with a file backend using `our DockerHub page
-<https://hub.docker.com/r/zenko/cloudserver>`__.
+First, you need to deploy **Zenko CloudServer**. This can be done very easily
+via `our DockerHub
+page <https://hub.docker.com/r/scality/s3server/>`__ (you want to run it
+with a file backend).
 
-.. note::
+    *Note:* *- If you don't have docker installed on your machine, here
+    are the `instructions to install it for your
+    distribution <https://docs.docker.com/engine/installation/>`__*
 
-  If Docker is not installed on your machine, follow
-  `these instructions <https://docs.docker.com/engine/installation/>`__
-  to install it for your distribution.
+You also necessarily have to set up SSL with Zenko CloudServer to use s3fs. We
+have a nice
+`tutorial <https://s3.scality.com/v1.0/page/scality-with-ssl>`__ to help
+you do it.
 
-You must also set up SSL with CloudServer to use s3fs. See `Using SSL
-<./GETTING_STARTED#Using_SSL>`__ for instructions.
-
-s3fs Setup
-~~~~~~~~~~
+s3fs setup
+----------
 
 Installing s3fs
----------------
+~~~~~~~~~~~~~~~
 
-Follow the instructions in the s3fs `README
-<https://github.com/s3fs-fuse/s3fs-fuse/blob/master/README.md#installation-from-pre-built-packages>`__,
-
-Check that s3fs is properly installed. A version check should return
-a response resembling:
+s3fs has quite a few dependencies. As explained in their
+`README <https://github.com/s3fs-fuse/s3fs-fuse/blob/master/README.md#installation>`__,
+the following commands should install everything for Ubuntu 14.04:
 
 .. code:: sh
 
-    $> s3fs --version
+    $> sudo apt-get install automake autotools-dev g++ git libcurl4-gnutls-dev
+    $> sudo apt-get install libfuse-dev libssl-dev libxml2-dev make pkg-config
+
+Now you want to install s3fs per se:
+
+.. code:: sh
+
+    $> git clone https://github.com/s3fs-fuse/s3fs-fuse.git
+    $> cd s3fs-fuse
+    $> ./autogen.sh
+    $> ./configure
+    $> make
+    $> sudo make install
+
+Check that s3fs is properly installed by checking its version. it should
+answer as below:
+
+.. code:: sh
+
+     $> s3fs --version

 Configuring s3fs
-----------------
+~~~~~~~~~~~~~~~~
 
 s3fs expects you to provide it with a password file. Our file is
 ``/etc/passwd-s3fs``. The structure for this file is
-``ACCESSKEYID:SECRETKEYID``, so, for CloudServer, you can run:
+``ACCESSKEYID:SECRETKEYID``, so, for S3Server, you can run:
 
 .. code:: sh
 
     $> echo 'accessKey1:verySecretKey1' > /etc/passwd-s3fs
     $> chmod 600 /etc/passwd-s3fs
 
-Using CloudServer with s3fs
----------------------------
+Using Zenko CloudServer with s3fs
+------------------------
 
-1. Use /mnt/tests3fs as a mount point.
+First, you're going to need a mountpoint; we chose ``/mnt/tests3fs``:
 
-   .. code:: sh
+.. code:: sh
 
     $> mkdir /mnt/tests3fs
 
-2. Create a bucket on your local CloudServer. In the present example it is
-   named “tests3fs”.
+Then, you want to create a bucket on your local Zenko CloudServer; we named it
+``tests3fs``:
 
-   .. code:: sh
+.. code:: sh
 
     $> s3cmd mb s3://tests3fs
 
-3. Mount the bucket to your mount point with s3fs:
+    *Note:* *- If you've never used s3cmd with our Zenko CloudServer, our README
+    provides you with a `recommended
+    config <https://github.com/scality/S3/blob/master/README.md#s3cmd>`__*
 
-   .. code:: sh
+Now you can mount your bucket to your mountpoint with s3fs:
+
+.. code:: sh
 
     $> s3fs tests3fs /mnt/tests3fs -o passwd_file=/etc/passwd-s3fs -o url="https://s3.scality.test:8000/" -o use_path_request_style
 
-   The structure of this command is:
-   ``s3fs BUCKET_NAME PATH/TO/MOUNTPOINT -o OPTIONS``. Of these mandatory
-   options:
+    *If you're curious, the structure of this command is*
+    ``s3fs BUCKET_NAME PATH/TO/MOUNTPOINT -o OPTIONS``\ *, and the
+    options are mandatory and serve the following purposes:
+    * ``passwd_file``\ *: specifiy path to password file;
+    * ``url``\ *: specify the hostname used by your SSL provider;
+    * ``use_path_request_style``\ *: force path style (by default, s3fs
+    uses subdomains (DNS style)).*
 
-   * ``passwd_file`` specifies the path to the password file.
-   * ``url`` specifies the host name used by your SSL provider.
-   * ``use_path_request_style`` forces the path style (by default,
-       s3fs uses DNS-style subdomains).
+| From now on, you can either add files to your mountpoint, or add
+  objects to your bucket, and they'll show in the other.
+| For example, let's' create two files, and then a directory with a file
+  in our mountpoint:
 
-Once the bucket is mounted, files added to the mount point or
-objects added to the bucket will appear in both locations.
+.. code:: sh
 
-Example
--------
+    $> touch /mnt/tests3fs/file1 /mnt/tests3fs/file2
+    $> mkdir /mnt/tests3fs/dir1
+    $> touch /mnt/tests3fs/dir1/file3
 
-   Create two files, and then a directory with a file in our mount point:
+Now, I can use s3cmd to show me what is actually in S3Server:
 
-   .. code:: sh
+.. code:: sh
 
-      $> touch /mnt/tests3fs/file1 /mnt/tests3fs/file2
-      $> mkdir /mnt/tests3fs/dir1
-      $> touch /mnt/tests3fs/dir1/file3
+    $> s3cmd ls -r s3://tests3fs
 
-   Now, use s3cmd to show what is in CloudServer:
+    2017-02-28 17:28         0   s3://tests3fs/dir1/
+    2017-02-28 17:29         0   s3://tests3fs/dir1/file3
+    2017-02-28 17:28         0   s3://tests3fs/file1
+    2017-02-28 17:28         0   s3://tests3fs/file2
 
-   .. code:: sh
-
-      $> s3cmd ls -r s3://tests3fs
-
-      2017-02-28 17:28         0   s3://tests3fs/dir1/
-      2017-02-28 17:29         0   s3://tests3fs/dir1/file3
-      2017-02-28 17:28         0   s3://tests3fs/file1
-      2017-02-28 17:28         0   s3://tests3fs/file2
-
-   Now you can enjoy a filesystem view on your local CloudServer.

-Metadata Search Documentation
-=============================
-
-Description
------------
-
-This feature enables metadata search to be performed on the metadata of objects
-stored in Zenko.
-
-Requirements
-------------
-
-* MongoDB
-
-Design
-------
-
-The Metadata Search feature expands on the existing :code:`GET Bucket` S3 API by
-enabling users to conduct metadata searches by adding the custom Zenko query
-string parameter, :code:`search`. The :code:`search` parameter is structured as a pseudo
-SQL WHERE clause, and supports basic SQL operators. For example:
-:code:`"A=1 AND B=2 OR C=3"` (complex queries can be built using nesting
-operators, :code:`(` and :code:`)`).
-
-The search process is as follows:
-
-* Zenko receives a :code:`GET` request.
-
-  .. code::
-
-    # regular getBucket request
-    GET /bucketname HTTP/1.1
-    Host: 127.0.0.1:8000
-    Date: Wed, 18 Oct 2018 17:50:00 GMT
-    Authorization: authorization string
-
-    # getBucket versions request
-    GET /bucketname?versions HTTP/1.1
-    Host: 127.0.0.1:8000
-    Date: Wed, 18 Oct 2018 17:50:00 GMT
-    Authorization: authorization string
-
-    # search getBucket request
-    GET /bucketname?search=key%3Dsearch-item HTTP/1.1
-    Host: 127.0.0.1:8000
-    Date: Wed, 18 Oct 2018 17:50:00 GMT
-    Authorization: authorization string
-
-* If the request does *not* contain the :code:`search` query parameter, Zenko performs
-  a normal bucket listing and returns an XML result containing the list of
-  objects.
-* If the request *does* contain the :code:`search` query parameter, Zenko parses and
-  validates the search string.
-
-  - If the search string is invalid, Zenko returns an :code:`InvalidArgument` error.
-
-    .. code::
-
-      <?xml version=\"1.0\" encoding=\"UTF-8\"?>
-      <Error>
-        <Code>InvalidArgument</Code>
-        <Message>Invalid sql where clause sent as search query</Message>
-        <Resource></Resource>
-        <RequestId>d1d6afc64345a8e1198e</RequestId>
-      </Error>
-
-  - If the search string is valid, Zenko parses it and generates an abstract
-    syntax tree (AST). The AST is then passed to the MongoDB backend to be
-    used as the query filter for retrieving objects from a bucket that
-    satisfies the requested search conditions. Zenko parses the filtered
-    results and returns them as the response.
-
-Metadata search results have the same structure as a :code:`GET Bucket` response:
-
-.. code:: xml
-
-  <?xml version="1.0" encoding="UTF-8"?>
-  <ListBucketResult xmlns="http://s3.amazonaws.com/doc/2006-03-01/">
-      <Name>bucketname</Name>
-      <Prefix/>
-      <Marker/>
-      <MaxKeys>1000</MaxKeys>
-      <IsTruncated>false</IsTruncated>
-      <Contents>
-          <Key>objectKey</Key>
-          <LastModified>2018-04-19T18:31:49.426Z</LastModified>
-          <ETag>&quot;d41d8cd98f00b204e9800998ecf8427e&quot;</ETag>

-Performing Metadata Searches with Zenko
----------------------------------------
-
-You can perform metadata searches by:
-
-+ Using the :code:`search_bucket` tool in the
-  `Scality/S3 <https://github.com/scality/S3>`_ GitHub repository.
-+ Creating a signed HTTP request to Zenko in your preferred programming
-  language.
-
-Using the S3 Tool
-+++++++++++++++++
-
-After cloning the `Scality/S3 <https://github.com/scality/S3>`_ GitHub repository
-and installing the necessary dependencies, run the following command in the S3
-project’s root directory to access the search tool:
-
-.. code::
-
-  node bin/search_bucket
-
-This generates the following output:
-
-.. code::
-
-    Usage: search_bucket [options]
-
-    Options:
-
-      -V, --version                 output the version number
-      -a, --access-key <accessKey>  Access key id
-      -k, --secret-key <secretKey>  Secret access key
-      -b, --bucket <bucket>         Name of the bucket
-      -q, --query <query>           Search query
-      -h, --host <host>             Host of the server
-      -p, --port <port>             Port of the server
-      -s                            --ssl
-      -v, --verbose
-      -h, --help                    output usage information
-
-In the following examples, Zenko Server is accessible on endpoint
-:code:`http://127.0.0.1:8000` and contains the bucket :code:`zenkobucket`.
-
-.. code::
-
-    # search for objects with metadata "blue"
-    node bin/search_bucket -a accessKey1 -k verySecretKey1 -b zenkobucket \
-        -q "x-amz-meta-color=blue" -h 127.0.0.1 -p 8000
-
-    # search for objects tagged with "type=color"
-    node bin/search_bucket -a accessKey1 -k verySecretKey1 -b zenkobucket \
-        -q "tags.type=color" -h 127.0.0.1 -p 8000
-
-Coding Examples
-+++++++++++++++
-
-Search requests can be also performed by making HTTP requests authenticated
-with one of the AWS Signature schemes: version 2 or version 4. \
-For more about authentication scheme, see:
-
-* https://docs.aws.amazon.com/general/latest/gr/signature-version-2.html
-* http://docs.aws.amazon.com/general/latest/gr/sigv4_signing.html
-* http://docs.aws.amazon.com/general/latest/gr/sigv4-signed-request-examples.html
-
-You can also view examples for making requests with Auth V4 in various
-languages `here <../../../examples>`__.
-
-Specifying Metadata Fields
-~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-To search system metadata headers:
-
-.. code::
-
-    {system-metadata-key}{supported SQL op}{search value}
-    # example
-    key = blueObject
-    size > 0
-    key LIKE "blue.*"
-
-To search custom user metadata:
-
-.. code::
-
-    # metadata must be prefixed with "x-amz-meta-"
-    x-amz-meta-{user-metadata-key}{supported SQL op}{search value}
-
-    # example
-    x-amz-meta-color = blue
-    x-amz-meta-color != red
-    x-amz-meta-color LIKE "b.*"
-
-To search tags:
-
-.. code::
-
-    # tag searches must be prefixed with "tags."
-    tags.{tag-key}{supported SQL op}{search value}
-    # example
-    tags.type = color
-
-Examples queries:
-
-.. code::
-
-    # searching for objects with custom metadata "color"=blue" and are tagged
-    # "type"="color"
-
-    tags.type="color" AND  x-amz-meta-color="blue"
-
-    # searching for objects with the object key containing the substring "blue"
-    # or (custom metadata "color"=blue" and are tagged "type"="color")
-
-    key LIKE '.*blue.*' OR (x-amz-meta-color="blue" AND tags.type="color")
-
-Differences from SQL
-++++++++++++++++++++
-
-Zenko metadata search queries are similar to SQL-query :code:`WHERE` clauses, but
-differ in that:
-
-* They follow the :code:`PCRE` format
-* They do not require values with hyphens to be enclosed in
-  backticks, :code:``(`)``
-
-  .. code::
-
-        # SQL query
-        `x-amz-meta-search-item` = `ice-cream-cone`
-
-        # MD Search query
-        x-amz-meta-search-item = ice-cream-cone
-
-* Search queries do not support all SQL operators.
-
-  .. code::
-
-    # Supported SQL operators:
-    =, <, >, <=, >=, !=, AND, OR, LIKE, <>
-
-    # Unsupported SQL operators:
-    NOT, BETWEEN, IN, IS, +, -, %, ^, /, *, !
-
-Using Regular Expressions in Metadata Search
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Regular expressions in Zenko metadata search differ from SQL in the following
-ways:
-
-+ Wildcards are represented with :code:`.*` instead of :code:`%`.
-+ Regex patterns must be wrapped in quotes. Failure to do this can lead to
-  misinterpretation of patterns.
-+ As with :code:`PCRE`, regular expressions can be entered in either the
-  :code:`/pattern/` syntax or as the pattern itself if regex options are
-  not required.
-
-Example regular expressions:
-
-.. code::
-
-    # search for strings containing word substring "helloworld"
-        ".*helloworld.*"
-        "/.*helloworld.*/"
-        "/.*helloworld.*/i"

-# Cloudserver Release Plan
-
-## Docker Image Generation
-
-Docker images are hosted on [ghcri.io](https://github.com/orgs/scality/packages).
-CloudServer has a few images there:
-
-* Cloudserver container image: ghcr.io/scality/cloudserver
-* Dashboard oras image: ghcr.io/scality/cloudserver/cloudser-dashboard
-* Policies oras image: ghcr.io/scality/cloudserver/cloudser-dashboard
-
-With every CI build, the CI will push images, tagging the
-content with the developer branch's short SHA-1 commit hash.
-This allows those images to be used by developers, CI builds,
-build chain and so on.
-
-Tagged versions of cloudserver will be stored in the production namespace.
-
-## How to Pull Docker Images
-
-```sh
-docker pull ghcr.io/scality/cloudserver:<commit hash>
-docker pull ghcr.io/scality/cloudserver:<tag>
-```
-
-## Release Process
-
-To release a production image:
-
-* Create a PR to bump the package version
-  Update Cloudserver's `package.json` by bumping it to the relevant next
-  version in a new PR. Per example if the last released version was
-  `8.4.7`, the next version would be `8.4.8`.
-
-```js
-{
-  "name": "cloudserver",
-  "version": "8.4.8", <--- Here
-  [...]
-}
-```
-
-* Review & merge the PR
-
-* Create the release on GitHub
-  
-  * Go the Release tab (https://github.com/scality/cloudserver/releases);
-  * Click on the `Draft new release button`;
-  * In the `tag` field, type the name of the release (`8.4.8`), and confirm
-    to create the tag on publish;
-  * Click on `Generate release notes` button to fill the fields;
-  * Rename the release to `Release x.y.z` (e.g. `Release 8.4.8` in this case);
-  * Click to `Publish the release` to create the GitHub release and git tag
-
-  Notes:
-  * the Git tag will be created automatically.
-  * this should be done as soon as the PR is merged, so that the tag
-    is put on the "version bump" commit.
-
-* With the following parameters, [force a build here](https://eve.devsca.com/github/scality/cloudserver/#/builders/3/force/force)
-
-  * Branch Name: The one used for the tag earlier. In this example `development/8.4`
-  * Override Stage: 'release'
-  * Extra properties:
-    * name: `'tag'`, value: `[release version]`, in this example`'8.4.8'`
-
-* Release the release version on Jira
-
-  * Go to the [CloudServer release page](https://scality.atlassian.net/projects/CLDSRV?selectedItem=com.atlassian.jira.jira-projects-plugin:release-page)
-  * Create a next version
-    * Name: `[next version]`, in this example `8.4.9`
-  * Click `...` and select `Release` on the recently released version (`8.4.8`)
-  * Fill in the field to move incomplete version to the next one

-.. important:: Should you want to request for a new backend to be
-               supported, please do so by opening a `Github issue`_,
-               and filling out the "Feature Request" section of our
-               template.
-
-To add support for a new backend support to CloudServer official
-repository, please follow these steps:
-
-- familiarize yourself with our `Contributing Guidelines`_
-- open a `Github issue`_ and fill out Feature Request form, and
-  specify you would like to contribute it yourself;
-- wait for our core team to get back to you with an answer on whether
-  we are interested in taking that contribution in (and hence
-  committing to maintaining it over time);
-- once approved, fork the repository and start your development;
-- use the `forum`_ with any question you may have during the
-  development process;
-- when you think it's ready, let us know so that we create a feature
-  branch against which we'll compare and review your code;
-- open a pull request with your changes against that dedicated feature
-  branch;
-- once that pull request gets merged, you're done.
-
-.. tip::
-
-    While we do take care of the final rebase (when we merge your feature
-    branch on the latest default branch), we do ask that you keep up to date with our latest default branch
-    until then.
-
-.. important::
-
-    If we do not approve your feature request, you may of course still
-    work on supporting a new backend: all our "no" means is that we do not
-    have the resources, as part of our core development team, to maintain
-    this feature for the moment.

-=================
-Add A New Backend
-=================
-
-Supporting all possible public cloud storage APIs is CloudServer's
-ultimate goal. As an open source project, contributions are welcome.
-
-The first step is to get familiar with building a custom Docker image
-for CloudServer.
-
-Build a Custom Docker Image
-~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Clone Zenko's CloudServer, install all dependencies and start the
-service:
-
-.. code-block:: shell
-
-  $ git clone https://github.com/scality/cloudserver
-  $ cd cloudserver
-  $ yarn install
-  $ yarn start
-
-.. tip::
-
-    Some optional dependencies may fail, resulting in you seeing `yarn
-    WARN` messages; these can safely be ignored.  Refer to the User
-    documentation for all available options.
-
-Build the Docker image:
-
-.. code-block:: shell
-
-     # docker build . -t
-     # {{YOUR_DOCKERHUB_ACCOUNT}}/cloudserver:{{OPTIONAL_VERSION_TAG}}
-
-Push the newly created Docker image to your own hub:
-
-.. code-block:: shell
-
-     # docker push
-     # {{YOUR_DOCKERHUB_ACCOUNT}}/cloudserver:{{OPTIONAL_VERSION_TAG}}
-
-.. note::
-
-    To perform this last operation, you need to be authenticated with DockerHub
-
-There are two main types of backend you could want Zenko to support:
-
-== link:S3_COMPATIBLE_BACKENDS.adoc[S3 compatible data backends]
-
-== link:NON_S3_COMPATIBLE_BACKENDS.adoc[Data backends using another protocol than the S3 protocol]

-==========================================================
-Adding support for data backends not supporting the S3 API
-==========================================================
-
-These backends abstract the complexity of multiple APIs to let users
-work on a single common namespace across multiple clouds.
-
-This documents aims at introducing you to the right files in
-CloudServer (the Zenko stack's subcomponent in charge of API
-translation, among other things) to add support to your own backend of
-choice.
-
-General configuration
-~~~~~~~~~~~~~~~~~~~~~
-
-There are a number of constants and environment variables to define to support a
-new data backend; here is a list and where to find them:
-
-:file:`/constants.js`
----------------------
-
- * give your backend type a name, as part of the `externalBackends` object;
- * specify whether versioning is implemented, as part of the
-   `versioningNotImplemented` object;
-
-:file:`/lib/Config.js`
-----------------------
-
- * this is where you should put common utility functions, like the ones to parse
-   the location object from `locationConfig.json`;
- * make sure you define environment variables (like `GCP_SERVICE_EMAIL` as we'll
-   use those internally for the CI to test against the real remote backend;
-
-:file:`/lib/data/external/{{backendName}}Client.js`
----------------------------------------------------
-
- * this file is where you'll instantiate your backend client; this should be a
-   class with a constructor taking the config object built in `/lib/Config.js` as
-   parameter;
- * over time, you may need some utility functions which we've defined in the
-   folder `/api/apiUtils`, and in the file `/lib/data/external/utils`;
-
-:file:`/lib/data/external/utils.js`
------------------------------------
-
- * make sure to add options for `sourceLocationConstraintType` to be equal to
-   the name you gave your backend in :file:`/constants.js`;
-
-:file:`/lib/data/external/{{BackendName}}_lib/`
------------------------------------------------
-
- * this folder is where you'll put the functions needed for supporting your
-   backend; keep your files as atomic as possible;
-
-:file:`/tests/locationConfig/locationConfigTests.json`
-------------------------------------------------------
-
- * this file is where you'll create location profiles to be used by your
-   functional tests;
-
-:file:`/lib/data/locationConstraintParser.js`
----------------------------------------------
-
- * this is where you'll instantiate your client if the operation the end user
-   sent effectively writes to your backend; everything happens inside the
-   function `parseLC()`; you should add a condition that executes if
-   `locationObj.type` is the name of your backend (that you defined in
-   `constants.js`), and instantiates a client of yours. See pseudocode below,
-   assuming location type name is `ztore`:
-
-
-.. code-block:: js
-   :linenos:
-   :emphasize-lines: 12
-
-    (...) //<1>
-    const ZtoreClient = require('./external/ZtoreClient');
-    const { config } = require('../Config'); //<1>
-
-    function parseLC(){ //<1>
-    (...) //<1>
-        Object.keys(config.locationConstraints).forEach(location => { //<1>
-            const locationObj = config.locationConstraints[location]; //<1>
-            (...) //<1>
-            if (locationObj.type === 'ztore' {
-                const ztoreEndpoint = config.getZtoreEndpoint(location);
-                const ztoreCredentials = config.getZtoreCredentials(location); //<2>
-                clients[location] = new ZtoreClient({
-                    ztoreEndpoint,
-                    ztoreCredentials,
-                    ztoreBucketname: locationObj.details.ztoreBucketName,
-                    bucketMatch:  locationObj.details.BucketMatch,
-                    dataStoreName: location,
-                }); //<3>
-                clients[location].clientType = 'ztore';
-            });
-            (...) //<1>
-        });
-    }
-
-
-1. Code that is already there
-2. You may need more utility functions depending on your backend specs
-3. You may have more fields required in your constructor object depending on
-   your backend specs
-
-Operation of type PUT
-~~~~~~~~~~~~~~~~~~~~~
-
-PUT routes are usually where people get started, as it's the easiest to check!
-Simply go on your remote backend console and you'll be able to see whether your
-object actually went up in the cloud...
-
-These are the files you'll need to edit:
-
-:file:`/lib/data/external/{{BackendName}}Client.js`
----------------------------------------------------
-
-- the function that is going to call your `put()` function is also called
-  `put()`, and it's defined in `/lib/data/multipleBackendGateway.js`;
-- define a function with signature like
-  `put(stream, size, keyContext, reqUids, callback)`; this is worth exploring a
-  bit more as these parameters are the same for all backends:
-  //TODO: generate this from jsdoc
-
- - `stream`: the stream of data you want to put in the cloud; if you're
-   unfamiliar with node.js streams, we suggest you start training, as we use
-   them a lot !
-
- - `size`: the size of the object you're trying to put;
-
- - `keyContext`: an object with metadata about the operation; common entries are
-   `namespace`, `buckerName`, `owner`, `cipherBundle`, and `tagging`; if these
-   are not sufficient for your integration, contact us to get architecture
-   validation before adding new entries;
-
- - `reqUids`: the request unique ID used for logging;
-
- - `callback`: your function's callback (should handle errors);
-
-:file:`/lib/data/external/{{backendName}}_lib/`
------------------------------------------------
-
-- this is where you should put all utility functions for your PUT operation, and
-  then import then in :file:`/lib/data/external/{{BackendName}}Client.js`, to keep
-  your code clean;
-
-:file:`tests/functional/aws-node-sdk/test/multipleBackend/put/put{{BackendName}}js`
------------------------------------------------------------------------------------
-
-- every contribution should come with thorough functional tests, showing
-  nominal context gives expected behaviour, and error cases are handled in a way
-  that is standard with the backend (including error messages and code);
-- the ideal setup is if you simulate your backend locally, so as not to be
-  subjected to network flakiness in the CI; however, we know there might not be
-  mockups available for every client; if that is the case of your backend, you
-  may test against the "real" endpoint of your data backend;
-
-:file:`tests/functional/aws-node-sdk/test/multipleBackend/utils.js`
--------------------------------------------------------------------
-
-- where you'll define a constant for your backend location matching your
-  :file:`/tests/locationConfig/locationConfigTests.json`
-- depending on your backend, the sample `keys[]` and associated made up objects
-  may not work for you (if your backend's key format is different, for example);
-  if that is the case, you should add a custom `utils.get{{BackendName}}keys()`
-  function returning ajusted `keys[]` to your tests.
-
-Operation of type GET
-~~~~~~~~~~~~~~~~~~~~~
-
-GET routes are easy to test after PUT routes are implemented, hence why we're
-covering them second.
-
-These are the files you'll need to edit:
-
-:file:`/lib/data/external/{{BackendName}}Client.js`
----------------------------------------------------
-
-- the function that is going to call your `get()` function is also called
-  `get()`, and it's defined in `/lib/data/multipleBackendGateway.js`;
-- define a function with signature like
-  `get(objectGetInfo, range, reqUids, callback)`; this is worth exploring a
-  bit more as these parameters are the same for all backends:
-
-//TODO: generate this from jsdoc
-
- - `objectGetInfo`: a dictionary with two entries: `key`, the object key in the
-   data store, and `client`, the data store name;
-
- - `range`: the range of bytes you will get, for "get-by-range" operations (we
-   recommend you do simple GETs first, and then look at this);
-
- - `reqUids`: the request unique ID used for logging;
-
- - `callback`: your function's callback (should handle errors);
-
-:file:`/lib/data/external/{{backendName}}_lib/`
------------------------------------------------
-
-- this is where you should put all utility functions for your GET operation, and
-  then import then in `/lib/data/external/{{BackendName}}Client.js`, to keep
-  your code clean;
-
-:file:`tests/functional/aws-node-sdk/test/multipleBackend/get/get{{BackendName}}js`
------------------------------------------------------------------------------------
-
-- every contribution should come with thorough functional tests, showing
-  nominal context gives expected behaviour, and error cases are handled in a way
-  that is standard with the backend (including error messages and code);
-- the ideal setup is if you simulate your backend locally, so as not to be
-  subjected to network flakiness in the CI; however, we know there might not be
-  mockups available for every client; if that is the case of your backend, you
-  may test against the "real" endpoint of your data backend;
-
-:file:`tests/functional/aws-node-sdk/test/multipleBackend/utils.js`
--------------------------------------------------------------------
-
-.. note:: You should need this section if you have followed the tutorial in order
-          (that is, if you have covered the PUT operation already)
-
-- where you'll define a constant for your backend location matching your
-  :file:`/tests/locationConfig/locationConfigTests.json`
-- depending on your backend, the sample `keys[]` and associated made up objects
-  may not work for you (if your backend's key format is different, for example);
-  if that is the case, you should add a custom `utils.get{{BackendName}}keys()`
-
-Operation of type DELETE
-~~~~~~~~~~~~~~~~~~~~~~~~
-
-DELETE routes are easy to test after PUT routes are implemented, and they are
-similar to GET routes in our implementation, hence why we're covering them
-third.
-
-These are the files you'll need to edit:
-
-:file:`/lib/data/external/{{BackendName}}Client.js`
----------------------------------------------------
-
-- the function that is going to call your `delete()` function is also called
-  `delete()`, and it's defined in :file:`/lib/data/multipleBackendGateway.js`;
-- define a function with signature like
-  `delete(objectGetInfo, reqUids, callback)`; this is worth exploring a
-  bit more as these parameters are the same for all backends:
-
-//TODO: generate this from jsdoc
- * `objectGetInfo`: a dictionary with two entries: `key`, the object key in the
-   data store, and `client`, the data store name;
- * `reqUids`: the request unique ID used for logging;
- * `callback`: your function's callback (should handle errors);
-
-:file:`/lib/data/external/{{backendName}}_lib/`
------------------------------------------------
-

-  and then import then in `/lib/data/external/{{BackendName}}Client.js`, to keep
-  your code clean;
-

------------------------------------------------------------------------------------------
-
-- every contribution should come with thorough functional tests, showing
-  nominal context gives expected behaviour, and error cases are handled in a way
-  that is standard with the backend (including error messages and code);
-- the ideal setup is if you simulate your backend locally, so as not to be
-  subjected to network flakiness in the CI; however, we know there might not be
-  mockups available for every client; if that is the case of your backend, you
-  may test against the "real" endpoint of your data backend;
-
-:file:`tests/functional/aws-node-sdk/test/multipleBackend/utils.js`
--------------------------------------------------------------------
-
-.. note:: You should need this section if you have followed the
-          tutorial in order (that is, if you have covered the PUT operation
-          already)
-

-  may not work for you (if your backend's key format is different, for example);
-  if that is the case, you should add a custom `utils.get{{BackendName}}keys()`
-
-Operation of type HEAD
-~~~~~~~~~~~~~~~~~~~~~~
-
-HEAD routes are very similar to DELETE routes in our implementation, hence why
-we're covering them fourth.
-
-These are the files you'll need to edit:
-
-:file:`/lib/data/external/{{BackendName}}Client.js`
----------------------------------------------------
-
-- the function that is going to call your `head()` function is also called
-  `head()`, and it's defined in :file:`/lib/data/multipleBackendGateway.js`;
-- define a function with signature like
-  `head(objectGetInfo, reqUids, callback)`; this is worth exploring a
-  bit more as these parameters are the same for all backends:
-

- * `objectGetInfo`: a dictionary with two entries: `key`, the object key in the
-   data store, and `client`, the data store name;
- * `reqUids`: the request unique ID used for logging;
- * `callback`: your function's callback (should handle errors);

-  and then import then in :file:`/lib/data/external/{{BackendName}}Client.js`, to keep
-  your code clean;
-
-:file:`tests/functional/aws-node-sdk/test/multipleBackend/get/get{{BackendName}}js`
------------------------------------------------------------------------------------
-
-- every contribution should come with thorough functional tests, showing
-  nominal context gives expected behaviour, and error cases are handled in a way

-          (that is, if you have covered the PUT operation already)

-  may not work for you (if your backend's key format is different, for example);
-  if that is the case, you should add a custom `utils.get{{BackendName}}keys()`
-
-Healthcheck
-~~~~~~~~~~~
-
-Healtchecks are used to make sure failure to write to a remote cloud is due to
-a problem on that remote cloud, an not on Zenko's side.
-This is usually done by trying to create a bucket that already exists, and
-making sure you get the expected answer.
-
-These are the files you'll need to edit:
-
-:file:`/lib/data/external/{{BackendName}}Client.js`
----------------------------------------------------
-
-- the function that is going to call your `healthcheck()` function is called
-  `checkExternalBackend()` and it's defined in
-  :file:`/lib/data/multipleBackendGateway.js`; you will need to add your own;
-- your healtcheck function should get `location` as a parameter, which is an
-  object comprising:`
-
- * `reqUids`: the request unique ID used for logging;
- * `callback`: your function's callback (should handle errors);
-
-:file:`/lib/data/external/{{backendName}}_lib/{{backendName}}_create_bucket.js`
--------------------------------------------------------------------------------
-
-- this is where you should write the function performing the actual bucket
-  creation;
-
-:file:`/lib/data/external/{{backendName}}_lib/utils.js`
--------------------------------------------------------
-
-- add an object named per your backend's name to the `backendHealth` dictionary,
-  with proper `response` and `time` entries;
-
-:file:`lib/data/multipleBackendGateway.js`
-------------------------------------------
-
-- edit the `healthcheck` function to add your location's array, and call your
-  healthcheck; see pseudocode below for a sample implementation, provided your
-  backend name is `ztore`
-
-
-.. code-block:: js
-   :linenos:
-
-    (...) //<1>
-
-        healthcheck: (flightCheckOnStartUp, log, callback) => { //<1>
-            (...) //<1>
-            const ztoreArray = []; //<2>
-            async.each(Object.keys(clients), (location, cb) => { //<1>
-                (...) //<1>
-                } else if (client.clientType === 'ztore' {
-                    ztoreArray.push(location); //<3>
-                    return cb();
-                }
-            (...) //<1>
-            multBackendResp[location] = { code: 200, message: 'OK' }; //<1>
-            return cb();
-        }, () => { //<1>
-            async.parallel([
-                (...) //<1>
-                next => checkExternalBackend( //<4>
-                    clients, ztoreArray, 'ztore', flightCheckOnStartUp,
-                    externalBackendHealthCheckInterval, next),
-            ] (...) //<1>
-            });
-            (...) //<1>
-        });
-    }
-
-1. Code that is already there
-2. The array that will store all locations of type 'ztore'
-3. Where you add locations of type 'ztore' to the array
-4. Where you actually call the healthcheck function on all 'ztore' locations
-
-Multipart upload (MPU)
-~~~~~~~~~~~~~~~~~~~~~~
-
-This is the final part to supporting a new backend! MPU is far from
-the easiest subject, but you've come so far it shouldn't be a problem.
-
-These are the files you'll need to edit:
-
-:file:`/lib/data/external/{{BackendName}}Client.js`
----------------------------------------------------
-
-You'll be creating four functions with template signatures:
-
-- `createMPU(Key, metaHeaders, bucketName, websiteRedirectHeader, contentType,
-  cacheControl, contentDisposition, contentEncoding, log, callback)` will
-  initiate the multi part upload process; now, here, all parameters are
-  metadata headers except for:
-
- * `Key`, the key id for the final object (collection of all parts);
- * `bucketName`, the name of the bucket to which we will do an MPU;
- * `log`, the logger;
-
-- `uploadPart(request, streamingV4Params, stream, size, key, uploadId, partNumber, bucketName, log, callback)`
-   will be called for each part; the parameters can be explicited as follow:
-
- * `request`, the request object for putting the part;
- * `streamingV4Params`, parameters for auth V4 parameters against S3;
- * `stream`, the node.js readable stream used to put the part;
- * `size`, the size of the part;
- * `key`, the key of the object;
- * `uploadId`, multipart upload id string;
- * `partNumber`, the number of the part in this MPU (ordered);
- * `bucketName`, the name of the bucket to which we will do an MPU;
- * `log`, the logger;
-
-- `completeMPU(jsonList, mdInfo, key, uploadId, bucketName, log, callback)` will
-   end the MPU process once all parts are uploaded; parameters can be explicited
-   as follows:
-
- * `jsonList`, user-sent list of parts to include in final mpu object;
- * `mdInfo`, object containing 3 keys: storedParts, mpuOverviewKey, and
-   splitter;
- * `key`, the key of the object;
- * `uploadId`, multipart upload id string;
- * `bucketName`, name of bucket;
- * `log`, logger instance:
-
-- `abortMPU(key, uploadId, bucketName, log, callback)` will handle errors, and
-  make sure that all parts that may have been uploaded will be deleted if the
-  MPU ultimately fails; the parameters are:
-
- * `key`, the key of the object;
- * `uploadId`, multipart upload id string;
- * `bucketName`, name of bucket;
- * `log`, logger instance.

-:file:`/lib/api/objectPutPart.js`
----------------------------------
-
-- you'll need to add your backend type in appropriate sections (simply look for
-  other backends already implemented).
-
-:file:`/lib/data/external/{{backendName}}_lib/`
------------------------------------------------
-

-   :linenos:
-
-    (...) //<1>
-        createMPU:(key, metaHeaders, bucketName, websiteRedirectHeader, //<1>
-         location, contentType, cacheControl, contentDisposition,
-         contentEncoding, log, cb) => {
-            const client = clients[location]; //<1>
-            if (client.clientType === 'aws_s3') { //<1>
-                return client.createMPU(key, metaHeaders, bucketName,
-                websiteRedirectHeader, contentType, cacheControl,

-                return client.createMPU(key, metaHeaders, bucketName,
-                  websiteRedirectHeader, contentType, cacheControl,

-S3-Compatible Backends
-======================
-
-
-Adding Support in CloudServer
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-This is the easiest case for backend support integration: there is nothing to do
-but configuration!  Follow the steps described in our
-:ref:`use-public-cloud` and make sure you:
-
-- set ``details.awsEndpoint`` to your storage provider endpoint;
-
-- use ``details.credentials`` and *not* ``details.credentialsProfile`` to set your
-  credentials for that S3-compatible backend.
-
-For example, if you’re using a Wasabi bucket as a backend, then your region
-definition for that backend will look something like:
-::
-
-    "wasabi-bucket-zenkobucket": {
-    "type": "aws_s3",
-    "legacyAwsBehavior": true,
-    "details": {
-    "awsEndpoint": "s3.wasabisys.com",
-    "bucketName": "zenkobucket",
-    "bucketMatch": true,
-    "credentials": {
-    "accessKey": "\\{YOUR_WASABI_ACCESS_KEY}",
-    "secretKey": "\\{YOUR_WASABI_SECRET_KEY}"
-    }
-    }
-    },
