etcd does not provide enough flexibility to configure server SSL and
client authentication separately. When configuring server SSL the
`--ca-file` flag is required to trust self-signed SSL certificates
used to service client requests.
The `--ca-file` has the side effect of enabling client cert
authentication. This can be surprising for those looking to simply
secure communication between an etcd server and client.
Resolve this issue by introducing four new flags:
--client-cert-auth
--peer-client-cert-auth
--trusted-ca-file
--peer-trusted-ca-file
These new flags will allow etcd to support a more explicit SSL
configuration for both etcd clients and peers.
Example usage:
Start etcd with server SSL and no client cert authentication:
etcd -name etcd0 \
--advertise-client-urls https://etcd0.example.com:2379 \
--cert-file etcd0.example.com.crt \
--key-file etcd0.example.com.key \
--trusted-ca-file ca.crt
Start etcd with server SSL and enable client cert authentication:
etcd -name etcd0 \
--advertise-client-urls https://etcd0.example.com:2379 \
--cert-file etcd0.example.com.crt \
--key-file etcd0.example.com.key \
--trusted-ca-file ca.crt \
--client-cert-auth
Start etcd with server SSL and client cert authentication for both
peer and client endpoints:
etcd -name etcd0 \
--advertise-client-urls https://etcd0.example.com:2379 \
--cert-file etcd0.example.com.crt \
--key-file etcd0.example.com.key \
--trusted-ca-file ca.crt \
--client-cert-auth \
--peer-cert-file etcd0.example.com.crt \
--peer-key-file etcd0.example.com.key \
--peer-trusted-ca-file ca.crt \
--peer-client-cert-auth
This change is backwards compatible with etcd versions 2.0.0+. The
current behavior of the `--ca-file` flag is preserved.
Fixes #2499.
