Simple bridge network for kubernetes

How it works

bridget - it's short shell script, that helps you for organise simple bridge network for Kubernetes. There is no overlays, no politics. Just flat L2-network across all your hosts and pods.

In addition bridget can automatically configure VLAN and bridge interfaces for that. See the picture:

bridget automatically retrieves IP-addresses from your pod-network, and configures cni for use it. Collision check is carried out each new run by arping tool.

Parameters

  • BRIDGE (example: cbr0) - Bridge name. Mandatory option.
  • VLAN (example: 100) - VLAN id. If set, the new vlan-interface under IFACE will be created, then added to BRIDGE.
  • IFACE (example: eth0) - Physical interface for connect to bridge. Mandatory if VLAN is set, but can be used singly.
  • MTU (default: 1500) - MTU value for cni config
  • CHECK_SLAVES (example: 1) - Make bridget for configure slave interfaces, if bridge already exists.
  • POD_NETWORK (default: 10.244.0.0/16) - Your pod network.
  • DIVISION_PREFIX (default: 24) - Network CIDR prefix for devide your POD_NETWORK.
  • DEBUG (example: 1) - Enable verbose output.
