Dedicated network for Kubernetes pods traffic on bare metal clusters

Technology Preview

Implemented the k8s-pods bridge in L2 templates that allows you to use a dedicated network for Kubernetes pods traffic. When the k8s-pods bridge is defined in an L2 template, Calico CNI uses that network for routing the pods traffic between nodes.

Caution

Using of a dedicated network for Kubernetes pods traffic described above is available as Technology Preview. Use such configuration for testing and evaluation purposes only. For the Technology Preview feature definition, refer to Technology Preview features.

The following features are still under development and will be announced in one of the following Container Cloud releases:

  • Switching Kubernetes API to listen to the specified IP address on the node

  • Enable MetalLB to listen and respond on the dedicated virtual bridge.
