Pod and Service CIDR Conflicts

If, after installing a MetalK8s cluster you notice routing issues in pod-to-pod communication:

  1. Check the configured values for the internal pod and service networks.

    [root@bootstrap]# salt-call pillar.get networks
local:
    ----------
    control_plane:
        172.21.254.0/28
    pod:
        10.233.0.0/16
    service:
        10.96.0.0/12
    workload_plane:
        172.21.254.32/27
  2. Ensure that the configured IP ranges (CIDR notation) do not conflict with your infrastructure.
