Pod and Service CIDR ConflictsΒΆ

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.
