Comment 4 for bug 1976318

Hi George, thank you for looking in to this.

I reproduced the issue by adding relation between worker charm and the openstack-integrator charm.

        $ kubectl get nodes -o wide
        NAME STATUS ROLES AGE VERSION INTERNAL-IP EXTERNAL-IP OS-IMAGE KERNEL-VERSION CONTAINER-RUNTIME
        master-1 Ready <none> 27h v1.24.1 192.168.150.50 <none> Ubuntu 20.04.4 LTS 5.4.0-109-generic containerd://1.5.9
        worker-1 Ready <none> 27h v1.24.1 192.168.150.51 <none> Ubuntu 20.04.4 LTS 5.4.0-109-generic containerd://1.5.9
        worker-2 Ready <none> 27h v1.24.1 192.168.150.52 <none> Ubuntu 20.04.4 LTS 5.4.0-109-generic containerd://1.5.9
        worker-3 Ready <none> 27h v1.24.1 192.168.141.41 <none> Ubuntu 20.04.4 LTS 5.4.0-109-generic containerd://1.5.9

Here is the requested output:

        $ juju run -m k8s --unit kubernetes-worker/2 -- network-get kube-control
        bind-addresses:
        - mac-address: fa:16:3e:e2:d7:70
          interface-name: ens3
          addresses:
          - hostname: ""
            address: 192.168.150.53
            cidr: 192.168.150.0/24
          macaddress: fa:16:3e:e2:d7:70
          interfacename: ens3
        - mac-address: 7e:54:d9:66:e6:20
          interface-name: fan-252
          addresses:
          - hostname: ""
            address: 252.53.0.1
            cidr: 252.0.0.0/8
          macaddress: 7e:54:d9:66:e6:20
          interfacename: fan-252
        egress-subnets:
        - 192.168.150.53/32
        ingress-addresses:
        - 192.168.150.53
        - 252.53.0.1

So it seems that the charm doesn't see the other Openstack networks. By the way, --node-ip in the kubelet's cmdline arguments is also correct:

        $ juju ssh -m k8s kubernetes-worker/2 'ps aux | grep kubelet | grep node-ip'
