From logs, you can see calico-node is not able to autodetect any IPv4 address

Updating IP_AUTODETECTION_METHOD to use specific interface made it work

$ cat /var/snap/microk8s/current/args/cni-network/cni.yaml | grep br-api
              value: "interface=br-api"

User should be able to configure this setting in sunbeam.
