There are a few issues with the kube-ovn addon: - While enabling, it may timeout while waiting for the Calico pods to disappear. This may happen if its service account / cluster role / cluster role binding gets deleted, it can no longer fetch ClusterInformation. We're now removing them beforehand, and waiting for them to disappear. - The CNI_CONF_DIR should be /var/snap/microk8s/current/args/cni-network - When disabling, we should remove the 01-kube-ovn.conflist file from $CNI_CONF_DIR, otherwise kube-ovn may be used for future pods, even though the kube-ovn addon is not enabled. - When disabling, reenable the default CNI and rollout the CoreDNS deployment, so it can use the default CNI. - POD_CIDR, POD_GATEWAY, SVC_CIDR, JOIN_CIDR are not configurable, which may conflict with a node's CIDR, resulting in the kube-ovn not deploying properly.
The test will enable the kube-ovn addon and test the network connectivity by creating an nginx pod and service, and try to connect to that nginx through the cluster IP. Afterwards, the test will disable the addon, and test the network connectivity again.
