microk8s.reset hangs when addons are enabled

[balchua]

Sometimes when addons using CRDs or api-services, resetting the cluster hangs during namespace deletion.
Reset also does not properly cleanup addon other resources such as service accounts, clusterroles, etc..

Hi, I am not really sure if its the addons that's causing this problem. I tried disabling the addons and running microk8s.reset then. The command hangs after the namespace deletion. Any suggestions?

This usually happens when crds are still being used. If somewhere you have crds used in a namespace, you must delete it first prior to deleting the namespace.

@mayankshah1607 thanks for the info. I was thinking about this further, perhaps should move the crd deletion earlier.

Will try this one out. Thanks 👍

I'm still seeing this as well, even after trying @balchua's suggestion.

@ukd1 apiservices also needs to be deleted before the namespace. Otherwise it will be stuck in Terminating state.

kubectl delete apiservices --all. IIRC.
