Microk8s stuck and cannot connect to VM on MacOS

[aaronpliu]

Summary

I installed Microk8s latest version on MacOS M2. it was working fine after installation, but weird behavior appeared after it running for a couple of days that whatever type multipass command or microk8s kubectl command to access, it's very slow or no response. Even if I use k9s to access, it lost all of connection info. Firstly, I doubt it's due to Apple M2 issue, then switch to Apple Intel, it's still same issue.

I really would like to install an available k8s cluster in MacOS. However, microk8s cannot be running with stable status. Actually, I did not install any other image there (Only enable required plugins, like registry, dns, dashboard, istio...etc).

Btw, I stopped microk8s instance and restart a new one, the IP address changed, and microk8s is OK to access again (it still repeat the same behavior, become slow -> not access -> no response for kubectl command -> down)

@aaronpliu would you be able to share an inspection report tarball so we have a look at the logs (microk8s inspect).

I had this issue with channel 1.26 installed, and was able to solve it by upgrading MicroK8s to a later version
(in my case: channel 1.29/stable), like so:

microk8s uninstall
(...)
microk8s install --channel=1.29/stable

(still getting Warning: the "--mem" long option is deprecated in favour of "--memory".
but apart from that it seems to be working)

Have used this guide to choose a stable channel:
