Multus is no longer starting (infinite loop) about microk8s HOT 8 OPEN

Hi @ohault

What environment are you using? Is this perhaps on LXD? One thing you could try as a work-around is to edit the multus daemonset and remove the MountPropagation: Bidirectional line from https://github.com/canonical/microk8s-community-addons/blob/ec3dddc5a3b7efac45fe81daca35eba6b3b81ec0/addons/multus/multus.yaml#L160

from microk8s.

I'm using WSL2.

OK, thank you. Could you check whether the proposed workaround above helps?

No so easy to test as multus.yaml is in ro in the /snap tree because I used snap to install microk8s.
Feel free to you tell me how I can test it ?
I can do it under WSL2/Ubuntu 20.4.6.

OK, the addons themselves are read-write, and can be found under /var/snap/microk8s/common/addons. You could edit the manifest at /var/snap/microk8s/common/addons/community/addons/multus then enable the addon

It's exactly what I tried, but I got an error message like "The filesystem is read only".

I think there must be a mixup here. The read-only parts of microk8s will be in /snap/microk8s/current/.... /var/snap/microk8s/common/... will not be readonly (it is actively used for microk8s to store and maintain the current state).

Can you try editing the file again? The command should be

sudo vim /var/snap/microk8s/common/addons/community/addons/multus/multus.yaml

Or can you share the exact error message that you are getting?

I have just tried from a fresh new system.
I confirm that on the new system, I have been able to modify the file /var/snap/microk8s/common/addons/community/addons/multus/multus.yaml
I don't understand why this was not the case, but it's a detail.
I confirm also that by removing the line "MountPropagation: Bidirectional" fix the multus starting issue.
