07/05/2023, 2:59 PM@bland-account-99790 great thanks for your help. So how could I add multus support on a node after it is in my cluster.
Should I first kick it out, and then add it back into my cluster to enable multus.

07/05/2023, 3:09 PMA CNI plugin is not something that can be configured per node. It is something that affects the whole cluster

07/05/2023, 3:09 PMIf you want to do it properly, you should destroy and redeploy the rke2 cluster using the multus config

07/05/2023, 3:10 PMIf you just want to play with it in a non-production env, you can follow multus upstream instructions which explain how to deploy it in a live env. Let me try to find those for you

And I wonder to know is there no way to upgrade my cluster to support multus if it only enabled canal at the beginning?
So the only solution is that I need to migrate all my workload to a new cluster.
Could you give me some advice about it.

07/05/2023, 7:22 PMThere is a bit outdated instruction for doing a live migration https://cilium.io/blog/2020/10/06/skybet-cilium-migration/

07/05/2023, 7:22 PMMaybe you can try to do something like that

07/06/2023, 11:27 AMI found that multus could be installed on the fly, because only new pods will be affected and because the pod is still use the same cni underlying the multus, so there would be no network connectivity issues. thanks
