Question about using the various CNI

[lchunleo]

Hi

Am starting out to learn and use rke2. However, i like to have some advice to use rke2 in air gap. I understand that i can install different CNI from the asset download. However, i wish to know if e.g. i install canal as my cni and in future i wish to add calico or weavenet , do i need to uninstall everything and do a reinstallation?. Or i have to use the multux to install before i can add various CNI into it. Thanks

Changing CNIs after the cluster has been deployed is not something supported in Kubernetes. So, yes, you'll need to reinstall

Reading the air gap instructions, can i check if my understanding is correct to deploy rke2 with weavenet.. https://docs.rke2.io/install/airgap

1. Go to the asset and download the 1) sha256-amd..txt 2) rke2-images-linux-amd64 3) rke2-images-core-linux-amd64 4)install.sh
2. Based on the required own CNI and follow the instructions there? (or need to do something to link up the rke2 with the new CNI?)

Thanks
