Hi! There is a proper way to change host IP of master node on k3s running cluster ?(can be single-node or multi-node). when changing IP address k3s service is not starting. is there correct way without deleting node to change IP? Thanks

There is no kubernetes API to do this. At your own risk, you could stop k3s service, modify the

node-ip

config and restart the k3s service. But there might be connectivity problems. This is a use case that is not tested

For a multi node cluster the best and I think correct thing is to remove a node and add it back in with the new ip. I have done with to reply all my controllers with new devices.

Thanks @bland-account-99790 I tried it after restart k3s service i got error

Failed to test data store connection: this server is a not a member of the etcd cluster.

looking for old IP Tried to remove

/var/lib/rancher/k3s/server/db/etcd/member/*

k3s start successfully but all resources have been removed. Thanks @cool-room-99795
