Add and delete nodes in RKE K8S cluster
Rke deletes the node:
Modify cluster.yal to delete the configuration of the node that needs to be deleted, and then run
[root@cnvs-kubm-101-103 rke] # more cluster.ymlnodes:-address: 172.20.101.103 user: ptmind role: [controlplane,worker,etcd]-address: 172.20.101.104 user: ptmind role: [controlplane,worker,etcd]-address: 172.20.101.105 user: ptmind role: [controlplane,worker Etcd] delete #-address: 172.20.101.106 delete # user: ptmind delete # role: [worker] delete # labels: {traefik: traefik-outer} perform delete node operation
