Usage: easzctl COMMAND [args]
|
|
|
|
Cluster-wide operation:
|
|
checkout To switch to context <clustername>, or create it if not existed
|
|
destroy To destroy the current cluster, '--purge' to also delete the context
|
|
list To list all of clusters managed
|
|
setup To setup a cluster using the current context
|
|
start-aio To quickly setup an all-in-one cluster for testing (like minikube)
|
|
|
|
In-cluster operation:
|
|
add-etcd To add a etcd-node to the etcd cluster
|
|
add-master To add a kube-master(master node) to the k8s cluster
|
|
add-node To add a kube-node(work node) to the k8s cluster
|
|
del-etcd To delete a etcd-node from the etcd cluster
|
|
del-master To delete a kube-master from the k8s cluster
|
|
del-node To delete a kube-node from the k8s cluster
|
|
upgrade To upgrade the k8s cluster
|
|
|
|
Extra operation:
|
|
basic-auth To enable/disable basic-auth for apiserver
|
|
|
|
Use "easzctl help <command>" for more information about a given command.
