-------------------------------------------------------------------------------------
Cluster setups:
list to list all of the managed clusters
checkout <cluster> to switch default kubeconfig of the cluster
new <cluster> to start a new k8s deploy with name 'cluster'
setup <cluster> <step> to setup a cluster, also supporting a step-by-step way
start <cluster> to start all of the k8s services stopped by 'ezctl stop'
stop <cluster> to stop all of the k8s services temporarily
upgrade <cluster> to upgrade the k8s cluster
destroy <cluster> to destroy the k8s cluster
backup <cluster> to backup the cluster state (etcd snapshot)
restore <cluster> to restore the cluster state from backups
start-aio to quickly setup an all-in-one cluster with 'default' settings
Cluster ops:
add-etcd <cluster> <ip> to add a etcd-node to the etcd cluster
add-master <cluster> <ip> to add a master node to the k8s cluster
add-node <cluster> <ip> to add a work node to the k8s cluster
del-etcd <cluster> <ip> to delete a etcd-node from the etcd cluster
del-master <cluster> <ip> to delete a master node from the k8s cluster
del-node <cluster> <ip> to delete a work node from the k8s cluster
Extra operation:
kcfg-adm <cluster> <args> to manage client kubeconfig of the k8s cluster
Use "ezctl help <command>" for more information about a given command.
