Cluster startup & shutdown

Startup and shutdown of the cluster where Cocktail is installed must be performed sequentially.

Startup

For startups, master nodes must be activated before worker nodes.

1) Master Node

# systemctl start etcd
# systemctl start flanneld
# systemctl start docker
# systemctl start kubelet

2) Worker Node

# systemctl start flanneld
# systemctl start docker
# systemctl start kubelet

Shutdown

Conversely, worker nodes must be deactivated before master nodes for shutdowns.

1) Worker Node

# systemctl stop kubelet
# systemctl stop docker
# systemctl stop flanneld
# systemctl stop etcd

2) Master Node

# systemctl stop kubelet
# systemctl stop docker
# systemctl stop flanneld
