Delete Cluster Node Removal

sealos delete is a command in the Sealos command line tool, mainly used to remove nodes from the cluster. This guide will detail its usage and options.

Note to ensure the number of control nodes is odd to ensure normal election of etcd

Basic Usage

Delete Node

To remove a node from the cluster, you can use the --nodes option:

sealos delete --nodes x.x.x.x

In the above command, x.x.x.x should be replaced with the IP address of the node you want to delete. If you accidentally delete the wrong node, you can use the sealos add command to recover it:

sealos add --nodes x.x.x.x

Delete Control Node

To remove a control node from the cluster, you can use the --masters option:

sealos delete --masters x.x.x.x

Please note, if the --masters parameter is specified, sealos will delete your control node.

Delete Control Node and Node

If you want to delete both control nodes and nodes at the same time, you can use the --masters and --nodes options at the same time:

sealos delete --masters x.x.x.x --nodes x.x.x.x
sealos delete --masters x.x.x.x-x.x.x.y --nodes x.x.x.x-x.x.x.y


The sealos delete command provides the following options:

  • --cluster='default': The name of the cluster to which the deletion operation applies. The default is default.

  • --force=false: You can enter a --force flag to force delete nodes.

  • --masters='': The control nodes to be removed.

  • --nodes='': The nodes to be removed.

Each option can be followed by an argument.
