Delete a machine

Delete a machine

This section instructs you on how to scale down an existing managed cluster through the Mirantis Container Cloud web UI.


An operational managed cluster deployment must contain a minimum of 3 Kubernetes manager nodes and 2 Kubernetes worker nodes. The deployment of the cluster does not start until the minimum number of nodes is created.

To meet the etcd quorum and to prevent the deployment failure, deletion of the manager nodes is prohibited.

A machine with the manager node role is automatically deleted during the managed cluster deletion.

To delete a machine from a managed cluster:

  1. Log in to the Container Cloud web UI with the writer permissions.

  2. Switch to the required project using the Switch Project action icon located on top of the main left-side navigation panel.

  3. In the Clusters tab, click on the required cluster name to open the list of machines running on it.

  4. Click the More action icon in the last column of the machine you want to delete and select Delete. Confirm the deletion.

Deleting a machine automatically frees up the resources allocated to this machine.
