Delete a machine

Delete a machine

This section instructs you on how to scale down an existing managed cluster through the Docker Enterprise (DE) Container Cloud web UI.

Warning

A machine with the manager node role cannot be deleted manually. A machine with such role is automatically deleted during the managed cluster deletion.

To delete a machine from a managed cluster:

  1. Log in to the DE 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.

Warning

The operational managed cluster should contain minimum 3 Kubernetes manager nodes and 2 Kubernetes worker nodes. To meet the etcd quorum and to prevent the deployment failure, scaling down of the manager nodes is prohibited.
