Delete a managed cluster¶
Due to a development limitation in
deletion of a managed cluster requires preliminary deletion
of the worker machines running on the cluster.
Using the Container Cloud web UI, first delete worker machines one by one until you hit the minimum of 2 workers for an operational cluster. After that, you can delete the cluster with the remaining workers and managers.
To delete a baremetal-based managed cluster:
Log in to the Mirantis Container Cloud web UI with the
Switch to the required project using the Switch Project action icon located on top of the main left-side navigation panel.
In the Clusters tab, click the required cluster name to open the list of machines running on it.
Click the More action icon in the last column of the worker machine you want to delete and select Delete. Confirm the deletion.
Repeat the step above until you have 2 workers left.
In the Clusters tab, click the More action icon in the last column of the required cluster and select Delete.
Verify the list of machines to be removed. Confirm the deletion.
Optional. If you do not plan to reuse the credentials of the deleted cluster, delete them:
In the Credentials tab, click the Delete credential action icon next to the name of the credentials to be deleted.
Confirm the deletion.
You can delete credentials only after deleting the managed cluster they relate to.
Deleting a cluster automatically frees up the resources allocated for this cluster, for example, instances, load balancers, networks, floating IPs, and so on.
