Add a machine

This section describes how to add a machine to a newly created managed cluster using either the Mirantis Container Cloud web UI or CLI for an advanced configuration.

Warning

An operational managed cluster 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.

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

Before Container Cloud 2.17.0, to meet the etcd quorum and prevent the deployment failure, deletion of the manager nodes was prohibited.

Since Container Cloud 2.17.0, you can delete manager machines within the Technology Preview features scope with several precautions. For details, see Precautions.
