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 is prohibited.

  • Since Container Cloud 2.17.0, deletion of the manager nodes is allowed for non-MOSK-based clusters within the Technology Preview features scope for the purpose of node replacement or recovery.
