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.
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.
