Create and operate managed clusters

Note

This tutorial applies only to the Container Cloud web UI users with the m:kaas:namespace@operator or m:kaas:namespace@writer access role assigned by the Infrastructure Operator. To add a bare metal host, the m:kaas@operator or m:kaas:namespace@bm-pool-operator role is required.

After you deploy the Mirantis Container Cloud management cluster, you can start creating managed clusters depending on your cloud needs.

The deployment procedure is performed using the Container Cloud web UI and comprises the following steps:

1. Create a dedicated non-default project for managed clusters.

2. Create and configure bare metal hosts with corresponding labels for machines such as worker, manager, or storage.

3. Create an initial cluster configuration.

4. Add the required amount of machines with the corresponding configuration to the managed cluster.

5. Add a Ceph cluster.

Note

The Container Cloud web UI communicates with Keycloak to authenticate users. Keycloak is exposed using HTTPS with self-signed TLS certificates that are not trusted by web browsers.

To use your own TLS certificates for Keycloak, refer to Configure TLS certificates for cluster applications.

Cluster creation and configuration

• Create a project for managed clusters
• Generate a kubeconfig for a managed cluster using API
• Create and operate a baremetal-based managed cluster
• Add or update a CA certificate for a MITM proxy using API
• Change a cluster configuration
• Disable a machine

Cluster update

• Configure the parallel update of worker nodes
• Create update groups for worker machines
• Change the upgrade order of a machine or machine pool
• Update a managed cluster
• Update a patch Cluster release of a managed cluster
