Management cluster operations¶
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.
Caution
Regional clusters are unsupported since Container Cloud 2.25.0 (Cluster releases 17.0.0 and 16.0.0). Mirantis does not perform functional integration testing of the feature and the related code is removed in Container Cloud 2.26.0 (Cluster releases 17.1.0 and 16.1.0). If you still require this feature, contact Mirantis support for further information.
This section covers the management aspects of the bare metal management cluster that MOSK is based on.
The Mirantis Container Cloud web UI enables you to perform the following operations with management clusters:
View the cluster details (such as cluster ID, creation date, node count, and so on) as well as obtain a list of cluster endpoints including the StackLight components, depending on your deployment configuration.
To view generic cluster details, in the Clusters tab, click the More action icon in the last column of the required cluster and select Cluster info.
Note
Adding more than 3 nodes to a management cluster is not supported.
Removing a management cluster using the Container Cloud web UI is not supported. Use the dedicated cleanup script instead. For details, see Remove a management cluster.
Verify the current release version of the cluster including the list of installed components with their versions and the cluster release change log.
To view details of a Cluster release version, in the Clusters tab, click the version in the Release column next to the name of the required cluster.
