Mirantis Container Cloud (MCC) becomes part of Mirantis OpenStack for Kubernetes (MOSK)!

Starting with MOSK 25.2, the MOSK documentation set covers all product layers, including MOSK management (formerly Container Cloud). This means everything you need is in one place. Some legacy names may remain in the code and documentation and will be updated in future releases. The separate Container Cloud documentation site will be retired, so please update your bookmarks for continued easy access to the latest content.

LCM custom resources

The Kubernetes LCM components handle the following custom resources (CRs):

LCMMachine

Describes a machine that is located on a cluster. Contains the machine type, control, or worker StateItems that correspond to Ansible playbooks and miscellaneous actions, for example, downloading a file or executing a shell command. LCMMachine reflects the current state of a machine, for example, a node IP address, and each StateItem through its status. Multiple LCMMachine CRs can correspond to a single cluster.

LCMCluster

Describes a MOSK cluster. In its spec, LCMCluster contains a set of StateItems for each type of LCMMachine, which describe the actions that must be performed to deploy the cluster. LCMCluster is created by the provider using machineTypes of the Release object. The status field of LCMCluster reflects the status of the cluster, for example, the number of ready or requested nodes.

HelmBundle

Wrapper for Helm charts that is handled by Helm Controller. HelmBundle tracks what Helm charts must be installed on a MOSK cluster.
