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

Now, 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.

Delete a compute node

The OpenStack-related metadata is automatically removed during the graceful machine deletion through the MOSK management console. For the procedure, refer to Delete a cluster machine.

During the graceful machine deletion, the OpenStack Controller (Rockoon) performs the following operations:

• Disables the OpenStack Compute and Block Storage services on the node to prevent further scheduling of workloads to it.

• Verifies if any resources are present on the node, for example, instances and volumes. By default, the OpenStack Controller blocks the removal process until the resources are removed by the user. To adjust this behavior to the needs of your cluster, refer to OpenStack Controller configuration.

• Removes OpenStack services metadata including compute services, Neutron agents, and volume services.

Caution

You cannot collocate the OpenStack compute node with other cluster components, such as Ceph. If done so, refer to the removal steps of the collocated components when planning the maintenance window.
