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

Starting with MOSK 25.2, the MOSK documentation set will cover all product layers, including MOSK management (formerly MCC). This means everything you need will be in one place. The separate MCC documentation site will be retired, so please update your bookmarks for continued easy access to the latest content.

Configure initial resource oversubscription¶

Available since MOSK 23.1

MOSK enables you to configure initial oversubscription through the OpenStackDeployment custom resource. For configuration details and oversubscription considerations, refer to Configuring initial resource oversubscription.

By default, the following values are applied:

8.0 for the number of CPUs
1.6 for the disk space
1.0 for the amount of RAM

Note

In MOSK 22.5 and earlier, the effective default value of RAM allocation ratio is 1.1.

Changing oversubscription configuration after deployment will only affect the newly added compute nodes and will not change oversubscription for already existing compute nodes. You can change oversubscription for existing compute nodes through the placement API as described in Change oversubscription settings for existing compute nodes.
