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.

Host operating system configuration

TechPreview

Important

The cloud operator takes all risks and responsibility for module execution on cluster machines. For any questions, contact Mirantis support.

The host operating system (OS) configuration API extends configuration management of baremetal-based clusters and machines after initial deployment. The feature allows managing the operating system of a bare metal host granularly using modules without rebuilding the node from scratch. Such approach prevents workload evacuation and significantly reduces configuration time.

The host OS configuration API does not limit the cloud operator’s ability to configure machines in any way, making the operator responsible for day-2 adjustments.

This section provides guidelines for MOSK or custom modules that are used by the HostOSConfiguration and HostOSConfigurationModules custom resources designed for MOSK clusters.

• Host OS configuration management workflow
• Global recommendations for implementation of custom modules
• Format and structure of a module package
• Modules provided by MOSK
• HostOSConfiguration and HostOSConfigurationModules concepts
• Internal API for host OS configuration management
• Add a custom module to a MOSK deployment
