Mirantis OpenStack for Kubernetes

What Mirantis OpenStack for Kubernetes is

Mirantis OpenStack for Kubernetes (MOSK) combines Kubernetes cluster management with OpenStack APIs to build self-hosted cloud infrastructure. It automates lifecycle routines such as cluster updates and upgrades, while its management layer handles bare-metal provisioning and Kubernetes cluster management. A typical cluster can include Keystone, Nova, Glance, Cinder, Neutron and Designate. Networking options include Neutron with OVS, Neutron with OVN and OpenSDN. Storage supports containerized Ceph plus integrations with Pure Storage, HPE and Dell. StackLight supplies logging, monitoring and alerting across the cluster stack. Keystone provides authentication, distributed multi-tenant authorization and federation support. Security guidance addresses access policies, audit logs, credentials, data protection, firewalls and compliance. MOSK 26.2 added DISA STIG support for host operating systems of MOSK and management clusters. The supported Gazpacho OpenStack release has scheduled LTS updates through Q3 2028. MOSK is open source and free, but a license is required. When that license expires, new and existing cluster API operations and updates are blocked, while existing workloads remain unaffected.

Who it suits

It suits teams building self-hosted infrastructure that combines Kubernetes operations with OpenStack APIs. Organizations needing bare-metal provisioning, multi-tenant access controls and enterprise storage integrations may fit its listed capabilities.

Limits

When a MOSK license expires, new and existing cluster API operations and updates are blocked. Existing workloads remain unaffected.

Getting started

1. Visit the Mirantis MOSK website
2. Deploy MOSK in a self-hosted Linux environment
3. Provision bare-metal infrastructure and Kubernetes clusters
4. Select Neutron with OVS, Neutron with OVN, or OpenSDN networking
5. Configure Ceph or a supported enterprise storage integration
6. Set up StackLight logging, monitoring, and alerting
7. Obtain and maintain the required MOSK license

Verdict

MOSK brings OpenStack services, Kubernetes management and infrastructure automation into a self-hosted platform. Its storage, networking, monitoring and security options are extensive, but license renewal is operationally important.
