Mirantis OpenStack for Kubernetes
Mirantis OpenStack for Kubernetes, or MOSK, combines Kubernetes cluster management with OpenStack APIs for building self-hosted cloud infrastructure.
What Mirantis OpenStack for Kubernetes is
Mirantis OpenStack for Kubernetes, or MOSK, combines Kubernetes cluster management with OpenStack APIs for building 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 choices include Neutron with OVS, Neutron with OVN, and OpenSDN. Storage supports containerized Ceph plus enterprise integrations from 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, credential management, data protection, firewalls, and compliance. MOSK 26.2 introduced DISA STIG support for host operating systems of MOSK and management clusters. Its supported Gazpacho OpenStack release has scheduled LTS updates through Q3 2028. MOSK is open source and free, but a license is required; after expiration, new and existing cluster API operations and updates are blocked while workloads remain unaffected.
Good
