bootc-mke3 is an integrated container orchestration platform that is powered by an immutable Rocky Linux operating system, offering next-level security and reliability.
This repository contains a collection of tool, utilities and guides for managing and operating with bootc-mke3. These tools support operations, automation, and configuration for secure and scalable container environments.
Installation covers everything from provisioning bare infrastructure to a running MKE cluster: registry and machine requirements, provisioning with Terraform (vSphere/AWS) or manually, running the Ansible installer, and the controllers deployed by default post-install. See the full guide at Installation guide documentation pages.
Mirantis publishes bootc-mke3 assets on the Releases page. That is the place to find them; this repository does not list download links or versions. Each release notes the MCR and MKE versions it contains, the OCI image references (registry.mirantis.com/bootc-mke3/..., including the exact build tag), download links for the bootable ISO and QCOW2 images, the versions of the preloaded controllers, and the SBOM/CVE reports (see Verify bootc-mke3 image signatures). Not every release covers every platform; check the Platforms line of the release you pick.
Note
Simple ISO edition is used mostly for demo/test purposes. For production-grade clusters consider using Generic ISO. See ISO editions.
Operations covers day-2 tasks on a running cluster: upgrading it (via the ClusterUpgrade CR or the Ansible exception path), adding machines with no-touch join, accessing it with the MKE client bundle, and securing it. See the full guide at Operations guide documentation pages.
