Container Runtime for Windows, Mirantis Container Runtime, Docker Container Runtime, Docker Engine

If your teams are already building and managing applications with Docker, you can promote those workloads to production without needing to retool or migrate. Mirantis Container Runtime (formerly Docker Engine - Enterprise) is fully compatible with Docker-based workflows and toolchains, providing a seamless path from development to production. Developers can continue using the same CLI, Dockerfiles, and APIs they already know, while IT can seamlessly promote those workloads into production with the assurance of an Enterprise Support agreement with guaranteed SLAs.

MCR, built on CNCF Docker Moby, is purpose-built for running containers at scale in production. It offers tested and validated releases across a broad set of operating systems, with robust CVE patching and bug fixes to ensure workload stability. MCR also enables hybrid and distributed cloud strategies by supporting the broadest range of platforms in the industry while meeting strict compliance standards.

Mirantis acquired Docker Enterprise in 2019, and since then has been contributing upstream to Docker Moby and related technologies. Today, MCR provides enterprise-ready container infrastructure that aligns with open standards, enabling customers to run Docker-based applications reliably in mission-critical environments.

The latest MCR 29 plan introduces a number of important platform enhancements designed to improve operability, developer experience, and production readiness. These include improved IPv6 networking support, device code login support for Docker Hub, the containerd image store as the default backend for new installations, enhanced IP address management visibility, additional Docker Swarm service options, and API and SDK improvements for third-party integrations.

Key Features include:

• Security: AppArmor application-level access control, SELinux mandatory access control (MAC), FIPS 140-2 validated encryption, image signature verification, and support for sandboxed and isolated container runtimes such as Kata and gVisor
• Performance: Optimized architecture with minimal resource overhead, fast container startup for efficient deployment and scaling
• Ease of Use: Intuitive Docker CLI and support for Docker Swarm container orchestration in addition to Kubernetes
• Multi-Cloud Interoperability: Support for multiple cloud platforms and operating systems, giving customers seamless portability with consistent management
• AI Workload Support: Native AI container support, enhanced GPU Support with Container Device Interface (CDI) to integrate different accelerators and device types
• Modern Platform Enhancements in MCR 29: Improved IPv6 stability, modernized image management with containerd image store, enhanced network IPAM visibility, new Swarm service controls, and API/SDK updates for developers
