Mirantis Releases The First Significant Update To Their Container Runtime In Two Years


New features, enhancements, bug fixes, and security updates are have been added in MCR 23.0.

In conjunction with a revitalised Moby project, the open source container framework, Mirantis, which frees developers to write their most important code, today launched the first major version of the Mirantis Container Runtime (MCR) in two years. This update to MCR’s features, functionality, bug patches, and security measures aims to increase MCR’s dependability, effectiveness, and security.

Moby, along with other open source projects, is the upstream project for the Mirantis Container Runtime, Docker, and Docker Engine. Users can now switch between the supported, enterprise-grade Mirantis Container Runtime and the community-developed, open source Moby software by using MCR 23.0, which matches the upstream version numbers of the Moby project. The Moby project-compliant Mirantis Container Runtime (MCR) offers a small, safe, and highly available environment for executing containerized applications that is compatible with the majority of Docker-compatible workflow, development, and workflow tools, platforms, and services.

To make it simpler to manage storage resources across container orchestration systems, MCR 23.0 and Moby add experimental support for Container Storage Interface (CSI) drivers in Swarm, which is currently only intended for development purposes. Developers can benefit from the same storage plugins that Kubernetes supports by using CSI drivers, which are the same storage drivers that Kubernetes utilises.

It is anticipated that a whole ecosystem of persistent storage backends would be made available as the CSI-compliant implementation in Swarm develops. As its implementation matures, Mirantis actively collaborates with the Moby development community to fix any flaws and add any functionality that are still lacking. Moreover, Oracle Linux 8, RHEL 9, and Windows Server 2022 are now supported by MCR 23.0.

MCR makes managing containerized apps and infrastructure easier while also enhancing their general performance and security by utilising the power of Moby and providing useful features and hardening. By relieving developers of the responsibility for managing infrastructure, MCR and Moby let them to concentrate on writing their most useful code, which in turn helps to quicken development cycles, lower expenses, and raise the general calibre of applications.
