OpenSUSE has recently announced the release of a new version of their distribution called OpenSUSE Leap Micro 6.1. This updated distribution is specifically designed for creating microservices and can be used as a basic system for virtualization platforms and container insulation. The installation assemblies are available for architectures x86_64 and ARM64 (Aarch64), along with ready-made systemic images for virtualization systems. For those interested, downloads are available on the OpenSUSE website.
OpenSUSE Leap Micro is based on the project technologies of MicroOS and is considered a commercial product known as Linux Enterprise Micro. Unlike other distributions, OpenSUSE Leap Micro does not come with a graphic interface. Instead, users can utilize the Web interface Cockpit for system control through the browser. Other tools such as cloud-init and combustion can be used for setting up configurations during the first boot. Users also have the option to switch from OpenSUSE Leap Micro to SUSE SLE Micro, allowing for extended support or certification with existing configurations.
One of the key features of OpenSUSE Leap Micro is the mechanism of atomic installation of updates, which are loaded and used automatically. This feature allows for the system to rollback to the previous state in case of problems after applying updates. Additionally, live patching is available for updating the Linux kernel without the need to restart the system.
The root section is mounted in read-only mode to ensure stability during operation. Integrated support for Podman/CRI-O and Docker systems is included for launching insulated containers. The distribution also utilizes the SLFO (SUSE Linux Framework One) for managing the Host OS environment and recommends running applications and components in separate containers or virtual machines on top of the Host OS.
Overall, OpenSUSE Leap Micro 6.1 offers a streamlined and efficient solution for creating microservices and managing virtualization platforms. For more information on the new release, you can visit the official OpenSUSE website.
