The developers of the openSUSE project have released the atomically updatable distribution openSUSE Leap Micro 5.5, designed for creating microservices and as a base system for virtualization platforms and container isolation. Builds for x86_64 and ARM64 (Aarch64) architectures are available for download, provided both with an installer (Offline builds, size 2.1 GB) and as ready-to-boot images: 782 MB (pre-configured), 959 MB (with Real-Time kernel), and 1.1 GB. The images can run on Xen and KVM hypervisors or directly on hardware, including Raspberry Pi boards. <\/p>\n

The openSUSE Leap Micro distribution is based on the MicroOS project and is positioned as a community version of the commercial product SUSE Linux Enterprise Micro, differing in that it does not come with a graphical interface. For configuration, users can utilize the Cockpit web interface, which allows system management through a browser, the cloud-init toolkit for applying settings at each boot, or Combustion to set parameters during the first boot. Users are provided with tools for a quick switch from Leap Micro to SUSE SLE Micro \u2014 it is implied that one can initially implement a solution based on Leap Micro for free and, if extended support or certification is needed, migrate the existing configuration to the SUSE SLE Micro product. <\/p>\n

A key feature of Leap Micro is the atomic update mechanism, which automatically downloads and applies updates. Unlike atomic updates based on ostree and snap, used in Fedora and Ubuntu, openSUSE Leap Micro utilizes standard package management tools (the transactional-update utility) combined with Btrfs snapshot mechanisms (snapshots are used for atomic switching between the system state before and after installation of updates). In case of issues following the updates, the system can be rolled back to a previous state. Live patches are supported for updating the Linux kernel without rebooting and interrupting operations. <\/p>\n

The root filesystem is mounted in read-only mode and does not change during operation. To launch isolated containers, an integrated toolkit supporting the Podman\/CRI-O and Docker runtimes is included. The micro-edition of the distribution is used in the ALP (Adaptable Linux Platform) project to ensure the operation of the 'host OS' environment. In ALP, a stripped-down 'host OS' is proposed for hardware operation, while all user space applications and components are to be launched not in a mixed environment, but in separate containers or in virtual machines<\/a>, executed over the «host OS» and isolated from one another. <\/p>\n
