openSUSE MicroOS

Micro Service OS providing Transactional (Atomic) Updates upon a read-only btrfs root filesystem

Designed to host container workloads with automated administration & patching. Installing openSUSE MicroOS you get a quick, small environment for deploying Containers, or any other workload that benefits from Transactional Updates. As rolling release distribution the software is always up-to-date.



Is predictable

  • Is not altered during runtime
  • Will run the same artifacts consistently on every boot

Is scalable

  • Eliminates efforts in configuring individual instances during runtime
  • Can be rolled out easily repeatedly with predictable outcome

Is reliable

  • Automated recovery from faulty updates

Atomic Updates

Transactional Updates


By using btrfs with snapshots MicroOS uses a very space efficient way to store the file system’s history. All the configuration files in /etc are part of the snapshot and the rollback.


  • No new package format is needed, use standard openSUSE RPMs
  • No size limitation, neither for partitions nor the operating system
  • Easy to enhance


MicroOS is an Immutable OS, rollback is simple

  • Immutable: No changes on disk
  • Rollback by rebooting to an old BTRFS snapshot

Secure Updates

  • Get your updates via HTTPS
  • Packages and repositories are signed by our build system
  • Packages are verified
  • No updates are done in case of dependency conflicts
  • No waste of space: Filesystem snapshots get deleted in case of unsuccessful updates


Applications are installed in containers rather than the root filesystem:

  • Isolated from the core filesystem
  • Reduced ability for malicious applications to compromise the system
  • New installation without reboot
  • Update in atomic way possible (create new, kill old)
  • Easy rollback


Debugging Toolbox Container

  • Launches privileged container
  • Root filesystem available below /media/root
  • zypper to install the necessary tools, available without reboot
  • Persistent between usages

许多程序都可以验证下载文件的校验码。验证你下载的文件挺重要的, 因为它可以验证你是否真的撷取到了你想要下载的 ISO 文件而不是 一些损坏的版本。

针对每个 ISO,我们都提供了一个带有相应 SHA256 和的校验码文件。

出于额外的安全考虑,你可以使用 GPG 验证谁签发了这些 .sha256 文件。

它应为 22C0 7BA5 3417 8CD0 2EFE 22AA B88B 2FD4 3DBD C284
