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.
MicroOS offers an offline image. The main difference between the offline and self-install/raw images are that the offline image has an installer. Raw and self-install allows for customization via combustion or manually in the image after it is written to the disk. There is an option for a real-time kernel.
Try MicroOS in VMs running on either Xen or KVM. Using a Raspberry Pi or other System on Chip hardware may use the preconfigured image together with the Combustion functionality for the boot process. Both preconfigured and self-installed images are intended to be used with Combustion written to a USB, which is driven to allow configuration on any first boot, with the option for default password protected changes.

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
Unique
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.
Flexible
- No new package format is needed, use standard openSUSE RPMs
- No size limitation, neither for partitions nor the operating system
- Easy to enhance
Rollback
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
Workloads
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
Debugging Toolbox Container
- Launches privileged container
- Root filesystem available below
/media/root
- zypper to install the necessary tools, available without reboot
- Persistent between usages
