openSUSE Leap Micro 5.5

Leap Micro is an ultra-reliable, lightweight operating system built for containerized and virtualized workloads.

This community version is based on SUSE Linux Enterprise Micro, which leverages the enterprise hardened security and compliance components of SUSE Linux Enterprise. This merging of technologies provides for a modern, immutable and developer-friendly OS platform.

Leap Micro 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 Leap Micro 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.

Choosing Which Media to Download

The new self-install image is recommended for all who do not require custom partitioning and can boot from USB. A simple self-install wizard dumps a preconfigured image to the drive, and grows the partition to the size of the disk.
Users with Raspberry Pi and similar without usb-boot support can directly write the pre-conifgured image to the SD card. Users seeking more control over deployment are adviced to use Combustion.
A demo of a combustion based deployment can be seen here.
The jeos-firstboot will greet those who did not configure their system by using Combustion.

The Offline ISO Image should be use by those who require custom partitioning.

Verify Your Download Before Use

Many applications can verify the checksum of a download. To verify your download can be important as it verifies you really have got the ISO file you wanted to download and not some broken version.

For each ISO, we offer a checksum file with the corresponding SHA256 sum.

For extra security, you can use sha256sum to verify who signed those .sha256 files.

It should be AD48 5664 E901 B867 051A B15F 35A2 F86E 29B7 00A4
