Harvester Base OS

Dev/Daily Build and Publish

The base OS for Harvester, powered by cOS-toolkit.

Branch

  • sle-micro: means the development branch.
  • harvester-v1.2.x: means the v1.2.x stable branch.
  • harvester-v1.1.x: means the v1.1.x stable branch.

Mostly we will develop on the sle-micro branch and backport what we needed to the stable branch.

How-Tos

Update luet repository

We pinned the luet repository version to ensure the version of applications installed via luet remain intact if we only want to upgrade OS. To update the repository:

  1. Visit http://quay.io/costoolkit/releases-green
  2. Filter tags with -repository.yaml
  3. Look for the tag with the latest date, e.g. 20220420151313-repository.yaml
  4. Update luet repository version with this tag
  5. Build the Base OS container with ./scripts/build, and the container should have used the repository you specified

If you already have a working Base OS container but you are not sure which repository it is using, verify its luet "Revision" by running command luet repo list:

cos
  cOS official
  Revision 287 - 2022-04-20 15:13:13 +0000 UTC

After you pinned the repository, run command luet repo update, and you will see the revision of the pinned repository:
