Background¶

The Python based docker-compose was deprecated upstream in July and was never supported in SLES. Now docker-suppose is in version 2 and based on go - https://github.com/docker/compose

This new docker-compose will be part of SLE Micro 6.0 and should be tested - First on Tumbleweed/MicroOS and then on SLEM 6.0 (Factory first).

docker-compose supports docker and podman, so we need to test it against both backends. This tool is called via docker compose or podman compose. Don't get confused by the name - podman compose calls docker-compose.

To counter some of the confusion, it can be that the package will be renamed to compose in the future.

Action items¶

• Disable/remove the old tests for docker-compose which are not supported. They are dead weight, that we don't want to have when starting to work on the new ones
• Check what the status of docker-compose is in Tumbleweed. If this is v2 already, then we can start to upgrade the existing test module. Otherwise we need to wait
• Given that the old docker-compose was never supported, we can start directly in upgrading the existing test module to the new v2
• Upgrade the old test runs to use the v2 of docker-compose
• Run the docker-compose test for docker and podman
• Rename the docker-compose test to compose to avoid some confusion
