setting the docker container MAC address

[sh-cau]

The actual gitlab runner is registered using gitlab-runner register --docker-mac-address AA:BB:CC:DD:EE:FF ..., which writes the mac address in the config.toml of the gitlab runner much like described in your second reference. Unfortunately, gitlab-runner exec ignores this configuration entirely (but it doesn't when its being called by GitLab).

You solution works, however, this requires me to adjust the .gitlab-ci.yaml everytime I want to test locally and this, in fact, is the reason I quit using gitlab-runner exec because with that you can't pass CI-specific environment variables, say, CI_JOB_TOKEN or CI_PIPELINE_SOURCE, which also leads to me having to rename these variables for the testing time.

We can add support for this, but my question is how do you then, plan to run this via the actual gitlab runnner ?

Maybe you can give the following a try?

#.gitlab-ci.yml
job:
  image: bash
  script:
    - ifconfig eth0 hw ether "AA:BB:CC:DD:EE:FF"
    - ip a show eth0
