Changes to an existing runner in puppet config aren't applied

[EmteZogaf]

Currently it's only checked, if the config.toml contains a runner with the same description as specified in the puppet configuration, but not if its parameters match the puppet config.

Instead of using grep, awk or similar to find matching lines in the config.toml, I think, the best solution would be to use a config.toml-runner template and use puppetlabs-concat to join single runner-templates in the final config.toml. This rebuilds the config on every puppet run and the changes are automatically picked up by gitlab-ci-multi-runner.

But this would need some bigger refactoring.

I gave it a try but hit the wall because the runner token is unknown when filling the config template. And it's not possible to register a new runner via adding it to the config.toml.

We could use file_line for this: https://forge.puppet.com/puppetlabs/stdlib#file_line

However it isn't something I've run into as a problem in my environment yet.

This would be indeed a great improvement.
