This prevents issues I'm seeing with the hydra I'm running on my laptop.
Every time I reboot it I see eval errors like this:
```
error fetching latest change from git repo at `https://github.com/nixos/nixpkgs.git':
fatal: unable to access 'https://github.com/nixos/nixpkgs.git/': Could not resolve host: github.com
```
This is because the evaluator already starts before the network is
actually online. It should wait until the network is fully online before
starting evaluation to prevent evaluation errors like above.
Nothing the script `config.sh` does prior to the final call to
`Runner.Listener configure` is relevant for the systemd service.
Particularly, we don't need (nor want) any of the artifacts the `env.sh`
script creates.
We’ve been having trouble figuring out which kind of token to use and
why our setup would break every few system updates.
This should clarify which options there are, and which ones lead to
better results.
Ideally there would be a manual section that has a step-by-step guide
on how to set up the github runner, with screenshots and everything.
Purge contents of `workDir` as root to also allow the removal of files
marked as read-only. It is easy to create read-only files in `workDir`,
e.g., by copying files from the Nix store.
The `serviceOverrides` module option is commonly used to loosen the
systemd unit's hardening. This commit merges the `serviceConfig` with
`mkMerge` instead of using the update operator `//` which discards all
existing values on conflict. To avoid a breaking change which requires
defining each option with a higher priority (e.g., through `mkForce`),
this commit prefixes hardening values with `mkDefault`.
Notable exceptions are list hardening options which use `mkBefore`
instead of `mkDefault`. This allows for easy extension of the existing
settings. Resetting redefinitions are still possible through `mkForce`.
when you register a runner with spaces in its name (possible if you use 'description' option) then the runners never get unregistered because our bash scripts assume no space in names.
This solves the issue
Retreiving the fullname of the runner via `gitlab-runner list` got surprisingly hard between lazy-capture issues and `gitlab-runner list` displaying invisible (CSI) characters that break the regex etc.
Which is why I fell back on the pseudo-json format.
This PR adds the hash in the name, which allows to keep both the
stateless aspect of the module while allowing for a freeform name.
I found using bash associative arrays easier to use/debug than the current
approach.
On some occasions, the GitHub runner service encounters errors which are
deemed retryable but result in the runner's termination. To signal a
retryable error, the runner exits with status code 2:
https://github.com/actions/runner/blob/40ed7f8/src/Runner.Common/Constants.cs#L146
To account for that behavior, this commit sets
`RestartForceExitStatus=2` which results in a service restart regardless
of using an ephemeral runner or not.
The new defaults allows jenkins-job-builder to reload the configuration
out-of-the-box, whereas the previous defaults required users to manually
reload/restart jenkins, or configure accessUser/accessTokenFile
themselves.
(If `extraJavaOptions = [ "-Djenkins.install.runSetupWizard=false" ]`
then the initial admin user is *not* created and you have to use JCasC
or something else to bootstrap.)
