- Adds `ephemeral` option to `runner.spec`
```
....
template:
spec:
ephemeral: false
repository: mumoshu/actions-runner-controller-ci
....
```
- `ephemeral` defaults to `true`
- `entrypoint.sh` in runner/Dockerfile modified to read `RUNNER_EPHEMERAL` flag
- Runner images are backward-compatible. `--once` is omitted only when the new envvar `RUNNER_EPHEMERAL` is explicitly set to `false`.
Resolves#457
This is an attempt to support scaling from/to zero.
The basic idea is that we create a one-off "registration-only" runner pod on RunnerReplicaSet being scaled to zero, so that there is one "offline" runner, which enables GitHub Actions to queue jobs instead of discarding those.
GitHub Actions seems to immediately throw away the new job when there are no runners at all. Generally, having runners of any status, `busy`, `idle`, or `offline` would prevent GitHub actions from failing jobs. But retaining `busy` or `idle` runners means that we need to keep runner pods running, which conflicts with our desired to scale to/from zero, hence we retain `offline` runners.
In this change, I enhanced the runnerreplicaset controller to create a registration-only runner on very beginning of its reconciliation logic, only when a runnerreplicaset is scaled to zero. The runner controller creates the registration-only runner pod, waits for it to become "offline", and then removes the runner pod. The runner on GitHub stays `offline`, until the runner resource on K8s is deleted. As we remove the registration-only runner pod as soon as it registers, this doesn't block cluster-autoscaler.
Related to #447
* Fix acceptance helm test not using newly built controller image
* Locally build runner image instead of pulling it
* Revert runner controller image pull policy to always
and add a line to the test deployment to use IfNotPresent
* Change runner repository from summerwind/action-runner to the owner of actions-runner-controller.
Also fix some Makefile formatting.
* Undo renaming acceptance/pull to docker-pull
* Some env var cleanup
Rename USERNAME to DOCKER_USER(is still used for github too tho)
Add RUNNER_NAME var(defaults to $DOCKER_USER/actions-runner)
Add TEST_REPO(defaults to $DOCKER_USER/actions-runner-controller)
Changes:
- Switched to use `jq` in startup.sh
- Enable docker registry mirror configuration which is useful when e.g. avoiding the Docker Hub rate-limiting
Check #478 for how this feature is tested and supposed to be used.
Images for `actions-runner:v${VERSION}` and `actions-runner:latest` tags are upgraded to Ubuntu 20.04.
If you would like not to upgrade Ubuntu in the runner image in the future, migrate to new tags suffixed with `-ubuntu-20.04` like`actions-runner:v${VERSION}-ubuntu-20.04`.
We also keep publishing the existing Ubuntu 18.04 images with new `actions-runner:v${VERSION}-ubuntu-18.04` tags. Please use it when it turned out that you had workflows dependent on Ubuntu 18.04.

Prevents arguments from being split when e.g. the RUNNER_GROUP variable contains spaces (which is legit. One can create such groups in GitHub).
I've seen that all workers with group names that contain no spaces can register successfully, while all workers with groups that contain spaces will not register.
Furthermore, I suppose also other chars can be used here to inject arbitrary commands in an unsupported way via e.g. pipe symbol.
Quoting the vars correctly should prevent that and allow for e.g. group names and runner labels with spaces and other bash reserved characters.
* so far, runner group parameter is only set for runners with org scope
* now set group for enterprise runners as well
* removed null check for org scope as either org or enterprise will be set
* bug-fix: patched dir owned by runner
* always build with latest runner version
* Revert "always build with latest runner version"
This reverts commit e719724ae9fe92a12d4a087185cf2a2ff543a0dd.
* Also patch dindrunner.Dockerfile

It turned out previous versions of runner images were unable to run actions that require `AGENT_TOOLSDIRECTORY` or `libyaml` to exist in the runner environment. One of notable examples of such actions is [`ruby/setup-ruby`](https://github.com/ruby/setup-ruby).
This change adds the support for those actions, by setting up AGENT_TOOLSDIRECTORY and installing libyaml-dev within runner images.
* runner/controller: Add externals directory mount point
* Runner: Create hack for moving content of /runner/externals/ dir
* Externals dir Mount: mount examples for '__e/node12/bin/node' not found error
* Adds RUNNER_GROUP argument to the runner registration
Adds the ability to register a runner to a predefined runner_group
Resolves#137
* Update README with runner group example
- Updates the README with instructions of how to add the runner to a
group
- Fix code fencing for shell and yaml blocks in the README
- Use consistent bullet points (dash not asterisk)
Adding multi-arch image support for `arm64` and `amd64`. This uses dockers new `buildx` feature, to enable further architectures more work will be required to update the `runner/Dockerfile` file to pull architecture-specific releases.
The Makefile targets really should only be used for local testing and not for release, additional work to appropriately tag the release images may need to be added but for now, I've not added that logic.
Fixes: #86

* Use self update ready entrypoint
* Add --once support for runsvc.sh
Run `cd runner; NAME=$DOCKER_USER/actions-runner TAG=dev make docker-build docker-push`,
`kubectl apply -f release/actions-runner-controller.yaml`,
then update the runner image(not the controller image) by updating e.g. `Runner.Spec.Image` to `$DOCKER_USER/actions-runner:$TAG`, for testing.
