Sets the privileged flag to false if SELinuxOptions are present/defined. This is needed because containerd treats SELinux and Privileged controls as mutually exclusive. Also see https://github.com/containerd/cri/blob/aa2d5a97c/pkg/server/container_create.go#L164.
This allows users who use SELinux for managing privileged processes to use GH Actions - otherwise, based on the SELinux policy, the Docker in Docker container might not be privileged enough.

This allows using the `runtimeClassName` directive in the runner's spec.
One of the use-cases for this is Kata Containers, which use `runtimeClassName` in a pod spec as an indicator that the pod should run inside a Kata container. This allows us a greater degree of pod isolation.
`PercentageRunnersBusy`, in combination with a secondary `TotalInProgressAndQueuedWorkflowRuns` metric, enables scale-from-zero for PercentageRunnersBusy.
Please see the new `Autoscaling to/from 0` section in the updated documentation about how it works.
Resolves#522
- 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
- You can now use `make acceptance/run` to run only a specific acceptance test case
- Add note about Ubuntu 20.04 users / snap-provided docker
- Add instruction to run Ginkgo tests
- Extract acceptance/load from acceptance/kind
- Make `acceptance/pull` not depend on `docker-build`, so that you can do `make docker-build acceptance/load` for faster image reload
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.
* chore: adding Helm app version back
* chore: removing redundant values entry
* chore: bumping to newer version
* chore: bumping app version to latest

* Cache docker images locally
Cache dind, runner, and kube-rbac-proxy docker image on the host and copy onto the kind node instead of downloading it to the node directly.
* Also cache certmanager docker images
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.
