Adds a column to help the operator see if they configured HRA.Spec.ScheduledOverrides correctly, in a form of "next override schedule recognized by the controller":
```
$ k get horizontalrunnerautoscaler
NAME MIN MAX DESIRED SCHEDULE
actions-runner-aos-autoscaler 0 5 0
org 0 5 0 min=0 time=2021-05-21 15:00:00 +0000 UTC
```

This fixes human-readable output of `kubectl get` on `runnerdeployment`, `runnerreplicaset`, and `runner`.
Most notably, CURRENT and READY of runner replicasets are now computed and printed correctly. Runner deployments now have UP-TO-DATE and AVAILABLE instead of READY so that it is consistent with columns of K8s deployments.
A few fixes has been also made to runner deployment and runner replicaset controllers so that those numbers stored in Status objects are reliably updated and in-sync with actual values.
Finally, `AGE` columns are added to runnerdeployment, runnerreplicaset, runnner to make that more visible to users.
`kubectl get` outputs should now look like the below examples:
```
# Immediately after runnerdeployment updated/created
$ k get runnerdeployment
NAME DESIRED CURRENT UP-TO-DATE AVAILABLE AGE
example-runnerdeploy 0 0 0 0 8d
org-runnerdeploy 5 5 5 0 8d
# A few dozens of seconds after update/create all the runners are registered that "available" numbers increase
$ k get runnerdeployment
NAME DESIRED CURRENT UP-TO-DATE AVAILABLE AGE
example-runnerdeploy 0 0 0 0 8d
org-runnerdeploy 5 5 5 5 8d
```
```
$ k get runnerreplicaset
NAME DESIRED CURRENT READY AGE
example-runnerdeploy-wnpf6 0 0 0 61m
org-runnerdeploy-fsnmr 2 2 0 8m41s
```
```
$ k get runner
NAME ENTERPRISE ORGANIZATION REPOSITORY LABELS STATUS AGE
example-runnerdeploy-wnpf6-registration-only actions-runner-controller/mumoshu-actions-test Running 61m
org-runnerdeploy-fsnmr-n8kkx actions-runner-controller ["mylabel 1","mylabel 2"] 21s
org-runnerdeploy-fsnmr-sq6m8 actions-runner-controller ["mylabel 1","mylabel 2"] 21s
```
Fixes#490
`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
This adds the initial version of ScheduledOverrides to HorizontalRunnerAutoscaler.
`MinReplicas` overriding should just work.
When there are two or more ScheduledOverrides, the earliest one that matched is activated. Each ScheduledOverride can be recurring or one-time. If you have two or more ScheduledOverrides, only one of them should be one-time. And the one-time override should be the earliest item in the list to make sense.
Tests will be added in another commit. Logging improvements and additional observability in HRA.Status will also be added in yet another commits.
Ref #484
Adds two types `RecurrenceRule` and `Period` and one function `MatchSchedule` as the foundation for building the upcoming ScheduledOverrides feature.
Ref #484
- 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
Previously any non-go changes resulted in `make docker-build` rerunning time-consufming `go build`. This fixes that by adding clearly unnecessary files .dockerignore
- 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)
