`HRA.Spec.ScaleTargetRef.Kind` is added to denote that the scale-target is a RunnerSet.
It defaults to `RunnerDeployment` for backward compatibility.
```
apiVersion: actions.summerwind.dev/v1alpha1
kind: HorizontalRunnerAutoscaler
metadata:
name: myhra
spec:
scaleTargetRef:
kind: RunnerSet
name: myrunnerset

This option expose internally some `KUBERNETES_*` environment variables
that doesn't allow the runner to use KinD (Kubernetes in Docker) since it will
try to connect to the Kubernetes cluster where the runner it's running.
This option it's set by default to `true` in any Kubernetes deployment.

* feat: RunnerSet backed by StatefulSet
Unlike a runner deployment, a runner set can manage a set of stateful runners by combining a statefulset and an admission webhook that mutates statefulset-managed pods with required envvars and registration tokens.

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.

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
```
Ref https://github.com/actions-runner-controller/actions-runner-controller/issues/484
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
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 `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
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.

Enable the user to set a limit size on the volume of the runner to avoid some runner pod affecting other resources of the same cluster
Co-authored-by: Yusuke Kuoka <ykuoka@gmail.com>
We occasionally encountered those errors while the underlying RunnerReplicaSet is being recreated/replaced on RunnerDeployment.Spec.Template update. It turned out to be due to that the RunnerDeployment controller was waiting for the runner pod becomes `Running`, intead of the new replacement runner to have registered to GitHub. This fixes that, by trying to Runner.Status.Phase to `Running` only after the runner in the runner pod appears to be registered.
A side-effect of this change is that runner controller would call more "ListRunners" GitHub Actions API. I've reviewed and improved the runner controller code and Runner CRD to make make the number of calls minimum. In most cases, ListRunners should be called only twice for each runner creation.
This allows you to trigger autoscaling depending on check_run names(i.e. actions job names). If you are willing to differentiate scale amount only for a specific job, or want to scale only on a specific job, try this.
* add replicaCount
* Add authSecret.existingSecret
* set image.tag null by default
* implement ingress for githubwebhook server
* fix deprecated and secretName template
* backward compat .authSecret.enabled
* existingSecret for github webhook secret
* use secretName template
* set default secret names
* do not use app version based image tag
* create and name variable for secrets
