+# Release Note Template
+
+This is the template of actions-runner-controller's release notes.
+
+Whenever a new release is made, I start by manually copy-pasting this template onto the GitHub UI for creating the release.
+
+I then walk-through all the changes, take sometime to think abount best one-sentence explanations to tell the users about changes, write it all,
+and click the publish button.
+
+If you think you can improve future release notes in any way, please do submit a pull request to change the template below.
+
+Note that even though it looks like a Go template, I don't use any templating to generate the changelog.
+It's just that I'm used to reading and intepreting Go template by myself, not a computer program :)
+
+**Title**:
+
+```
+v{{ .Version }}: {{ .TitlesOfImportantChanges }}
+```
+
+**Body**:
+
+```
+**CAUTION:** If you're using the Helm chart, beware to review changes to CRDs and do manually upgrade CRDs! Helm installs CRDs only on installing a chart. It doesn't automatically upgrade CRDs. Otherwise you end up with troubles like #427, #467, and #468. Please refer to the [UPGRADING](charts/actions-runner-controller/docs/UPGRADING.md) docs for the latest process.

+## Contributing
+
+### Testing Controller Built from a Pull Request
+
+We always appreciate your help in testing open pull requests by deploying custom builds of actions-runner-controller onto your own environment, so that we are extra sure we didn't break anything.
+
+It is especially true when the pull request is about GitHub Enterprise, both GHEC and GHES, as [maintainers don't have GitHub Enterprise environments for testing](/README.md#github-enterprise-support).
+
+The process would look like the below:
+
+- Clone this repository locally
+- Checkout the branch. If you use the `gh` command, run `gh pr checkout $PR_NUMBER`
+- Run `NAME=$DOCKER_USER/actions-runner-controller VERSION=canary make docker-build docker-push` for a custom container image build
+- Update your actions-runner-controller's controller-manager deployment to use the new image, `$DOCKER_USER/actions-runner-controller:canary`
+
+Please also note that you need to replace `$DOCKER_USER` with your own DockerHub account name.
+
+### How to Contribute a Patch
+
+Depending on what you are patching depends on how you should go about it. Below are some guides on how to test patches locally as well as develop the controller and runners.
+
+When submitting a PR for a change please provide evidence that your change works as we still need to work on improving the CI of the project. Some resources are provided for helping achieve this, see this guide for details.
+
+#### Running an End to End Test
+
+> **Notes for Ubuntu 20.04+ users**
+>
+> If you're using Ubuntu 20.04 or greater, you might have installed `docker` with `snap`.
+>
+> If you want to stick with `snap`-provided `docker`, do not forget to set `TMPDIR` to
+> somewhere under `$HOME`.
+> Otherwise `kind load docker-image` fail while running `docker save`.
+> See https://kind.sigs.k8s.io/docs/user/known-issues/#docker-installed-with-snap for more information.
+
+To test your local changes against both PAT and App based authentication please run the `acceptance` make target with the authentication configuration details provided:
+
+```shell
+# This sets `VERSION` envvar to some appropriate value
+. hack/make-env.sh
+
+DOCKER_USER=*** \
+  GITHUB_TOKEN=*** \
+  APP_ID=*** \
+  PRIVATE_KEY_FILE_PATH=path/to/pem/file \
+  INSTALLATION_ID=*** \
+  make acceptance
+```
+
+**Rerunning a failed test**
+
+When one of tests run by `make acceptance` failed, you'd probably like to rerun only the failed one.
+
+It can be done by `make acceptance/run` and by setting the combination of `ACCEPTANCE_TEST_DEPLOYMENT_TOOL=helm|kubectl` and `ACCEPTANCE_TEST_SECRET_TYPE=token|app` values that failed (note, you just need to set the corresponding authentication configuration in this circumstance)
+
+In the example below, we rerun the test for the combination `ACCEPTANCE_TEST_DEPLOYMENT_TOOL=helm ACCEPTANCE_TEST_SECRET_TYPE=token` only:
+
+```shell
+DOCKER_USER=*** \
+  GITHUB_TOKEN=*** \
+  ACCEPTANCE_TEST_DEPLOYMENT_TOOL=helm
+  ACCEPTANCE_TEST_SECRET_TYPE=token \
+  make acceptance/run
+```
+
+**Testing in a non-kind cluster**
+
+If you prefer to test in a non-kind cluster, you can instead run:
+
+```shell
+KUBECONFIG=path/to/kubeconfig \
+  DOCKER_USER=*** \
+  GITHUB_TOKEN=*** \
+  APP_ID=*** \
+  PRIVATE_KEY_FILE_PATH=path/to/pem/file \
+  INSTALLATION_ID=*** \
+  ACCEPTANCE_TEST_SECRET_TYPE=token \
+  make docker-build acceptance/setup \
+       acceptance/deploy \
+       acceptance/tests
+```
+
+#### Developing the Controller
+
+Rerunning the whole acceptance test suite from scratch on every little change to the controller, the runner, and the chart would be counter-productive.
+
+To make your development cycle faster, use the below command to update deploy and update all the three:
+
+```shell
+# Let assume we have all other envvars like DOCKER_USER, GITHUB_TOKEN already set,
+# The below command will (re)build `actions-runner-controller:controller1` and `actions-runner:runner1`,
+# load those into kind nodes, and then rerun kubectl or helm to install/upgrade the controller,
+# and finally upgrade the runner deployment to use the new runner image.
+#
+# As helm 3 and kubectl is unable to recreate a pod when no tag change,
+# you either need to bump VERSION and RUNNER_TAG on each run,
+# or manually run `kubectl delete pod $POD` on respective pods for changes to actually take effect.
+
+# Makefile
+VERSION=controller1 \
+  RUNNER_TAG=runner1 \
+  make acceptance/pull acceptance/kind docker-build acceptance/load acceptance/deploy
+```
+
+If you've already deployed actions-runner-controller and only want to recreate pods to use the newer image, you can run:
+
+```shell
+# Makefile
+NAME=$DOCKER_USER/actions-runner-controller \
+  make docker-build acceptance/load && \
+  kubectl -n actions-runner-system delete po $(kubectl -n actions-runner-system get po -ojsonpath={.items[*].metadata.name})
+```
+
+Similarly, if you'd like to recreate runner pods with the newer runner image you can use the runner specific [Makefile](runner/Makefile) to build and / or push new runner images
+
+```shell
+# runner/Makefile
+NAME=$DOCKER_USER/actions-runner make \
+  -C runner docker-{build,push}-ubuntu && \
+  (kubectl get po -ojsonpath={.items[*].metadata.name} | xargs -n1 kubectl delete po)
+```
+
+#### Developing the Runners
+
+**Tests**
+
+A set of example pipelines (./acceptance/pipelines) are provided in this repository which you can use to validate your runners are working as expected. When raising a PR please run the relevant suites to prove your change hasn't broken anything.
+
+**Running Ginkgo Tests**
+
+You can run the integration test suite that is written in Ginkgo with:
+
+```shell
+make test-with-deps
+```
+
+This will firstly install a few binaries required to setup the integration test environment and then runs `go test` to start the Ginkgo test.
+
+If you don't want to use `make`, like when you're running tests from your IDE, install required binaries to `/usr/local/kubebuilder/bin`. That's the directory in which controller-runtime's `envtest` framework locates the binaries.
+
+```shell
+sudo mkdir -p /usr/local/kubebuilder/bin
+make kube-apiserver etcd
+sudo mv test-assets/{etcd,kube-apiserver} /usr/local/kubebuilder/bin/
+go test -v -run TestAPIs github.com/actions-runner-controller/actions-runner-controller/controllers
+```
+
+To run Ginkgo tests selectively, set the pattern of target test names to `GINKGO_FOCUS`.
+All the Ginkgo test that matches `GINKGO_FOCUS` will be run.
+
+```shell
+GINKGO_FOCUS='[It] should create a new Runner resource from the specified template, add a another Runner on replicas increased, and removes all the replicas when set to 0' \
+  go test -v -run TestAPIs github.com/actions-runner-controller/actions-runner-controller/controllers
+```
+
+#### Helm Version Bumps
+
+In general we ask you not to bump the version in your PR, the maintainers in general manage the publishing of a new chart.

+## Installation
+
+Troubeshooting runbooks that relate to ARC installation problems
+
+### InternalError when calling webhook: context deadline exceeded
+
+**Problem**
+
+This issue can come up for various reasons like leftovers from previous installations or not being able to access the K8s service's clusterIP associated with the admission webhook server (of ARC).
+
+```
+Internal error occurred: failed calling webhook "mutate.runnerdeployment.actions.summerwind.dev":
+Post "https://actions-runner-controller-webhook.actions-runner-system.svc:443/mutate-actions-summerwind-dev-v1alpha1-runnerdeployment?timeout=10s": context deadline exceeded
+```
+
+**Solution**
+
+First we will try the common solution of checking webhook leftovers from previous installations:
+
+1.  ```bash
+    kubectl get validatingwebhookconfiguration -A
+    kubectl get mutatingwebhookconfiguration -A
+    ```
+2.  If you see any webhooks related to actions-runner-controller, delete them:
+    ```bash
+    kubectl delete mutatingwebhookconfiguration actions-runner-controller-mutating-webhook-configuration
+    kubectl delete validatingwebhookconfiguration actions-runner-controller-validating-webhook-configuration
+    ```
+
+If that didn't work then probably your K8s control-plane is somehow unable to access the K8s service's clusterIP associated with the admission webhook server:
+1. You're running apiserver as a binary and you didn't make service cluster IPs available to the host network. 
+2. You're running the apiserver in the pod but your pod network (i.e. CNI plugin installation and config) is not good so your pods(like kube-apiserver) in the K8s control-plane nodes can't access ARC's admission webhook server pod(s) in probably data-plane nodes.
+
+
+Another reason could be due to GKEs firewall settings you may run into the following errors when trying to deploy runners on a private GKE cluster: 
+
+To fix this, you may either:
+
+1. Configure the webhook to use another port, such as 443 or 10250, [each of
+   which allow traffic by default](https://cloud.google.com/kubernetes-engine/docs/how-to/private-clusters#add_firewall_rules).
+
+   ```sh
+   # With helm, you'd set `webhookPort` to the port number of your choice
+   # See https://github.com/actions-runner-controller/actions-runner-controller/pull/1410/files for more information
+   helm upgrade --install --namespace actions-runner-system --create-namespace \
+                --wait actions-runner-controller actions-runner-controller/actions-runner-controller \
+                --set webhookPort=10250
+   ```
+
+2. Set up a firewall rule to allow the master node to connect to the default
+   webhook port. The exact way to do this may vary, but the following script
+   should point you in the right direction:
+
+   ```sh
+   # 1) Retrieve the network tag automatically given to the worker nodes
+   # NOTE: this only works if you have only one cluster in your GCP project. You will have to manually inspect the result of this command to find the tag for the cluster you want to target
+   WORKER_NODES_TAG=$(gcloud compute instances list --format='text(tags.items[0])' --filter='metadata.kubelet-config:*' | grep tags | awk '{print $2}' | sort | uniq)
+
+   # 2) Take note of the VPC network in which you deployed your cluster
+   # NOTE this only works if you have only one network in which you deploy your clusters
+   NETWORK=$(gcloud compute instances list --format='text(networkInterfaces[0].network)' --filter='metadata.kubelet-config:*' | grep networks | awk -F'/' '{print $NF}' | sort | uniq)
+
+   # 3) Get the master source ip block
+   SOURCE=$(gcloud container clusters describe <cluster-name> --region <region> | grep masterIpv4CidrBlock| cut -d ':' -f 2 | tr -d ' ')
+
+   gcloud compute firewall-rules create k8s-cert-manager --source-ranges $SOURCE --target-tags $WORKER_NODES_TAG  --allow TCP:9443 --network $NETWORK
+   ```
+
+### Invalid header field value
+
+**Problem**
+
+```json
+2020-11-12T22:17:30.693Z	ERROR	controller-runtime.controller	Reconciler error

+  "controller": "runner",

+}
+```
+
+**Solution**
+
+Your base64'ed PAT token has a new line at the end, it needs to be created without a `\n` added, either:
+* `echo -n $TOKEN | base64`
+* Create the secret as described in the docs using the shell and documented flags

+### Helm chart install failure: certificate signed by unknown authority
+
+**Problem**
+
+```

+```
+
+Apparently, it's failing while `helm` is creating one of resources defined in the ARC chart and the cause was that cert-manager's webhook is not working correctly, due to the missing or the invalid CA certficate.
+
+You'd try to tail logs from the `cert-manager-cainjector` and see it's failing with an error like:
+
+```

+Error: error registering secret controller: no matches for kind "MutatingWebhookConfiguration" in version "admissionregistration.k8s.io/v1beta1"
+```
+
+**Solution**
+
+Your cluster is based on a new enough Kubernetes of version 1.22 or greater which does not support the legacy `admissionregistration.k8s.io/v1beta1` API anymore, and your `cert-manager` is not up-to-date hence it's still trying to use the leagcy Kubernetes API.
+
+In many cases, it's not an option to downgrade Kubernetes. So, just upgrade `cert-manager` to a more recent version that does have have the support for the specific Kubernetes version you're using.
+
+See https://cert-manager.io/docs/installation/supported-releases/ for the list of available cert-manager versions.
+
+## Operations
+
+Troubeshooting runbooks that relate to ARC operational problems
+
+### Stuck runner kind or backing pod
+
+**Problem**
+
+Sometimes either the runner kind (`kubectl get runners`) or it's underlying pod can get stuck in a terminating state for various reasons. You can get the kind unstuck by removing its finaliser using something like this:
+
+**Solution**
+
+Remove the finaliser from the relevent runner kind or pod
+
+```
+# Get all kind runners and remove the finalizer
+$ kubectl get runners --no-headers | awk {'print $1'} | xargs kubectl patch runner --type merge -p '{"metadata":{"finalizers":null}}'
+
+# Get all pods that are stuck terminating and remove the finalizer
+$ kubectl -n get pods | grep Terminating | awk {'print $1'} | xargs kubectl patch pod -p '{"metadata":{"finalizers":null}}'
+```
+
+_Note the code assumes you have already selected the namespace your runners are in and that they 
+are in a namespace not shared with anything else_
+
+### Delay in jobs being allocated to runners
+
+**Problem**
+
+ARC isn't involved in jobs actually getting allocated to a runner. ARC is responsible for orchestrating runners and the runner lifecycle. Why some people see large delays in job allocation is not clear however it has been https://github.com/actions-runner-controller/actions-runner-controller/issues/1387#issuecomment-1122593984 that this is caused from the self-update process somehow.
+
+**Solution**
+
+Disable the self-update process in your runner manifests
+
+```yaml
+apiVersion: actions.summerwind.dev/v1alpha1
+kind: RunnerDeployment
+metadata:
+  name: example-runnerdeployment-with-sleep
+spec:
+  template:
+    spec:
+      ...
+      env:
+        - name: DISABLE_RUNNER_UPDATE
+          value: "true"
+```
+
+### Runner coming up before network available
+
+**Problem**
+
+If you're running your action runners on a service mesh like Istio, you might
+have problems with runner configuration accompanied by logs like:
+
+```
+....
+runner Starting Runner listener with startup type: service
+runner Started listener process
+runner An error occurred: Not configured
+runner Runner listener exited with error code 2
+runner Runner listener exit with retryable error, re-launch runner in 5 seconds.
+....
+```
+
+This is because the `istio-proxy` has not completed configuring itself when the
+configuration script tries to communicate with the network.
+
+More broadly, there are many other circumstances where the runner pod coming up first can cause issues.
+
+**Solution**<br />
+
+> Added originally to help users with older istio instances.
+> Newer Istio instances can use Istio's `holdApplicationUntilProxyStarts` attribute ([istio/istio#11130](https://github.com/istio/istio/issues/11130)) to avoid having to delay starting up the runner.
+> Please read the discussion in [#592](https://github.com/actions-runner-controller/actions-runner-controller/pull/592) for more information.
+
+You can add a delay to the runner's entrypoint script by setting the `STARTUP_DELAY_IN_SECONDS` environment variable for the runner pod. This will cause the script to sleep X seconds, this works with any runner kind.
+
+```yaml
+apiVersion: actions.summerwind.dev/v1alpha1
+kind: RunnerDeployment
+metadata:
+  name: example-runnerdeployment-with-sleep
+spec:
+  template:
+    spec:
+      ...
+      env:
+        - name: STARTUP_DELAY_IN_SECONDS
+          value: "5"
+```
+
+## Outgoing network action hangs indefinitely
+
+**Problem**
+
+Some random outgoing network actions hangs indefinitely. This could be because your cluster does not give Docker the standard MTU of 1500, you can check this out by running `ip link` in a pod that encounters the problem and reading the outgoing interface's MTU value. If it is smaller than 1500, then try the following.
+
+**Solution**
+
+Add a `dockerMTU` key in your runner's spec with the value you read on the outgoing interface. For instance:
+
+```yaml
+apiVersion: actions.summerwind.dev/v1alpha1
+kind: RunnerDeployment
+metadata:
+  name: github-runner
+  namespace: github-system
+spec:
+  replicas: 6
+  template:
+    spec:
+      dockerMTU: 1400
+      repository: $username/$repo
+      env: []
+```
+
+There may be more places you need to tweak for MTU.
+Please consult issues like #651 for more information.
+
+## Unable to scale to zero with TotalNumberOfQueuedAndInProgressWorkflowRuns
+
+**Problem**
+
+HRA doesn't scale the RunnerDeployment to zero, even though you did configure HRA correctly, to have a pull-based scaling metric `TotalNumberOfQueuedAndInProgressWorkflowRuns`, and set `minReplicas: 0`.
+
+**Solution**
+
+You very likely have some dangling workflow jobs stuck in `queued` or `in_progress` as seen in [#1057](https://github.com/actions-runner-controller/actions-runner-controller/issues/1057#issuecomment-1133439061).
+
+Manually call [the "list workflow runs" API](https://docs.github.com/en/rest/actions/workflow-runs#list-workflow-runs-for-a-repository), and [remove the dangling workflow job(s)](https://docs.github.com/en/rest/actions/workflow-runs#delete-a-workflow-run).

+## Upgrading
+
+This project makes extensive use of CRDs to provide much of its functionality. Helm unfortunately does not support [managing](https://helm.sh/docs/chart_best_practices/custom_resource_definitions/) CRDs by design:
+
+_The full breakdown as to how they came to this decision and why they have taken the approach they have for dealing with CRDs can be found in [Helm Improvement Proposal 11](https://github.com/helm/community/blob/main/hips/hip-0011.md)_
+
+```
+There is no support at this time for upgrading or deleting CRDs using Helm. This was an explicit decision after much 
+community discussion due to the danger for unintentional data loss. Furthermore, there is currently no community 
+consensus around how to handle CRDs and their lifecycle. As this evolves, Helm will add support for those use cases.
+```
+
+Helm will do an initial install of CRDs but it will not touch them afterwards (update or delete).
+
+Additionally, because the project leverages CRDs so extensively you **MUST** run the matching controller app container with its matching CRDs i.e. always redeploy your CRDs if you are changing the app version.
+
+Due to the above you can't just do a `helm upgrade` to release the latest version of the chart, the best practice steps are recorded below:
+
+## Steps
+
+1. Upgrade CRDs, this isn't optional, the CRDs you are using must be those that correspond with the version of the controller you are installing
+
+```shell
+# REMEMBER TO UPDATE THE CHART_VERSION TO RELEVANT CHART VERISON!!!!
+CHART_VERSION=0.18.0
+
+curl -L https://github.com/actions-runner-controller/actions-runner-controller/releases/download/actions-runner-controller-${CHART_VERSION}/actions-runner-controller-${CHART_VERSION}.tgz | tar zxv --strip 1 actions-runner-controller/crds
+
+kubectl replace -f crds/
+```
+
+2. Upgrade the Helm release
+
+```shell
+# helm repo [command]
+helm repo update
+
+# helm upgrade [RELEASE] [CHART] [flags]
+helm upgrade actions-runner-controller \
+  actions-runner-controller/actions-runner-controller \
+  --install \
+  --namespace actions-runner-system \
+  --version ${CHART_VERSION}
+```
