 Docker Github Actions Runner
 ============================
 
-[![Docker Pulls](https://img.shields.io/docker/pulls/myoung34/github-runner.svg)](https://hub.docker.com/r/myoung34/github-runner)
+[![Docker Pulls](https://img.shields.io/docker/pulls/myoung34/github-runner.svg)](https://hub.docker.com/r/myoung34/github-runner) [![awesome-runners](https://img.shields.io/badge/listed%20on-awesome--runners-blue.svg)](https://github.com/jonico/awesome-runners)
 
 This will run the [new self-hosted github actions runners](https://help.github.com/en/actions/automating-your-workflow-with-github-actions/hosting-your-own-runners).
 
+## Notes ##
+
+### Docker Support ###
+
+Please note that while this runner installs and allows docker, github actions itself does not support using docker from a self hosted runner yet.
+For more information:
+
+* https://github.com/actions/runner/issues/406
+* https://github.com/actions/runner/issues/367
+
+Also, some GitHub Actions Workflow features, like [Job Services](https://docs.github.com/en/actions/guides/about-service-containers), won't be usable and [will result in an error](https://github.com/myoung34/docker-github-actions-runner/issues/61).
+
+### Docker-Compose on ARM ###
+
+Please note `docker-compose` does not currently work on ARM ([see issue](https://github.com/docker/compose/issues/6831)) so it is not installed on ARM based builds here.
+A workaround exists, please see [here](https://github.com/myoung34/docker-github-actions-runner/issues/72#issuecomment-804723656)

 | `RUNNER_NAME` | The name of the runner to use. Supercedes (overrides) `RUNNER_NAME_PREFIX` |
 | `RUNNER_NAME_PREFIX` | A prefix for a randomly generated name (followed by a random 13 digit string). You must not also provide `RUNNER_NAME`. Defaults to `github-runner` |
 | `ACCESS_TOKEN` | A [github PAT](https://docs.github.com/en/github/authenticating-to-github/creating-a-personal-access-token) to use to generate `RUNNER_TOKEN` dynamically at container start. Not using this requires a valid `RUNNER_TOKEN` |
-| `ORG_RUNNER` | Only valid if using `ACCESS_TOKEN`. This will set the runner to an org runner. Default is 'false'. Valid values are 'true' or 'false'. If this is set to true you must also set `ORG_NAME` and makes `REPO_URL` unneccesary |
-| `ORG_NAME` | The organization name for the runner to register under. Requires `ORG_RUNNER` to be 'true'. No default value. |
+| `RUNNER_SCOPE` | The scope the runner will be registered on. Valid values are `repo`, `org` and `ent`. For 'org' and 'enterprise', `ACCESS_TOKEN` is required and `REPO_URL` is unneccesary. If 'org', requires `ORG_NAME`; if 'enterprise', requires `ENTERPRISE_NAME`. Default is 'repo'. |

 | `REPO_URL` | If using a non-organization runner this is the full repository url to register under such as 'https://github.com/myoung34/repo' |
 | `RUNNER_TOKEN` | If not using a PAT for `ACCESS_TOKEN` this will be the runner token provided by the Add Runner UI (a manual process). Note: This token is short lived and will change frequently. `ACCESS_TOKEN` is likely preferred. |
 | `RUNNER_WORKDIR` | The working directory for the runner. Runners on the same host should not share this directory. Default is '/_work'. This must match the source path for the bind-mounted volume at RUNNER_WORKDIR, in order for container actions to access files. |
+| `RUNNER_GROUP` | Name of the runner group to add this runner to (defaults to the default runner group) |
+| `GITHUB_HOST` | Optional URL of the Github Enterprise server e.g github.mycompany.com. Defaults to `github.com`. |
+| `DISABLE_AUTOMATIC_DEREGISTRATION` | Optional flag to disable signal catching for deregistration. Default is `false`. Any value other than exactly `false` is considered `true`. See [here](https://github.com/myoung34/docker-github-actions-runner/issues/94) |
+| `CONFIGURED_ACTIONS_RUNNER_FILES_DIR` | Path to use for runner data. It allows avoiding reregistration each the start of the runner. No default value. |

+## Ephemeral mode
+
+GitHub's hosted runners are completely ephemeral.  You can remove all its data without breaking all future jobs.
+
+To achieve the same resilience in a self-hosted runner:
+  1. override the command for your runner with `/ephemeral-runner.sh` (which will terminate after one job executes)
+  2. don't mount a local folder into `RUNNER_WORKDIR` (to ensure no filesystem persistence)
+  3. run the container with `--rm` (to delete it after termination)
+  4. wrap the container execution in a system service that restarts (to start a fresh container after each job)
+
+Here's an example service definition for systemd:
+
+```
+# Install with:
+#   sudo install -m 644 ephemeral-github-actions-runner.service /etc/systemd/system/
+#   sudo systemctl daemon-reload
+#   sudo systemctl enable ephemeral-github-actions-runner
