Breaks up the ARC documentation into several smaller articles. `@vijay-train` and `@martin389` put together the plan for this update, and I've just followed it here. In these updates: - The README has been updated to include more general project information, and link to each new article. - The `detailed-docs.md` file has been broken up into multiple articles, and then deleted. - The Actions Runner Controller Overview doc has been renamed to `about-arc.md`. Any edits to content beyond generally renaming headers or fixing typos is out of scope for this PR, but will be made in the future.

## Runner Entrypoint Features
|
|

|
> Environment variable values must all be strings
|
|
|

The entrypoint script is aware of a few environment variables for configuring features:
|
|
|
|
```yaml
|
|
apiVersion: actions.summerwind.dev/v1alpha1
|
|
kind: RunnerDeployment
|
|
metadata:
|
|
name: example-runnerdeployment
|
|
spec:
|
|
template:

|
spec:
|
|
env:
|
|
# Disable various runner entrypoint log levels
|
|
- name: LOG_DEBUG_DISABLED
|
|
value: "true"
|
|
- name: LOG_NOTICE_DISABLED

|
|
# Issues a sleep command at the start of the entrypoint
|
|
- name: STARTUP_DELAY_IN_SECONDS
|
|
value: "2"
|
|
# Specify the duration to wait for the docker daemon to be available
|
|
# The default duration of 120 seconds is sometimes too short
|
|
# to reliably wait for the docker daemon to start
|
|
# See https://github.com/actions/actions-runner-controller/issues/1804
|
|
- name: WAIT_FOR_DOCKER_SECONDS
|
|
value: 120
|
|
# Disables the wait for the docker daemon to be available check
|
|
- name: DISABLE_WAIT_FOR_DOCKER
|
|
value: "true"
|
|
# Disables automatic runner updates
|
|

```

There are a few advanced envvars also that are available only for dind runners:
|
|
|
|
```yaml
|
|
apiVersion: actions.summerwind.dev/v1alpha1
|
|
kind: RunnerDeployment
|
|
metadata:
|
|
name: example-runnerdeployment
|
|
spec:
|
|
template:
|
|
spec:
|
|
dockerdWithinRunnerContainer: true
|
|
image: summerwind/actions-runner-dind
|
|
env:
|
|
# Sets the respective default-address-pools fields within dockerd daemon.json
|
|
# See https://github.com/actions/actions-runner-controller/pull/1971 for more information.
|
|
# Also see https://github.com/docker/docs/issues/8663 for the default base/size values in dockerd.
|
|
- name: DOCKER_DEFAULT_ADDRESS_POOL_BASE
|
|
value: "172.17.0.0/12"
|
|
- name: DOCKER_DEFAULT_ADDRESS_POOL_SIZE
|
|
