Original GitHub issue: https://github.com/nektos/act/issues/47

I noticed that github actions are run using the following container: gcr.io/github-actions-images/action-runner

https://console.cloud.google.com/gcr/images/github-actions-images/GLOBAL/action-runner?gcrImageListsize=30

$ docker run gcr.io/github-actions-images/action-runner:latest --help
Usage of action-runner:
  -action-id string
    	Unique identifier for action execution
  -debug
    	Indicates whether to output Debug logs
  -entrypoint string
    	Overwrite the default ENTRYPOINT of the image
  -env-keys string
    	Specifies which environment variables to copy to container (defaults to all)
  -forward-mount value
    	Mount paths to forward
  -image string
    	Which image to run
  -reporting-url string
    	URL to report progress
  -secret-keys string
    	Environment variable keys to filter from output (comma-separated
  -signing-key string
    	Path to signing key
  -working-dir string
    	Working directory for container

Here's an example run on github:

It might be useful to keep in sync local functionality by matching what the real github actions uses.

@dougnukem Do you know where the Dockerfile is for this image? How did you work out you could append --help on the end for example. Thanks
