Since a github runner is associated to an organization, the following are required to create a self-hosted runner

1. Github organization
2. Runner token

Navigate to your Organiztion settings –> Actions –> Runners –> New runner –> New self-hosted runner

Select Linux and the ARM64 architecture. This will provide you with the token.

Alternatively, this can be performed via the Github API

Set the following as envirnoment variables or store them directly in build.sh

ORGANIZATION TOKEN

./build.sh will build the runner image with name runner

docker run -it --rm runner

The entrypoint.sh script will automatically de-register the runner when the container is stopped. Feel free to adjust this behaviour if it undesired.
