To create your own github actions worker, follow these instructions:
mkdir actions-runner && cd actions-runner
curl -o actions-runner-linux-x64-2.319.0.tar.gz -L https://github.com/actions/runner/releases/download/v2.319.0/actions-runner-linux-x64-2.319.0.tar.gz
tar xzf ./actions-runner-linux-x64-2.319.0.tar.gz
./config.sh --url https://github.com/your-repo-owner/your-repo-name --token YOUR_PERSONAL_ACCESS_TOKEN
./run.sh
Then, your runner will pick up jobs it can.
