github actions register multiple runners on a machine

 

To allow a single Docker host runner to handle multiple jobs simultaneously, you need to modify the runner configuration to register multiple runner processes on the same host machine. :

Steps to Register Multiple Runner Processes:

1. Create a New Runner Directory: Each runner instance requires its own directory. To register multiple runners, create separate directories for each one.
   

   mkdir actions-runner-2
   cd actions-runner-2
   

2. Download and Configure Another Runner: You can download the runner from your GitHub repository or organization.
   

   # Download the latest runner package
   curl -o actions-runner-linux-x64-2.308.0.tar.gz -L https://github.com/actions/runner/releases/download/v2.308.0/actions-runner-linux-x64-2.308.0.tar.gz
   
   # Extract the installer
   tar xzf ./actions-runner-linux-x64-2.308.0.tar.gz
   

3. Register the Runner: Register the second runner using a different name for the same repository or organization.
   

   ./config.sh --url https://github.com/<owner>/<repo> --token <registration_token>
   

   
   You can get the <registration_token> from your GitHub repository or organization settings under Settings > Actions > Runners.

4. Start the New Runner: Start the new runner so it can handle additional jobs.
   
   

   ./svc.sh install
   ./svc.sh start
   

   
   
   Now, you should have two runners registered on the same machine, which can handle two jobs simultaneously.

5. Repeat for More Runners: If you want to handle more concurrent jobs, repeat the above steps, creating more runner directories (e.g., actions-runner-3, etc.) and registering them.

6. Runners can be created as a background service using these steps.
