GitHub Actions stands as a versatile tool, simplifying the automation of all your software workflows. This integrated CI/CD solution handles an extensive array of tasks tied to your repository.

GitHub offers a limited range of complementary resources for constructing applications through GitHub Actions; however, proficient developers can swiftly encounter these constraints. Teams engaged in professional-grade projects might also want full authority over their build environment. GitHub extends the option to use runners on self-managed instances. A runner functions is an application executing tasks from a GitHub Actions workflow.

In this guide, you will learn how to configure a GitHub Actions runner on a Scaleway Instance, effectively streamlining your project workflows. For typical workloads, opting for a Cost-Optimized Instance is recommended. For resource-intensive workloads, the use of Production-Optimized Instances provides dedicated resources for enhanced performance.

Tip:

We recommend you follow this tutorial using a Cost-Optimized Instance.

Security & Identity (IAM):

You may need certain IAM permissions to carry out some actions described on this page. This means:

  • you are the Owner of the Scaleway Organization in which the actions will be carried out, or
  • you are an IAM user of the Organization, with a policy granting you the necessary permission sets
Requirements:

Adding a workflow to your repository

  1. Log into your GitHub account and select the repository in which you want to add GitHub Actions.
  2. Click the Actions tab in your repository. A list of available workflows for your project displays.
  3. Select the workflow that corresponds to your project and click Set up this workflow. You can either create a workflow from scratch or use one of the templates suggested.
  4. Edit the workflow according to your requirements. For more information about GitHub Actions, refer to the product documentation. Once configured, save the workflow.

Installing a GitHub runner

  1. Connect to your Instance via SSH.
  2. Create a user for the GitHub runner.
    adduser ghrunner
  3. Add the user to the superuser file:
    adduser ghrunner sudo
  4. Switch into the ghrunner user account
    su ghrunner
  5. Download and unpack the GitHub runner using the following commands:
    # Create a folder
    mkdir actions-runner && cd actions-runner
    # Download the latest runner package
    curl -O -L https://github.com/actions/runner/releases/download/v2.309.0/actions-runner-linux-x64-2.309.0.tar.gz
    # Extract the installer
    tar xzf ./actions-runner-linux-x64-2.309.0.tar.gz
    Tip:

    You may check the GitHub runner repository for the latest release of the runner.

Adding the runner to your GitHub repository

  1. Go back to your GitHub repository and click the Settings tab. Then click Actions in the side menu.

  2. Click Runners in the Actions section of the side menu. The external runners overview page displays.

  3. Click Add runner.

  4. The runners configuration instruction displays. Select the OS type of your OS (Linux, X64) and scroll down to Configure section of the page.

  5. Copy the configuration information displayed and execute the config.sh on your Instance:

    ./config.sh --url https://github.com/scaleway-community/my-project --token AC6XRSJUUEWXLYJ7SQ6WMVLASKYWZ
    Note:

    If you run the config.sh script without flags, you must provide the repository URL and token during the configuration.

    The configuration tool connects to GitHub using the given token.

  6. Enter the name of the runner during the runner configuration. It gets automatically several tags attached to it. Optionally you can enter custom tags. When prompted, enter the work directory of the runner. You can confirm the default values by pressing enter. Otherwise enter your customized values before pressing enter.

  7. The runner is configured. Once everything is ready, the following message displays:

    √ Runner successfully added
    √ Runner connection is good
    [...]
    √ Settings Saved.
  8. Launch the runner using the following command:

    ./run.sh

Your self-hosted GitHub runner is now ready and you can check its status from the Runners section of your GitHub repository:

To run your CI/CD tasks on your self-hosted runner, add this YAML in your workflow file for each job:

runs-on: self-hosted
