GitLab migrations powered by GitHub Actions Importer

These instructions will guide you through configuring the GitHub Codespaces environment that you will use in these labs to learn how to use GitHub Actions Importer to migrate GitLab pipelines to GitHub Actions.

These steps must be completed prior to starting other labs.

Create your own repository for these labs

Configure your codespace

  1. Start a new codespace

    • Click the Code button on your repository's landing page.
    • Click the Codespaces tab.
    • Click Create codespaces on main to create the codespace.
    • After the codespace has initialized there will be a terminal present.

  2. Verify the GitHub Actions Importer CLI is installed and working. More information on the GitHub Actions Importer extension for the official GitHub CLI can be found here.

    • Run the following command in the codespace terminal:

      gh actions-importer version

    • Verify the output is similar to below.

      $ gh actions-importer version
gh version 2.14.3 (2022-07-26)
gh actions-importer        github/gh-actions-importer v0.1.12
actions-importer/cli       unknown

    • If gh actions-importer version did not produce similar output, please refer to the troubleshooting section.

Bootstrap a GitLab server

  1. Execute the GitLab setup script that will start a container with GitLab running inside of it. The script should be executed when starting a new codespace or restarting an existing one.

    • Run the following command from the codespace terminal:

      ./gitlab/bootstrap/setup.sh

    • After some time, a pop-up box should appear with a link to the URL for your GitLab server.

    • You can also access the URL by going to the Ports tab in your terminal. Right-click the URL listed under the Local Address and click the Open in Browser tab.

  2. Open the GitLab server in your browser and use the following credentials to authenticate:

    • Username: root
    • Password: actions-importer-labs!

  3. Once authenticated, you should see a GitLab server with a few predefined pipelines in the actions-importer group.

Labs for GitLab

Perform the following labs to learn more about Actions migrations with GitHub Actions Importer:

  1. Configure credentials for GitHub Actions Importer
  2. Perform an audit on GitLab pipelines
  3. Forecast potential build runner usage
  4. Perform a dry-run migration of a GitLab pipeline
  5. Use custom transformers to customize GitHub Actions Importer's behavior
  6. Perform a production migration of a GitLab pipeline

Troubleshoot the GitHub Actions Importer CLI

The CLI extension for GitHub Actions Importer can be manually installed by following these steps:

  • Verify you are in the codespace terminal

  • Run this command from within the codespace terminal:

    gh extension install github/gh-actions-importer

  • Verify the result of the install contains:

    $ gh extension install github/gh-actions-importer
✓ Installed extension github/gh-actions-importer

  • Verify GitHub Actions Importer CLI extension is installed and working by running the following command from the codespace terminal:

    gh actions-importer version
