Description

GitLab License Generator This project generates a GitLab license for development purposes. If you encounter any problems, please troubleshoot them on your own.

Last tested on GitLab v17.4.2-ee.

Principles

src/generator.keys.rb

GitLab uses a public/private key pair to encrypt its license. The public key is shipped with the GitLab distribution, while the private key is kept secure. The license itself is simply a JSON dictionary. Since GitLab has made its code open-source, we can easily generate our own license.

src/generator.license.rb

The lib folder is extracted from GitLab's source code. It is used to build and validate the license. The script src/generator.license.rb loads this functionality.

src/scan.features.rb

Features are extracted from an object filled with constants. The most comprehensive plan for a license is Ultimate, but features like Geo Mirroring are not included in any standard plan. Therefore, we manually add these features.

Usage

Prerequisites

Before starting, ensure your environment is properly configured.

1. Install Ruby and gem

To run this project, you need Ruby and the gem package manager.

• On Linux (Ubuntu/Debian):

  sudo apt update
  sudo apt install ruby-full

• On macOS (via Homebrew):

  brew install ruby

2. Install Bundler and necessary gems

After installing Ruby, you need to install Bundler to manage Ruby dependencies.

gem install bundler

3. Install the gitlab-license gem

The project requires the gitlab-license gem, which will be automatically downloaded and used by the script.

gem install gitlab-license

Steps to Generate the GitLab License

1. Clone the project repository

Clone this project to your local machine.

git clone https://github.com/Lakr233/GitLab-License-Generator.git
cd GitLab-License-Generator

2. Run the make.sh script

Once all the prerequisites are met, run the script:

./make.sh

The script will perform the following actions:

• Download and extract the gitlab-license gem.
• Copy and modify the required files.
• Clone the GitLab source code from GitLab.com.
• Generate a public/private key pair.
• Generate a GitLab license.

3. Replace the public key in GitLab

The script generates a public key located in build/public.key. You need to replace GitLab’s existing public key with this newly generated one to ensure the license is accepted.

• If GitLab is installed on your server:

  sudo cp ./build/public.key /opt/gitlab/embedded/service/gitlab-rails/.license_encryption_key.pub
  sudo gitlab-ctl reconfigure
  sudo gitlab-ctl restart

• If GitLab is installed via Docker: Modify your docker-compose.yml file to mount the new public key inside the container:

  volumes:
    - "./build/public.key:/opt/gitlab/embedded/service/gitlab-rails/.license_encryption_key.pub"

  Then restart the container:

  docker-compose down
  docker-compose up -d

4. Install the license in GitLab

Once the public key is replaced, log in to GitLab’s admin interface to install the generated license.

1. Log in to GitLab as an administrator.
2. Navigate to the Admin Area from the upper-right corner.
3. Go to Settings > General and upload the generated license file (build/result.gitlab-license).
4. Check the Terms of Service checkbox and click Add License.

If necessary, you can directly access the license upload page via:

<YourGitLabURL>/admin/license/new

5. Disable Service Ping (optional)

If you want to disable GitLab’s usage data collection (Service Ping), modify GitLab’s configuration file:

• Open the configuration file:

  sudo nano /etc/gitlab/gitlab.rb

• Add the following line:

  gitlab_rails['usage_ping_enabled'] = false

• Reconfigure and restart GitLab:

  sudo gitlab-ctl reconfigure
  sudo gitlab-ctl restart

Troubleshooting

• HTTP 502 Error: If you encounter this error, wait for GitLab to finish starting up (it may take some time).
