## 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 v17.6.0-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
### Using Docker image (Zero setup)
Using this method license files are generated under `./license` directory
> Please note that in standard docker installations, owner of the files generated in license directory will be root
#### Method (1): Pull image
```bash
docker run --rm -it \
-v "./license:/license-generator/build" \
-e LICENSE_NAME="Tim Cook" \
-e LICENSE_COMPANY="Apple Computer, Inc." \
-e LICENSE_EMAIL="tcook@apple.com" \
-e LICENSE_PLAN="ultimate" \
-e LICENSE_USER_COUNT="2147483647" \
-e LICENSE_EXPIRE_YEAR="2500" \
ghcr.io/lakr233/gitlab-license-generator:main
```
#### Method (2): Build image
```bash
git clone https://github.com/Lakr233/GitLab-License-Generator.git
docker build GitLab-License-Generator -t gitlab-license-generator:main
docker run --rm -it \
-v "./license:/license-generator/build" \
-e LICENSE_NAME="Tim Cook" \
-e LICENSE_COMPANY="Apple Computer, Inc." \
-e LICENSE_EMAIL="tcook@apple.com" \
-e LICENSE_PLAN="ultimate" \
-e LICENSE_USER_COUNT="2147483647" \
-e LICENSE_EXPIRE_YEAR="2500" \
gitlab-license-generator:main
```
### Manual: 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)**:
```bash
sudo apt update
sudo apt install ruby-full
```
- **On macOS** (via Homebrew):
```bash
brew install ruby
```
#### 2. Install Bundler and necessary gems
After installing Ruby, you need to install **Bundler** to manage Ruby dependencies.
```bash
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.
```bash
gem install gitlab-license
```
### Steps to Generate the GitLab License
#### 1. Clone the project repository
Clone this project to your local machine.
```bash
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:
```bash
./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**:
```bash
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:
```yaml
volumes:
- "./build/public.key:/opt/gitlab/embedded/service/gitlab-rails/.license_encryption_key.pub"
```
Then restart the container:
```bash
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 bottom-left 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:
```
/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:
```bash
sudo nano /etc/gitlab/gitlab.rb
```
- Add the following line:
```bash
gitlab_rails['usage_ping_enabled'] = false
```
- Reconfigure and restart GitLab:
```bash
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).
