This documentation outlines the CI/CD deployment process associated with the gitlab-org/gitlab-ce project, detailing how CI/CD is set up, configured, and executed. This guide is tailored for expert developers familiar with the GitLab ecosystem, aiming to provide a comprehensive view of the deployment workflows.
CI/CD Deployment Overview
If CI/CD is not yet set up in the project, it is essential to establish it to automate builds, tests, and deployment processes.
Step 1: Confirm CI/CD Configuration
To start, check the presence of a .gitlab-ci.yml file, which defines the CI/CD pipeline for the project.
If the file exists, examine its contents for stages, jobs, and deployment configurations. If it does not exist, follow the next steps to create one.
Step 2: Create a .gitlab-ci.yml File
If CI/CD is not yet configured, you will need to create a .gitlab-ci.yml file in the root of the repository.
Here is a basic structure for the .gitlab-ci.yml file:
image: gitlab/gitlab-ce:latest
stages:
- build
- test
- deploy
build:
stage: build
script:
- echo "Building the application..."
- # Add your build commands here
test:
stage: test
script:
- echo "Running tests..."
- # Add your test commands here
deploy:
stage: deploy
script:
- echo "Deploying the application..."
- # Add your deployment commands here
when: manual # Optional: Set to manual for controlled deployment
Step 3: Configure the Pipeline
Once the .gitlab-ci.yml is created, you can customize the build, test, and deploy scripts according to your requirements. Each job is defined under its corresponding stage.
- Build Stage: Compile or package the application.
- Test Stage: Run unit tests or integration tests.
- Deploy Stage: Deploy the application to the desired environment.
Step 4: Utilize Docker in CI/CD
The project utilizes Docker in its deployment process. The docker-compose.yml file indicates the image to use when running the CI/CD pipeline:
app:
image: gitlab/gitlab-ce:latest
Incorporating Docker can help streamline the build process and ensure consistency across environments.
Example Job Using Docker
Below is an example of how to use Docker in a CI/CD job:
build:
stage: build
image: gitlab/gitlab-ce:latest
script:
- echo "Building the Docker image..."
- docker build -t my-app:latest .
Step 5: Running the Pipeline
After setting up the .gitlab-ci.yml file, commit the changes to the repository. GitLab will automatically trigger the CI/CD pipeline based on the defined configuration.
Use the GitLab UI to monitor the status of your pipeline and to troubleshoot any issues that may arise during the build, test, or deployment stages.
Next Steps if CI/CD is Not Configured
If the CI/CD process is not yet established, consider the following next steps:
Create a .gitlab-ci.yml file – Follow the structure outlined above.
Define CI/CD stages and jobs – Customize the stages and corresponding jobs based on your project needs.
Test the CI/CD pipeline – After committing the setup, ensure it runs successfully by checking the pipeline results.
By following these steps, you will lay a strong foundation for CI/CD within the gitlab-org/gitlab-ce project, enhancing automation, efficiency, and code quality.
This documentation is derived from project configuration files within the gitlab-org/gitlab-ce repository, specifically focusing on deployment aspects relevant to CI/CD processes.
