Configuring the CI/CD pipeline in GitLab requires knowledge of the YAML syntax and the specifics of gitlab-ci.yml: stages, jobs, rules, cache, artifacts, variables and connection to GitLab Container Registry or Kubernetes. The tool generates a complete file based on the selected technology stack.
.gitlab-ci.yml structure
Stages: order of stages (build → test → deploy). Jobs: jobs in stages (can be parallel). Script: commands to execute. Image: Docker image for job. Cache: directories between jobs (e.g. node_modules). Artifacts: files passed between stages (e.g. dist/). Rules/only/except: conditional launch.
Ready-made stack templates
Node.js: npm ci + test + build + Dockerfile + push to registry. Python: pip install + pytest + coverage report. PHP: composer install + phpunit + phpstan. Docker: multi-stage build + trivy security scan + push. Java/Maven: mvn test + jar + deploy. Go: go test + go build + binary artifact.
Pipeline optimization
Cache node_modules (key: ${CI_COMMIT_REF_SLUG}): significantly speeds up builds. Parallel jobs: matrix strategy for multiple versions of Node/Python. Interruptible: true: new push cancels old job of the same branch. Needs (DAG): job starts when the predecessor is ready, without waiting for the entire stage. Dind (Docker-in-Docker): building images in CI.
Deploy and environments
GitLab Environments: automatic creation of environments (review apps for MR). Kubernetes: helm upgrade or kubectl apply from kubeconfig from CI variables. SSH deploy: rsync + SSH key in CI/CD variables. GitLab Pages: artifacts:paths: [public/] + pages job – automatic deployment of a static page.
FAQ
How is GitLab CI different from GitHub Actions?
GitLab CI: native, .gitlab-ci.yml, built-in Container Registry, self-hosted available. GitHub Actions: .github/workflows/*.yml, action marketplace, free for public repositories. The syntax is different but the concepts (stages/jobs/matrix) are similar. GitLab has built-in security scanning (DAST/SAST).
How to speed up a slow CI pipeline?
Cache dependencies (node_modules, pip cache, composer). Parallel test splits (pytest-split, is --shard). Interruptible: true for the feature branch. Docker layer caching (--cache-from). Incremental builds. Skip unnecessary stages (rules: changes: [src/**/*]).
How to store secrets securely in GitLab CI?
GitLab CI/CD Variables (Settings → CI/CD → Variables): Masked (does not appear in logs) + Protected (only for protected branches). Vault integration: HashiCorp Vault as external secrets backend. Never commit secrets to .gitlab-ci.yml – only references: $SECRET_NAME.
What is GitLab Runner and how to run it?
GitLab Runner is an agent that performs jobs. Executor types: Shell (host OS), Docker (isolation), Kubernetes (cloud-native). Installation: curl -L https://packages.gitlab.com/install/repositories/runner/gitlab-runner/script.deb.sh | sudo bash && sudo apt install gitlab-runner. Registration: gitlab-runner register.
How to use GitLab Container Registry?
In .gitlab-ci.yml: image: docker:dind. Login: echo $CI_REGISTRY_PASSWORD | docker login -u $CI_REGISTRY_USER $CI_REGISTRY --password-stdin. Build: docker build -t $CI_REGISTRY_IMAGE:$CI_COMMIT_SHA. Push: docker push $CI_REGISTRY_IMAGE:$CI_COMMIT_SHA.
