Gitlab Ci Patterns

Solid collection of GitLab CI patterns that covers the essentials without getting lost in edge cases. The Docker build examples handle registry authentication properly, the multi-environment deployment uses YAML anchors to avoid repetition, and the caching configurations actually make sense for real projects. The Terraform pipeline includes the validation and manual approval gates you'd want in production. Security scanning integration uses both GitLab's built-in templates and Trivy for container scanning. The dynamic child pipeline example is genuinely useful for monorepos where you need different pipelines based on what changed.

GitLab CI Patterns

Comprehensive GitLab CI/CD pipeline patterns for automated testing, building, and deployment.

Purpose

Create efficient GitLab CI pipelines with proper stage organization, caching, and deployment strategies.

When to Use

Automate GitLab-based CI/CD
Implement multi-stage pipelines
Configure GitLab Runners
Deploy to Kubernetes from GitLab
Implement GitOps workflows

Basic Pipeline Structure

stages:
  - build
  - test
  - deploy

variables:
  DOCKER_DRIVER: overlay2
  DOCKER_TLS_CERTDIR: "/certs"

build:
  stage: build
  image: node:20
  script:
    - npm ci
    - npm run build
  artifacts:
    paths:
      - dist/
    expire_in: 1 hour
  cache:
    key: ${CI_COMMIT_REF_SLUG}
    paths:
      - node_modules/

test:
  stage: test
  image: node:20
  script:
    - npm ci
    - npm run lint
    - npm test
  coverage: '/Lines\s*:\s*(\d+\.\d+)%/'
  artifacts:
    reports:
      coverage_report:
        coverage_format: cobertura
        path: coverage/cobertura-coverage.xml
