Deploiement avec GitLab CI/CD

Environments GitLab

Les environments representent les cibles de deploiement (staging, production, etc.).

stages:
  - build
  - test
  - deploy

deploy-staging:
  stage: deploy
  script:
    - echo "Deploiement sur staging..."
    - rsync -avz dist/ deploy@staging-server:/var/www/app/
  environment:
    name: staging
    url: https://staging.mon-app.com
  rules:
    - if: $CI_COMMIT_BRANCH == "develop"

deploy-production:
  stage: deploy
  script:
    - echo "Deploiement en production..."
    - rsync -avz dist/ deploy@prod-server:/var/www/app/
  environment:
    name: production
    url: https://mon-app.com
  rules:
    - if: $CI_COMMIT_BRANCH == "main"
  when: manual

Deploiement manuel (approval)

Le mot-cle when: manual oblige un utilisateur a cliquer pour lancer le deploiement.

deploy-production:
  stage: deploy
  script:
    - ./deploy.sh production
  environment:
    name: production
  when: manual
  allow_failure: false  # Le pipeline attend l'approbation

Deploiement avec Docker

deploy-docker:
  stage: deploy
  image: docker:latest
  services:
    - docker:dind
  script:
    - docker login -u $CI_REGISTRY_USER -p $CI_REGISTRY_PASSWORD $CI_REGISTRY
    - docker build -t $CI_REGISTRY_IMAGE:$CI_COMMIT_SHA .
    - docker push $CI_REGISTRY_IMAGE:$CI_COMMIT_SHA
    - ssh deploy@server "docker pull $CI_REGISTRY_IMAGE:$CI_COMMIT_SHA && docker-compose up -d"
