GitLab CI

What It Is

CI/CD inside GitLab through .gitlab-ci.yml, runners, and environments.

Core Ideas

• stages and jobs
• shared and dedicated runners
• variables and secrets
• artifacts and cache

Minimal Example

stages:
  - test

test:
  stage: test
  script:
    - echo "run tests"

Practice

• Keep cache and artifacts conceptually separate.
• For deploy jobs, use explicit branch and environment restrictions.
