GitLab

# 1. Merge request - GitLab's PR equivalent
git checkout -b feat/login-form
# ... edit, commit, push ...
# Push prints a URL to open the MR; or use:
glab mr create --fill --target-branch=main


# 2. Protected branches
# Settings -> Repository -> Protected branches
# - main: only Maintainers can push
# - Disallow force push
# - Require approvals (CODEOWNERS supported)
# - Require at least N approvals from CODEOWNERS


# 3. CODEOWNERS
# Path-based ownership (similar to GitHub)
[Backend]
/src/api/        @backend-team
/src/db/         @data-team @backend-team

# 5. Environments + auto-deploys
# Define environments in CI to get review apps and stop-deploy controls.
# Review apps spin up per MR for preview.


# 6. Container registry, packages, dependency proxy - built in
# docker login $CI_REGISTRY -u $CI_REGISTRY_USER -p $CI_JOB_TOKEN
# docker build -t $CI_REGISTRY_IMAGE:$CI_COMMIT_SHORT_SHA .
# docker push $CI_REGISTRY_IMAGE:$CI_COMMIT_SHORT_SHA


# 7. glab - the unofficial GitHub CLI equivalent
# glab auth login
# glab mr list, glab mr view, glab pipeline status

# Useful CLI bits
glab mr checkout 42       # check out an MR locally
glab issue create
glab ci status

# GitLab: built-in CI, Container Registry, Issue Boards.
glab repo create my-app
