Common Workflows

Workflow 1: Set Up Standard Badges

project_id=123

# Pipeline status
glab api projects/$project_id/badges --method POST \
  -f name="Pipeline" \
  -f link_url="https://gitlab.com/%{project_path}/-/pipelines" \
  -f image_url="https://gitlab.com/%{project_path}/badges/%{default_branch}/pipeline.svg"

# Coverage
glab api projects/$project_id/badges --method POST \
  -f name="Coverage" \
  -f link_url="https://gitlab.com/%{project_path}/-/jobs" \
  -f image_url="https://gitlab.com/%{project_path}/badges/%{default_branch}/coverage.svg"

# Latest release
glab api projects/$project_id/badges --method POST \
  -f name="Release" \
  -f link_url="https://gitlab.com/%{project_path}/-/releases" \
  -f image_url="https://gitlab.com/%{project_path}/-/badges/release.svg"

Workflow 2: Generate README Badge Markdown

# Get all badges and generate markdown
glab api projects/123/badges | \
  jq -r '.[] | "[![\(.name // "badge")](\(.rendered_image_url))](\(.rendered_link_url))"'

Workflow 3: Copy Badges to Another Project

source_project=123
target_project=456

# Get badges from source
badges=$(glab api projects/$source_project/badges)

# Create in target (using placeholders, so they'll work for the new project)
echo "$badges" | jq -c '.[]' | while read badge; do
  link_url=$(echo "$badge" | jq -r '.link_url')
  image_url=$(echo "$badge" | jq -r '.image_url')
  name=$(echo "$badge" | jq -r '.name // empty')

  glab api projects/$target_project/badges --method POST \
    -f link_url="$link_url" \
    -f image_url="$image_url" \
    ${name:+-f name="$name"}
done

Workflow 4: Audit Badge Configuration

# List all badges with rendered URLs
glab api projects/123/badges | \
  jq -r '.[] | "ID: \(.id)\n  Name: \(.name // "unnamed")\n  Image: \(.rendered_image_url)\n  Link: \(.rendered_link_url)\n"'

Workflow 5: Replace All Badges

project_id=123

# Delete existing badges
glab api projects/$project_id/badges | jq -r '.[].id' | while read badge_id; do
  glab api projects/$project_id/badges/$badge_id --method DELETE
done

# Create new badges
glab api projects/$project_id/badges --method POST \
  -f name="Build" \
  -f link_url="https://gitlab.com/%{project_path}/-/pipelines" \
  -f image_url="https://gitlab.com/%{project_path}/badges/%{default_branch}/pipeline.svg"

Troubleshooting

Issue	Cause	Solution
Badge not showing	URL incorrect	Check rendered URLs in API response
403 Forbidden	Not maintainer	Need Maintainer+ role
Placeholder not replaced	Wrong syntax	Use %{placeholder} format
Coverage badge shows "unknown"	No coverage report	Configure CI to output coverage
Pipeline badge shows old status	Cache	Badge images may be cached

Badge Best Practices

1. Use placeholders: Make badges portable between projects
2. Name your badges: Helps identify them in the list
3. Link to relevant pages: Badge clicks should go somewhere useful
4. Keep badges updated: Remove stale badges
5. Use consistent styling: Mix of GitLab and shields.io can look inconsistent
