Introduced in GitLab 8.12.

Checks if your .gitlab-ci.yml file is valid.

POST /ci/lint

Attribute	Type	Required	Description
content	string	yes	the .gitlab-ci.yaml content

curl --header "Content-Type: application/json" "https://gitlab.example.com/api/v4/ci/lint" --data '{"content": "{ \"image\": \"ruby:2.6\", \"services\": [\"postgres\"], \"before_script\": [\"bundle install\", \"bundle exec rake db:create\"], \"variables\": {\"DB_NAME\": \"postgres\"}, \"types\": [\"test\", \"deploy\", \"notify\"], \"rspec\": { \"script\": \"rake spec\", \"tags\": [\"ruby\", \"postgres\"], \"only\": [\"branches\"]}}"}'

Be sure to copy paste the exact contents of .gitlab-ci.yml as YAML is very picky about indentation and spaces.

Example responses:

• Valid content:

  {
    "status": "valid",
    "errors": []
  }
  

• Invalid content:

  {
    "status": "invalid",
    "errors": [
      "variables config should be a hash of key value pairs"
    ]
  }
  

• Without the content attribute:

  {
    "error": "content is missing"
  }
