CI Lint API

Validate the CI YAML configuration

Introduced in GitLab 8.12.

Checks if CI/CD YAML configuration is valid. This endpoint validates basic CI/CD configuration syntax. It doesn't have any namespace specific context.

Access to this endpoint does not require authentication when the instance allows new sign ups and:

Does not have an allowlist or denylist.
Does not require administrator approval for new sign ups.
Does not have additional sign up restrictions.

Otherwise, authentication is required.

POST /ci/lint

Attribute	Type	Required	Description
`content`	string	yes	The CI/CD configuration content.
`include_merged_yaml`	boolean	no	If the expanded CI/CD configuration should be included in the response.

curl --header "Content-Type: application/json" --header "PRIVATE-TOKEN: <your_access_token>" "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 paste the exact contents of your GitLab CI/CD YAML configuration because YAML is very sensitive about indentation and spacing.

Example responses:

Valid content:

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

Valid content with warnings:

{
  "status": "valid",
  "errors": [],
  "warnings": ["jobs:job may allow multiple pipelines to run for a single action due to
  `rules:when` clause with no `workflow:rules` - read more:
  https://docs.gitlab.com/ee/ci/troubleshooting.html#pipeline-warnings"]
}

Invalid content:

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

Without the content attribute:
```
{
  "error": "content is missing"
}
```

YAML expansion

Introduced in GitLab 13.5.

The CI lint returns an expanded version of the configuration. The expansion does not work for CI configuration added with include: local, or with extends:.

Example contents of a .gitlab-ci.yml passed to the CI Lint API with include_merged_yaml set as true:

include:
  remote: 'https://example.com/remote.yaml'

test:
  stage: test
  script:
    - echo 1

Example contents of https://example.com/remote.yaml:

another_test:
  stage: test
  script:
    - echo 2

Example response:

{
  "status": "valid",
  "errors": [],
  "merged_config": "---\n:another_test:\n  :stage: test\n  :script: echo 2\n:test:\n  :stage: test\n  :script: echo 1\n"
}

Validate a CI YAML configuration with a namespace

Introduced in GitLab 13.6.

Checks if CI/CD YAML configuration is valid. This endpoint has namespace specific context.

POST /projects/:id/ci/lint

Attribute	Type	Required	Description
`content`	string	yes	The CI/CD configuration content.
`dry_run`	boolean	no	Run pipeline creation simulation, or only do static check. This is false by default.

Example request:

curl --header "Content-Type: application/json" "https://gitlab.example.com/api/v4/projects/:id/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\"]}}"}'

Example responses:

Valid configuration:

{
  "valid": true,
  "merged_yaml": "---\n:test_job:\n  :script: echo 1\n",
  "errors": [],
  "warnings": []
}

Invalid configuration:

{
  "valid": false,
  "merged_yaml": "---\n:test_job:\n  :script: echo 1\n",
  "errors": [
    "jobs config should contain at least one visible job"
  ],
  "warnings": []
}

Validate a project's CI configuration

Introduced in GitLab 13.5.

Checks if a project's latest (HEAD of the project's default branch) .gitlab-ci.yml configuration is valid. This endpoint uses all namespace specific data available, including variables, local includes, and so on.

GET /projects/:id/ci/lint

Attribute	Type	Required	Description
`dry_run`	boolean	no	Run pipeline creation simulation, or only do static check.

Example request:

curl "https://gitlab.example.com/api/v4/projects/:id/ci/lint"

Example responses:

Valid configuration:

{
  "valid": true,
  "merged_yaml": "---\n:test_job:\n  :script: echo 1\n",
  "errors": [],
  "warnings": []
}

Invalid configuration:

{
  "valid": false,
  "merged_yaml": "---\n:test_job:\n  :script: echo 1\n",
  "errors": [
    "jobs config should contain at least one visible job"
  ],
  "warnings": []
}

Use jq to create and process YAML & JSON payloads

To POST a YAML configuration to the CI Lint endpoint, it must be properly escaped and JSON encoded. You can use jq and curl to escape and upload YAML to the GitLab API.

Escape YAML for JSON encoding

To escape quotes and encode your YAML in a format suitable for embedding within a JSON payload, you can use jq. For example, create a file named example-gitlab-ci.yml:

.api_test:
  rules:
    - if: '$CI_PIPELINE_SOURCE=="merge_request_event"'
      changes:
        - src/api/*
deploy:
  extends:
    - .api_test
  rules:
    - when: manual
      allow_failure: true
  script:
    - echo "hello world"

Next, use jq to escape and encode the YAML file into JSON:

jq --raw-input --slurp < example-gitlab-ci.yml

To escape and encode an input YAML file (example-gitlab-ci.yml), and POST it to the GitLab API using curl and jq in a one-line command:

jq --null-input --arg yaml "$(<example-gitlab-ci.yml)" '.content=$yaml' \
| curl "https://gitlab.com/api/v4/ci/lint?include_merged_yaml=true" \
--header 'Content-Type: application/json' \
--data @-

Parse a CI Lint response

To reformat the CI Lint response, you can use jq. You can pipe the CI Lint response to jq, or store the API response as a text file and provide it as an argument:

jq --raw-output '.merged_yaml | fromjson' <your_input_here>

Example input:

{"status":"valid","errors":[],"merged_yaml":"---\n:.api_test:\n  :rules:\n  - :if: $CI_PIPELINE_SOURCE==\"merge_request_event\"\n    :changes:\n    - src/api/*\n:deploy:\n  :rules:\n  - :when: manual\n    :allow_failure: true\n  :extends:\n  - \".api_test\"\n  :script:\n  - echo \"hello world\"\n"}

Becomes:

:.api_test:
  :rules:
  - :if: $CI_PIPELINE_SOURCE=="merge_request_event"
    :changes:
    - src/api/*
:deploy:
  :rules:
  - :when: manual
    :allow_failure: true
  :extends:
  - ".api_test"
  :script:
  - echo "hello world"

With a one-line command, you can:

Escape the YAML
Encode it in JSON
POST it to the API with curl
Format the response

jq --null-input --arg yaml "$(<example-gitlab-ci.yml)" '.content=$yaml' \
| curl "https://gitlab.com/api/v4/ci/lint?include_merged_yaml=true" \
--header 'Content-Type: application/json' --data @- \
| jq --raw-output '.merged_yaml | fromjson'
