How do I use the warn section in a pipeline as code?

Modified on Wed, 21 Jun 2023 at 02:54 PM

To use the warn section in a GitLab pipeline as code, you can define a step that triggers a warning message in the pipeline under certain conditions. This can be useful for scenarios where you want to highlight potential issues or provide informative messages without failing the entire pipeline.

Here's an example of how you can use the warn section:

  - build
  - test

  stage: build
    - echo "Building..."

  stage: test
    - echo "Running tests..."
    - if: '$CI_COMMIT_REF_NAME == "master"'
        message: "Warning: Running tests on the master branch"

In the above example:

The pipeline consists of two stages: build and test.

The build stage simply echoes "Building..." as an example.

The test stage runs tests using the script keyword.

The rules section is used to define a condition for the test stage.

The if condition checks if the current branch is master.

If the condition is met, the warn section is triggered.

The message field within the warn section provides a warning message to be displayed in the pipeline logs


By using the warn section, you can generate warning messages in the pipeline logs based on specific conditions. This can help draw attention to potential issues or provide additional information without causing the pipeline to fail.
