Change gitlab CI/CD exit code

Question

I'm using docker to run a program as part of the CI/CD process. at the program, if the exit code is 2 I don't want the CI/CD to fail and only get a warning.

added this to the gitlab-ci.yml file:

  allow_failure:
    exit_codes: 
      - 2

but even tho the docker exit code is (2) at the pipeline I'm getting ERROR: Job failed: exit code 1

How can I change the error code of the pipeline to be like as the docker error code?

Thanks.

Answer 1

With the allow_failure keyword, your job is allowed to fail. It means that it won't failed if the specified exit_code resulted.

Your job will still have an exit code, but it will be marked in warning in your pipeline instead of failed

As an example, I made a simple job :

stages:
    - test

test_error_code:
    stage: test
    image: alpine:3.15.4
    script:
        - echo "bienvenuto"
        - exit 2
    allow_failure:
        exit_codes: 2

After adding the last two line, the pipeline moved to status warning : See pipeline picture

Hope it helps you!
