Capture GitLab pipeline error somehow for next job to use-CodePudding

# Stage to pull and push image
job1:
  stage: job1


  allow_failure: true

  script:

    # Pull image and save success
    - docker pull ${SOURCE_IMAGEURI}:${TAG}

    ...

    - docker tag ${SOURCE_IMAGEURI}:${TAG} ${TARGET_IMAGEURI}:${TAG} 
    
    # Job might fail here due to not enough permissions which is what I want to happen
    - docker push ${TARGET_IMAGEURI}:${TAG} 

    - echo "Error Message" > curldata.txt
  artifacts:
    when: always
    paths:
      - curldata.txt

job2:
  stage: job2
  script:

    # Do something with the error that happened in job1

  when: always
  dependencies:
    - job1

So above is a part of a job that pulls and pushes an image. Sometimes the image will fail to push though as a safety step due to lack of permissions. How would I capture the error that happens so that I can send that artifacts to the next feedback job. This job will send the information to the user so he/she knows that they didnt have enough permissions.

CodePudding user response：

You can tee the (stderr) output of the command to a file and artifact the file.

script:
  # ...
  # show output of the command and store stderr to text file
  - docker push ${TARGET_IMAGEURI}:${TAG} 2> >(tee stderr.txt)
artifacts:
  paths:
    - stderr.txt
  when: always

If you need some logic to happen after the error, you can use and/or logic gates.

docker push ${TARGET_IMAGEURI}:${TAG} || echo "do this if it fails" > error.txt && exit 1

There's more to be said about robust error handling in bash, but those are some basic ideas you can use.
