How to create Gitlab CI rules that are evaluated as AND instead of OR

Question

The following gitlab ci job will run if the variable $CI_COMMIT_TAG is set OR if the ./versions.txt file has changed.

Answer 1

From Docs:

In the following example:

We run the job manually if Dockerfile or any file in docker/scripts/ has changed AND $VAR == "string value". Otherwise, the job will not be included in the pipeline.

docker build:
      script: docker build -t my-image:$CI_COMMIT_REF_SLUG .
      rules:
        - if: '$VAR == "string value"'
          changes: # Will include the job and set to when:manual if any of the follow paths match a modified file.
          - Dockerfile
          - docker/scripts/*
          when: manual  

Your code will look something like this.

some-job:
  script:
    - echo "Do some fancy stuff.";
  rules:
    - if: $CI_COMMIT_TAG
      changes: 
        - versions.txt
      when: manual
