I will explain my problem with a scenario to make it understandable.

What I have:

• main branch (default, protected): have .gitignore + locked cicd.yml
  file
• feature branch: copied from main and then added required feature
• .gitlab-ci.yml file contains build and deploy jobs for the project (needs merge request predefined variables– title + description)

The wanted scenario:

1. dev commits changes to feature branch and request a merge to main needs approval -> .gitlab-ci.yml doesn’t run
2. when request is approved then merged run .gitlab-ci.yml in main not feature using $CI_MERGE_REQUEST_* predefined variables (title and description)

I have tried the follwing workflow rules

rules:
    - if: $CI_PIPELINE_SOURCE == 'merge_request_event' && $CI_MERGE_REQUEST_APPROVED && $CI_COMMIT_BRANCH == $CI_DEFAULT_BRANCH && $CI_MERGE_REQUEST_TITLE =~ /^vd+(.d+){2}$/ && $CI_MERGE_REQUEST_DESCRIPTION != "" && $CI_MERGE_REQUEST_DESCRIPTION =~ $MERGE_REQUEST_DESC_PATTERN && $CI_MERGE_REQUEST_EVENT_TYPE == "merged_result"

I need to check $CI_MERGE_REQUEST_TITLE and $CI_MERGE_REQUEST_DESCRIPTION so they can’t be removed (they are also used to build the image $CI_MERGE_REQUEST_TITLE is image tag)

is it possible to achieve this scenario? if not can you suggest a workaround

thank you in advance
