Empty predefined variables env pipeline

GitLab CI/CD

Hello, can I count on your help?

I’m having problems trying to use rules with manual condition. I noticed that the variables that I try to use in the “if rules” are returning empty. I verified this by running the “env” command in the script: from the pipeline:

Only a few return results, but they’re not the results I’d like:

$ echo $CI_MERGE_REQUEST_TITLE
$ echo $CI_COMMIT_DESCRIPTION
$CI_COMMIT_DESCRIPTION
$ echo $CI_COMMIT_MESSAGE
Update .gitlab-ci.yml
$ echo $CI_COMMIT_TITLE
Update .gitlab-ci.yml
$ echo $CI_PROJECT_TITLE
Repo Helm Charts
$ echo $TRIGGER_PAYLOAD
$ echo $CI_MERGE_REQUEST_APPROVED
$ echo $CI_MERGE_REQUEST_LABELS
$ echo $CI_MERGE_REQUEST_EVENT_TYPE

I believe it has something to do with me opening the Merge Request via curl inside the JOB.

Contextualizing my pipeline:

  • It is a pipeline to serve as a central repository of charts that are developed by other devs. In this repository, the charts are organized in folders according to the name of each team.

I’m using multi-project pipelines.

There are basically two jobs.
1 - Clone the dev repository and send the chart to the central chart repository that is in a different project from the dev.
2 - Push the chart to a chartmuseum.

No Job 1 - I’m consuming the merge request API, and I’m trying to enable a condition so that the job runs according to the labels informed in the open merge request. However, without success. Apparently the variables I try to use are not being satisfied with the values referred to in the merge request data header.

Below is the command used to open the Merge Request:

push-repository-projects:
stage: catalog
before_script:
- TMPDIR=$(mktemp -d)
script:
- cd $TMPDIR

clona repositorio de chart desenvolvido por outro dev

- git clone https://"$USR_TOKEN":"$PWD_TOKEN"@gitlab.com/$PROJECT_PATH

…
- git add .

commit to another project - central chart repository

- git commit -m "Pipeline Merge Request - $PROJECT_NAME "
- git push https://"$USR_TOKEN":"$PWD_TOKEN"@gitlab.com/$CI_PROJECT_PATH

#open merge request

      curl --request POST https://gitlab.com/api/v4/projects/${PROJECT_ID}/merge_requests --header "PRIVATE-TOKEN: ${PWD_TOKEN}" \
      --header 'Content-Type: application/json' \
      --data "{
                \"id\": \"${PROJECT_ID}\",
                \"title\": \"${PROJECT_NAME}\",
                \"source_branch\": \"${PROJECT_NAME}\",
                \"labels\": [ \"public\",\"verified\" ],
                \"remove_source_branch\": true,                
                \"target_branch\": \"main\"
              }"

In my rules, I’m trying to say that if my merge has a label with the word “public” it depends on a manual action.

rules:
- if: ‘$CI_PIPELINE_SOURCE == “push” || $CI_PIPELINE_SOURCE == “merge_request_event”’
when: never
- if: ‘$CI_MERGE_REQUEST_LABELS =~ “public”’
when: manual
- when: always
