Infinite push in a Job of a pipeline in GitLab CI - gitlab

Question

I manage the next diagram in aws infrastructure with repos and submodules in gitlab and pipelines en CI.
Pipeline Update Git Submodules - GitLab CI
Currently, I require update every project when his update a submodule by the pipeline with Job for this from a runner Shell.
But I don't have a idea how to finish this request?
I share my codes in the pipeline.
Submodules:
variables:
TEST_VAR: "Begin - Update all git submodule in projects."
stages:
- build
- triggers
job1:
stage: build
script:
- echo $TEST_VAR
trigger_A:
stage: triggers
when: on_success
trigger:
project: pruebas-it/proyecto_a
branch: main
trigger_B:
stage: triggers
when: on_success
trigger:
project: pruebas-it/proyecto_b
branch: main
Projects:
variables:
TEST_VAR: "Begin - Update all git submodule in projects."
COMMIT: "GIT"
CHANGES: $(git status --porcelain | wc -l)
stages:
- build
- test
- deploy
job1:
stage: build
script:
- echo $TEST_VAR
- echo $COMMIT
job2:
stage: test
extends: .deploy-dev
only:
variables: [ $CI_PIPELINE_SOURCE == "push" ]
job3:
stage: deploy
variables:
DOCKERFILES_DIR-A: './submodulo-a' # This variable should not have a trailing '/' character
DOCKERFILES_DIR-B: './submodulo-b' # This variable should not have a trailing '/' character
rules:
- if: $CI_COMMIT_BRANCH
changes:
compare_to: 'refs/heads/main'
paths:
- '$DOCKERFILES_DIR-A/*'
- '$DOCKERFILES_DIR-B/*'
stage: deploy
before_script:
- 'which ssh-agent || ( apt-get update -y && apt-get install openssh-client -y )'
- eval $(ssh-agent -s)
- echo "$SSH_PRIVATE_KEY" | tr -d '\r' | ssh-add - > /dev/null
- ssh -T git#gitlab.com
- mkdir -p ~/.ssh
- chmod 700 ~/.ssh
- git config --global user.name "${GITLAB_USER_NAME}"
- git config --global user.email "${GITLAB_USER_EMAIL}"
- echo "${CI_COMMIT_MESSAGE}" "${GITLAB_USER_EMAIL}" "${CI_REPOSITORY_URL}" "$CI_SERVER_HOST"
- url_host=$(echo "${CI_REPOSITORY_URL}" | sed -e 's|https\?://gitlab-ci-token:.*#|ssh://git#|g')
- echo "${url_host}"
- ssh-keyscan "$CI_SERVER_HOST" >> ~/.ssh/known_hosts
- chmod 644 ~/.ssh/known_hosts
- git submodule sync
- git submodule update --remote
script:
- git branch
- git config remote.origin.fetch "+refs/heads/*:refs/remotes/origin/*"
- git fetch origin
- git checkout main
- git config pull.rebase false
- git pull
- echo 1 >> update.txt
- git status
- git add -A
- git commit -m "$COMMIT"
- git push "${url_host}"
.deploy-dev:
script: exit
The output of the before is: that push the commit for update the submodules in every project, I have a infinite push of running Jobs in a cicle without finish the pipeline.
Trigger without stage deploy
Somebody can help me to undestand, why I don't have a exit to goal with this? please!!!
Thank's for the attention to the present.
I Try with a trigger from update submodule launch a trigger over the two projects in the polirepo for common folder, without succesfull for this.
I try use of variables states in push for trigger without nothing result. The Job not run over the pipeline with this conditional.
I try to use workflows with rules for this, but not finish.
I try use to regex in match, but the pipeline run a infinite push.
