How do I push to a repo from within a gitlab CI pipeline?

Question

In my CI pipeline I am generating an artifact public/graph.png that visualises some aspect of my code. In a later step I want to commit that to the repo from wi

Answer 1

I can commit from Gitlab-CI with a selected user with a minor change based on tsr's answer https://stackoverflow.com/a/57800614/5269825 :

# set remote URL to https://oauth2:@server.com/project.git
CI_PUSH_REPO=`echo "$CI_REPOSITORY_URL $ACCESS_TOKEN_PARAM" | sed 's/^.*\(@.*\)\s\(.*\)/https:\/\/oauth2:\2\1/g'`
git config http.sslverify false
git remote set-url --push origin "${CI_PUSH_REPO}"
git config user.name "Token Owner"
git config user.email "tokenowner@email.com"

# runner runs on a detached HEAD, create a temporary local branch for editing
git checkout -b ci_processing
# make your changes

# push changes
# always return true so that the build does not fail if there are no changes
git push origin ci_processing:${CI_BUILD_REF_NAME} || true

The ACCESS_TOKEN_PARAM must be configured at the project's CI/CD Variables configuration.

The idea of using Oauth2 and Access Token was taken from https://stackoverflow.com/a/52074198/5269825 and https://stackoverflow.com/a/52154378/5269825.

Also, pushing changes can trigger a new pipeline!
