Thanks for the tip! In case you are still looking for a solution, I got this to work using some help from this guide and have an example set up on my GitLab repo.
This is what my .gitlab-ci.yml looks like:
build:
image: ctornau/latex
stage: build
script:
- latexmk -pdf -pdflatex="xelatex -interaction=nonstopmode" -use-make *.tex
artifacts:
when: on_success
paths:
- ./*.pdf
expire_in: 5 min # might not need this if deploy works
deploy:
stage: deploy
before_script:
- 'which ssh-agent || ( apt-get update -qy && apt-get install openssh-client -qqy )'
- eval `ssh-agent -s`
- echo "${SSH_PRIVATE_KEY}" | tr -d '\r' | ssh-add - > /dev/null # add ssh ke
- mkdir -p ~/.ssh
- chmod 700 ~/.ssh
- echo "$SSH_PUBLIC_KEY" >> ~/.ssh/id_rsa.pub
- '[[ -f /.dockerenv ]] && echo -e "Host *\n\tStrictHostKeyChecking no\n\n" > ~/.ssh/config'
script:
- git config --global user.email "${CI_EMAIL}"
- git config --global user.name "${CI_USERNAME}"
- git add -f *.pdf # Force add PDF since we .gitignored it
- git commit -m "Compiled PDF from $CI_COMMIT_SHORT_SHA [skip ci]" || echo "No changes, nothing to commit!"
- git remote rm origin && git remote add origin git@gitlab.com:$CI_PROJECT_PATH.git
- git push origin HEAD:$CI_COMMIT_REF_NAME # Pushes to the same branch as the trigger
