Get latest tag in .gitlab-ci.yml for Docker build

I want to add a tag when building a Docker image, I'm doing this so far but I do not know how to get the latest tag on the repository being deployed.

docker build -t company/app .

My goal

docker build -t company/app:$LATEST_TAG_IN_REPO? .

The pre-defined variable $CI_COMMIT_TAG is empty if no git tag points to the current commit in the pipeline. If you either want the current tag or the current SHA of the commit (as a fallback), you can use IMAGE_VERSION=${CI_COMMIT_TAG:-"$CI_COMMIT_SHORT_SHA"}

Since you're looking for the "latest" git tag which is an ancestor of the currently building commit you probably want to use

git describe --tags --abbrev=0

to get it and use it like:

docker build -t company/app:$(git describe --tags --abbrev=0) .

You can try using $CI_COMMIT_TAG or $CI_COMMIT_REF_NAME, this is part of the predefined variables accessible during builds.

If you want to see what are all the available environment variables during build step this should work as one of your jobs:

script:
    - env
