[SOLVED] How can I push docker compose based images for Gitlab Registry Using CI/CD

Issue

I've linked Postgres DB & API images using docker-compose, its working in local, I've to push both image for gitlab registry Using CI/CD.

enter image description here

Solution

The gitlab docs cover how to build and push Docker images during CI quite well.

It is important to note/use the CI_REGISTRY_IMAGE variable. If the image name you try to push is different from CI_REGISTRY_IMAGE, the push will fail. If you want to have multiple images, you either need to label them in the tag ($CI_REGISTRY_IMAGE:db-$CI_COMMIT_REF_SLUG) or create a separate repo and manage the images there.
