I recently got into CI/CD, and a good starting point for me was GitLab, since they provide an easy interface for that and i got started about what pipelines and stages are, but i have run into some kind of contradictory thought about GitLab CI running on Docker.

My app runs on Docker Compose. It contains (blah blah) that makes it easy to build & run containers. Each service in the Docker Compose creates a single Docker container, excepting the php-fpm one, which is able to do the thing called "horizontal scale", so I can scale it later.

I will use that Docker Compose for production, I am currently using it in development and I want to use it too in CI/CD pipelines.

However the .gitlab-ci.yml provides support for only one image, so I have to build it and push it to either their GitLab Registry or Docker Hub in order to pull it later in the CI/CD process.

How can I build my Docker Compose's service as a single image in order to push it to the Registry/Docker so I can pull it in the CI/CD?

My project contains a docker folder and a docker-compose.yml. In the docker folder, each service has its own separate directory (php-fpm, nginx, mysql, etc.) and each one (prepare yourself) contains a Dockerfile with build details, especially the php-fpm one (deps and libs are strong with this one)

Each service in the docker-compose.yml has a build context in each of their own folder.

If I was unclear, I can provide additonal info.

You don't need dind to run a docker-compose stack. You can run multiple docker-compose up commands.

  stage: test
    - docker-compose -p $CI_JOB_ID up -d
    - docker-compose -p $CI_JOB_ID exec -T /run/your/test/
    - docker-compose -p $CI_JOB_ID down -v --remove-orphans || true

Building Docker images with GitLab CI/CD, You can add as many services you need to .gitlab-ci.yml or manually modify config.toml . Any image found at Docker Hub or your private Container Registry can  Push multiple images with a single docker-compose push command. Vanilla Docker in GitLab CI/CD. Before going into how to setup Docker Compose in a pipeline, let's take a quick look at how to use plain Docker-CLI in GitLab CI/CD.

Using Docker images, Description Developers create multiple containers based on the same It seems that I can't push a docker image to the new registry when I specify the project as such - a typical scenario when using docker-compose .

How to setup and proper maintainable workflow for managing your own Docker images: automate everything from your commit to the hub.

However the .gitlab-ci.yml provides support for only one image

This is not true. From the official documentation:

Your image will be named after the following scheme:

<registry URL>/<namespace>/<project>/<image>

GitLab supports up to three levels of image repository names. Following examples of image tags are valid:

So the solution to your problem is simple - just build individual images and push them to GitLab container registry under different image name. The following config should give you an idea:

.template: &build_template
  image: docker:stable
    - docker:dind
    - docker pull $CI_REGISTRY_IMAGE/$IMAGE_NAME:latest || true
    - if [ -z ${CI_COMMIT_TAG+x} ];
      then docker build
        --cache-from $CI_REGISTRY_IMAGE/$IMAGE_NAME:latest
        --file $DOCKERFILE_NAME
        --tag $CI_REGISTRY_IMAGE/$IMAGE_NAME:latest . ;
      else docker build
        --cache-from $CI_REGISTRY_IMAGE/$IMAGE_NAME:latest
        --file $DOCKERFILE_NAME
        --tag $CI_REGISTRY_IMAGE/$IMAGE_NAME:latest . ;
    - if [ -z ${CI_COMMIT_TAG+x} ]; then
    - docker push $CI_REGISTRY_IMAGE/$IMAGE_NAME:latest

  <<: *build_template
    IMAGE_NAME: image1
    DOCKERFILE_NAME: Dockerfile.1

  <<: *build_template
    IMAGE_NAME: image2
    DOCKERFILE_NAME: Dockerfile.2

And you should be able to pull the same image using $CI_REGISTRY_IMAGE/$IMAGE_NAME:$CI_COMMIT_SHA in later pipeline jobs or your compose file (provided that the variables are passed to where you run your compose file).

Support specifying a multi-level image name in Gitlab Container , gitlab-ci.yml provides support for only one image, so I have to build it and push it to either their GitLab Registry or Docker Hub in order to pull it  You can specify a tagged image to be used as a cache source for the docker build command by using the --cache-from argument.
