What is your experience with GitLab Registry?

GitLab Registry is an integrated container image and package registry within GitLab that allows storing and managing Docker images and artifacts directly within the project.

Experience with GitLab Registry typically includes:

• Setting up CI/CD pipelines for automatic build and publish of Docker images to the registry.
• Managing image versions and tags.
• Using images from the registry in various environments (e.g., for deployment).

Example of a simple .gitlab-ci.yml for building and publishing a Docker image:

image: docker:latest
services:
  - docker:dind

stages:
  - build

build_image:
  stage: build
  script:
    - docker login -u "$CI_REGISTRY_USER" -p "$CI_REGISTRY_PASSWORD" $CI_REGISTRY
    - docker build -t $CI_REGISTRY_IMAGE:$CI_COMMIT_REF_NAME .
    - docker push $CI_REGISTRY_IMAGE:$CI_COMMIT_REF_NAME

This approach allows effective integration of containerization into development and delivery processes.
