What is a container registry in GitLab?

A container registry in GitLab is primarily designed as a service for building, storing, and managing Docker images. This functionality allows developers to create containerized applications with Docker and manage those images within the GitLab ecosystem. By integrating the registry into the workflow, teams can build Docker images directly in their CI/CD pipelines, push them to the registry, and then pull them for deployment as needed.

The ability to store and version your Docker images simplifies the deployment process and enhances collaboration among team members, as they can access a centralized repository of images. This functionality supports continuous integration and continuous deployment (CI/CD) practices by providing the necessary components to build, test, and release applications in containers.

Other options do not pertain directly to the core function of a container registry. Version control, bug tracking, and hosting static websites are distinct features within GitLab that serve different purposes, focusing on source code management, issue tracking, and web hosting respectively.
