Hands-On Auto DevOps with GitLab CI - Building and Testing with Docker

The video tutorial covers building and testing with Docker in GitLab CI. It explains how to configure GitLab CI to build Docker images, use built-in variables, and push images to the GitLab Container Registry. The tutorial introduces the Docker in Docker approach, where a Docker daemon runs inside a Docker container, allowing for standard Docker commands. It also discusses the use of GitLab's built-in variables and the CI registry for managing Docker images. The video concludes with a look at the build process and a preview of future topics, including build stages and dependencies.
