This document summarizes a presentation about managing Docker images with Concourse. It discusses building Docker images from a Dockerfile, triggering image builds when the Dockerfile or dependencies change. It also covers storing and pushing images, and using a Concourse pipeline to check for new images and code commits, rebuild images, tag images and the code repository with the new version.
