container-diff - an Open Source Tool from Google for Analyzing Differences Between Docker Images
Google released an open source project called container-diff which can be used to analyze differences between Docker images. It supports file-system differences and is aware of changes brought about by the apt, npm and pip package managers.
Dockerfiles are used to create and make additions to container images. A change in the Dockerfile followed by a rebuild leads to the creation of a new image. Differences between Dockerfile versions can be easily seen, usually by using the source control system’s diff tool, since they are plain text. However, it is difficult to visualize or list down the exact changes that occurred in the image as a result of a new command in the Dockerfile. This can become a challenge when the application being packaged in the image has dependencies on specific versions of other software, and there are downstream dependencies that make it complex to track what will get installed as a result. Untracked dependencies can also lead to unnecessary bloating of the image, leading to slower download times.
