Change Management for Containers

Container-diff is a versatile tool designed to analyze and compare container images, offering functionalities beyond simple diffing. It allows users to inspect container images on macOS, Linux, and Windows, revealing installed packages, filesystem contents, and the commands that generated the images. The tool provides various test modes such as size, packages, filesystem, and layer history, enabling detailed insights into the image structure. These capabilities extend to comparing different images, which is particularly useful for generating changelogs, troubleshooting containers by identifying changes between healthy and failing versions, and test-driving new containers by assessing the impact of modifications. Container-diff supports customization through output templates and can be integrated into automated CI/CD workflows to monitor changes and ensure stable deployments by setting thresholds for acceptable image alterations.
