About:
container-diff is a command-line tool that facilitates comparing Docker container images across various dimensions. It analyzes differences between images at the filesystem, package manager, and apt/yum level. This utility helps developers understand image changes, optimize layers, and debug build issues effectively.
Key Features:
  • Supports diffing images by filesystem, apt, and pip packages
  • Compares local images, remote images, and tar archives
  • Outputs results in human-readable or structured JSON format
  • Integrates with Docker and containerd runtimes
Use Cases:
  • Debugging why a new image build is larger than expected
  • Verifying that security patches were applied correctly in container layers
  • Auditing changes between development and production container versions
Alternatives:
  • Dive – Dive focuses on exploring Docker image layers interactively, whereas container-diff specializes in automated comparisons between two images.
  • Hadolint – Hadolint lints Dockerfiles for best practices, while container-diff analyzes the resulting built images for actual content differences.
