stanislavb/docker-image-diff repository overview

⁠Docker image diff

Check if your locally cached image is the same as on Docker Hub. Takes image and optional tag as input. If tag is omitted, 'latest' is assumed.

Return codes:

• 0 if images are the same
• 1 on error (like registry being offline)
• 2 if images differ or image not locally cached
• 3 if image not found in registry

⁠Limitations

• Errors out on SSL verification when using boot2docker.
• Untested with private registry.

⁠Build it yourself

make build

⁠Run it from Docker Hub

docker run --rm -i -v /var/run/docker.sock:/var/run/docker.sock stanislavb/docker-image-diff python:3-onbuild
