dive is a Docker image explorer. This is a very handy tool when you are trying to figure out how a Docker image was built and what’s in it, and you don’t have the original Dockerfile.
It uses the meta information for each layer to show you which command was used to create the layer, and which files were added, removed, or changed.
Additionally, you can use dive to make sure your Docker images are optimized and their size is under control. You can even integrate dive into your CI/CD pipeline!
