Dive – A tool for exploring each layer in a Docker image
This is amazing, thanks for sharing it! A very useful feature that I always missed but never actually tough about.I've had a hard time understanding the slices on the beginning will be very useful for troubleshooting bad images also while optimizing image sizes.Can probably help to understand problems like the one bug where the image size got almost a 2x increase after a CHOWN, because the slice is added again with different owner ( I think ;) ) would be so much easier to see with this.Ref for the old bug
