dive: a docker image layer explorer

by

https://github.com/wagoodman/dive

A tool for exploring the contents of a docker image, and each layer within that image. It is aimed at folks that are trying to identify ways to shrink their docker image. It reports on how efficient your image is and lists out each file that may be leading to inefficiencies (e.g. when adding a file in one layer and later removing it... this file still takes up space in the image).

  2. I get the following error when trying to open an image
    > open /home/wagoodman/Downloads/image/image.tar: no such file or directory

  3. Neat idea, I get an error though

    “`
    ❯ dive jenkins/jenkins

    Opened an [issue](https://github.com/wagoodman/dive/issues/28) for it.

    I’m running debian 9.5 in WSL on Windows 10. Shell is zsh 5.3.1

  5. Ahhhh yes this is nice. I’ve pretty much just gotten into the habit of doing crap like `docker exec sh` and just futzing around. That looks so much better.
