Docker.img almost full after nuking the last one?

My docker image was full and my containers wouldn't start so I deleted it and started a new one. It is 33GB and I only have 2.8GB free. I have included a picture of my containers.

I don't really have that much installed. How can I find out what is taking all of my space?

You have folders mapped incorrectly somewhere and data is being written to the docker image instead of to your array. 

 

You can try

du -xh --max-depth=1 /var/lib/docker|sort -hr

and that should tell what what folders are consuming the most space in your image.

 

Mine looks like this, removing the -x flag allows it to cross filesystem boundaries so that will show files in your Docker subvolumes.

This is what I get.

Nothing seems to be taking up too much space.
