Docker missing Image
If you have lost and image in docker this might help you recover it!
first run
docker image ls -a
your image is not displayed don't panic!
If you can't see the image but when you try and pull the image docker says - your image is up to date! This means you have a corrupt file! The easiest way to recover the image is to pull the image to another machine.
docker image save -o /tmp/saveOfMyImage image/name
When you load this on to your original machine with
docker load -i /tmp/saveOfMyImage
Docker will complain that files already exist, simply rename the file and repeat untill your image is loaded then run
docker image ls -a
Your image should have reappeared plus and incremented number version and maybe some hidden images too
