Update all Docker images

My work’s wifi is much faster than my 4G connection, so periodically I want to update all my docker images on my personal laptop while at work.

As I want to just set it going and then forget about it, I use the following one liner to do a docker pull against each image on my local machine:

docker images | grep -v REPOSITORY | awk '{print $1}'| xargs -L1 docker pull

If you only want to fetch the versions you have the tags for:

docker images | grep -v REPOSITORY | awk '{ if ($2 != "<none>") { print $1":"$2 } else { print $1 } }' | xargs -L1 docker pull

Now if only I could get git bash to do TTY properly so I get the pretty download indicators too :(
