Update all Docker Images at once

Update ( 2018 ):

As mentioned in the comments, you can by now also use the following syntax :

docker images --filter "dangling=false" --format "{{.Repository}}:{{.Tag}}" | xargs -L1 docker pull

This would then update all images that aren't currently dangling ( Images that show up with <none> as they aren't used any longer. You should clean those up regularly.

Original post ( 2014 ) :

For future quick reference, currently using this quick fix to update all Docker images to which we have repository access, on a specific host at once :

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

It might throw an error when it hits 'CONTAINER' and 'none' entries, as well as locally built images – however those can be of course ignored.

You can get rid of the first row and "" entries:
awk '(NR>1) && ($2!~/none/) {print $1}'

TAG information is also useful:
docker images | awk '(NR>1) && ($2!~/none/) {print $1":"$2}'| xargs -L1 docker pull

skip entries using awk:

docker images | awk '/^REPOSITORY|/ {next} {print $1}' | xargs -n 1 docker pull

also: in Docker version 1.8.1, build d12ea79 xargs uses option '-n' and not '-L'.

This will update the specific tags:

docker images | awk 'BEGIN {OFS=":";}NR<2 {next}{print $1, $2}' | xargs -L1 docker pull

You can also alias this in your ~/.zshrc or ~/.bashrc

alias dup="docker images | awk 'BEGIN {OFS=":";}NR<2 {next}{print $1, $2}' | xargs -L1 docker pull"

Xiol is pretty close, I use this:
docker images | awk '(NR>1) && ($2!~/none/) {print $1":"$2}' | xargs -L1 docker pull

Why use awk when docker images has both filtering and formatting built in:

docker images –filter "dangling=false" –format "{{.Repository}}:{{.Tag}}" | xargs -L1 docker pull
