Update all Docker images

update-images.sh

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

I find that I have multiple versions of an image, adding a uniq -u squashes it down to unique lines

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

update from current TAG

# docker images | grep -v REPOSITORY | awk '{printf("%s:%s\n", $1, $2)}' | xargs -L1 docker pull

update images with tag latest

docker images --format "{{.Repository}}:{{.Tag}}" | grep :latest | xargs -L1 docker pull

This doesn't seem to work anymore, any update? Btw please ping me with @enoch85

@enoch85, I just used Brayden's command with success

To update the docker images with the current tag use this command:
docker images | grep -v REPOSITORY | awk '{printf $1; printf ":"; print $2}' | xargs -L1 docker pull

Update images with current tag @hetykai:

docker images --format "{{.Repository}}:{{.Tag}}" | xargs -L1 docker pull

I have been using this one:

docker images --format "{{.Repository}}:{{.Tag}}" | grep --invert-match '<none>' | xargs -L1 docker pull

It removes the untagged images and pulls all by tag.

For PowerShell users this could be helpful:

docker images --format "{{.Repository}}:{{.Tag}}" | ForEach-Object { docker pull $_ }
