Script to save all images from a docker-compose.yml file

gistfile1.txt

#!/bin/bash

mkdir -p out

for img in `grep image $1| sed -e 's/^.*image\: //g'`;
do
    cleanname=${img/\//-}
    tag=`docker images | grep $img | awk '{print $2}'`
    echo "Exporting image: $img, tag:$tag ($cleanname)..."
    docker save $img -o out/$cleanname.tar
    ls -lah out/$cleanname.tar
    tar -czvf out/$cleanname.tgz out/$cleanname.tar
    rm -rf out/$cleanname.tar
done

#!/bin/bash

for img in $(docker-compose config | awk '{if ($1 == "image:") print $2;}'); do
  images="$images $img"
done

docker save -o services.img $images

powershell

$images = @(); docker-compose config | ?{$_ -match "image:.*$"} | %{$images += ($_ -replace "image: ", "").Trim()}; docker save -o services.img $images

docker save -o services.img $images

Excellent
You saved my time

@hlavki solution as a one liner

docker save -o docker-images.tar $(docker-compose config | awk '{if ($1 == "image:") print $2;}' ORS=" ")

for img in $(docker-compose config | awk '{if ($1 == "image:") print $2;}'); do
  images="$images $img"
done

docker save -o services.img $images

And then, how can I use the file services.img?
I want to use 'docker load ' to load these images.
The first step is to unzip service.img?

@McPo ORS=" " can be dropped here.

docker save -o docker-images.tar $(docker-compose config | awk '{if ($1 == "image:") print $2;}')

for img in $(docker-compose config | awk '{if ($1 == "image:") print $2;}'); do
  images="$images $img"
done

docker save -o services.img $images

docker load < services.img

🙂

Compose V2 offers --images to list all images (even the ones build by the compose file).

#!/bin/bash

for img in $(docker compose config --images); do
  images="$images $img"
done

docker save -o services.img $images

powershell

$images = @(); docker-compose config | ?{$_ -match "image:.*$"} | %{$images += ($_ -replace "image: ", "").Trim()}; docker save -o services.img $images

@daveneeley You helped a lot thanks

aggregating all the kindness discussion above:
docker save -o services.img $(docker compose config --images)
