Move docker images from one acr to another (docker images --format option not executing docker tag , docker push )

Question

I am trying to move images from one acr to another acr. (also any alternate method to do this please suggest)

I am using shell script and I have declared variables for one image to test it ( however i have 20+ images ) "sourceacr" image="myimage" minimum_version="1.0.0" "targetacr"

steps followed:

docker pull $sourceacr/image --all-tags

then filter since the minimum version , re-tag it and push to target acr

my command is

docker images $sourceacr/$image --filter "since=$sourceacr/$image:$minimum_version" --format "docker tag {{.Repository}}:{{.Tag}} $targetacr/$image:{{.Tag}} | docker push $targetacr/$image:{{.Tag}}"

I get output as command that is used after --format option but it doesn't execute the tag and push commands. Any help is appreciated!

current output:

docker tag source.azurecr.io/myimage:1.0.0 target.azureacr.io/myimage:1.0.0 | docker push target.azureacr.io/myimage:1.0.0

Have you tried using xargs to take in standard input and give it as an argument to docker? — Nick ODell, Jul 29 '21 at 15:30

The way you have your command, it's basically outputting the docker commands in the terminal. You need to execute them as command, try like this:

docker images $sourceacr/$image  --filter "since=$sourceacr/$image:$minimum_version" --format "docker tag {{.Repository}}:{{.Tag}} $targetacr/$image:{{.Tag}} | docker push $targetacr/$image:{{.Tag}}" | bash

or using shell:

docker images $sourceacr/$image  --filter "since=$sourceacr/$image:$minimum_version" --format "docker tag {{.Repository}}:{{.Tag}} $targetacr/$image:{{.Tag}} | docker push $targetacr/$image:{{.Tag}}" | sh

Thanks but i still get similar output but with | Bash – gmpy1990 Jul 29 '21 at 16:20
Can you please edit your original post with the command and output from your shell? – CaioT Jul 29 '21 at 16:28
The output looks correct. So you're saying with the | bash is not executing the output commands? – CaioT Jul 29 '21 at 17:15
yes correct. it just gives me additional | bash in my output but doesn't execute them. – gmpy1990 Jul 29 '21 at 17:19
My apologies, I had included the | bash between the double quotes for the --format field. I edited my post with the correct formatting. Can you please try again and let me know? – CaioT Jul 29 '21 at 17:21
thanks much . it worked. ( i am using shell so i have added | sh) – gmpy1990 Jul 30 '21 at 14:02
