Update Docker tag using Docker task on Azure DevOps pipeline

Question

I'm trying to change the tag of a Docker image using a Docker task on an Azure DevOps pipeline, without success.

Consider the following Docker image hosted on an Azure container registry:

My task is configured as follows:

$(DockerImageName) value is agents/standard-linux-docker2:310851

I'm trying to change the Docker image tag (e.g. to latest) but so far I wasn't able to make it work. I've also tried to set the arguments as well, without success.

Task fails with the following error message:

Error response from daemon: No such image: agents/standard-linux-docker2:310851

/usr/bin/docker failed with return code: 1

What am I missing here?

hm, can you try pulling that image first? mb it doesnt auth before tagging, so fails to find that image — 4c74356b41

Hi @4c74356b41, could you please elaborate? I'm fairly new to Docker, I'm still trying to understand how things work. Image agents/standard-linux-docker2:310851 was already pushed to Azure, now I just want to change the tag. The idea is to have different tags per environment, e.g. latest would correspond to the Production image. — Rui Jarimba

add a step with docker pull, before the docker tag step, so it downloads the image locally — 4c74356b41

@4c74356b41 what about the syntax of my push task above? How should I set the arguments? — Rui Jarimba

Try using Azure CLI Task. Run the following command and select the options in the image.

az acr import --name xxxxxacr --source xxxxxacr.azurecr.io/xxx/xxx-api:stage --image xxxxyyyyyyy/yyyyyyyy-api:prod --force
