azure - I can´t pull image from azure ACR

Question

This is my first time using azure, I made a Pipeline in DevOps that creates images from dockerfile and pushes them to my ACR. Then I created a multi-container web app use docker-compose and connected my ACR to the web app. But the web app can't pull the images from the ACR. I don't know what I am doing wrong.

I am getting errors when I try to pull images from ACR in multi container web app.

Errors:

2019-11-28 19:27:46.755 INFO  - Pulling image: [registry-name].azurecr.io/server

Answer 1

First of all, the error shows that it cannot find the [registry-name].azurecr.io/server image with latest tag. So if your image does exist, then the problem is the tag.

If you do not add the tag for your image, it will pull the latest tag in default generally. The logs show like this:

But add a special tag for the image is better than no tag. If you want to get the latest image from the ACR, then always add the latest tag when push the image, do the same when you use that image.
