Deploy azure container registry images into an azure web app with docker-compose

Question

I'm trying to run a multicontainer web app based in two images that I stored in an azure container registry (launched with a docker compose yml custom file) but it fails because the docker-compose proccess cannot get the images due to an "unauthorized: autentication required" response. Both the container registry and the web app belongs to the same resource group.

How can we solve this problem? Thanks in advance.

So it can be solved via panel.azure.com

You need to configure authentication for the webapp, by default it can only pull public images.

this is the sample command to do that:

az webapp config container set --name <app_name> 
       --resource-group myResourceGroup 
       --docker-custom-image-name <azure-container-registry-name>.azurecr.io/mydockerimage 
       --docker-registry-server-url https://<azure-container-registry-name>.azurecr.io 
       --docker-registry-server-user <registry-username> 
       --docker-registry-server-password <password>
