azure webapp for container error trying to mount blob storage

Question

I am working on dockrized app which is deployed in azure with app service "webApp for containers"

i am trying to link a blob storage account to my app i already created storage account and linked it to the my app at "path mappings" tab.

but i keep getting error saying :

 Exception in multi-container config parsing: (Line: 13, Col: 15, Idx: 336) - (Line: 13, Col: 37, Idx: 358): Bind mount must start with ${WEBAPP_STORAGE_HOME}.

i want to use my own volume, i dont want to bind it to local host storage.

what am i doing wrong?

below is the configuration and the error of the compose file, i even removed all the other services just to make sure that there are no unexpected problems

version: '2'
services:     
    app:
        container_name: almaz-backend
        image: 'almazyregistry.azurecr.io/test/alamzo:latest'
        restart: always
        build: .
        ports:
            - '3000:3000'        
        environment:
            - NODE_ENV=production        
        volumes:               
            - AppDataMount/logs:/logs    
            - AppDataMount/public:/public

volumes:
 AppDataMount:

What are your path mappings settings (hide the storage account name) ? — CSharpRocks, Dec 01 '19 at 21:39

Why not give any response? Do you really want to solve the problem?! — Charles Xu, Dec 20 '19 at 06:41

Actually, what you had set to mount the volumes does not meet the rules in Azure Web App For Container. If you want to use the docker-compose file, it should be like this:

version: '3'
services:     
    app:
        container_name: almaz-backend
        image: 'almazyregistry.azurecr.io/test/alamzo:latest'
        restart: always
        build: .
        ports:
            - '3000:3000'        
        environment:
            - NODE_ENV=production        
        volumes:               
        - <custom-id1>:/logs/
        - <custom-id2>:/public/

And each volume needs one container in the storage. So for you, it needs two containers. You can use the CLI command to set the custom id like this:

az webapp config storage-account add --resource-group <group_name> --name <app_name> --custom-id <custom_id> --storage-type AzureBlob --share-name <share_name> --account-name <storage_account_name> --access-key "<access_key>" --mount-path <mount_path_directory>

its seems to stop throwing the previous error, but also seems to be ignored , files and logs are not visible in the storage account – Ananim Kaholim Dec 02 '19 at 11:00
@AnanimKaholim Do the files in the mount path exists in the image, or they the new files when the image comes into a container? – Charles Xu Dec 04 '19 at 02:06
nope there are no files just empty folder i prepared, both public and logs are empty. – Ananim Kaholim Dec 04 '19 at 14:41
@AnanimKaholim Can you share your image? I could take a test. – Charles Xu Dec 05 '19 at 01:29
@AnanimKaholim All things work perfectly on my side, I'm afraid you made the mistake. If you share the image, maybe I can test for you. – Charles Xu Dec 06 '19 at 02:05
