Docker-compose: using azure file share like bind mount with volumes

Question

I have the below docker-compose.yml file where I am looking to use an azure file share with two specific paths on the share (share-data/nginx and share-data/config/nginx.conf) that should map to two locations in the container. When running docker compose up I am getting duplicate volume mount error. Why can't I use the below azure file share paths like one would with a bind mount?

version: '3.7'

services:

nginx:
  image: nginx
  volumes:
    - share-data/nginx:/opt/nginx
    - share-data/config/nginx.conf:/etc/nginx/nginx.conf 
  ports:
    - 80:80
    - 443:443

volumes:
  data:
    driver: azure_file
    driver_opts:
      share_name: share-data
      storage_account_name: storage-data

Hi @tewodros

• Azure file share volume mount requires the Linux container run as root

Below is the sample YAML template to Deploy container and mount volume

apiVersion: '2019-12-01'  
location: eastus  
name: file-share-demo  
properties:  
  containers:  
  - name: hellofiles  
    properties:  
      environmentVariables: []  
      image: mcr.microsoft.com/azuredocs/aci-hellofiles  
      ports:  
      - port: 80  
      resources:  
        requests:  
          cpu: 1.0  
          memoryInGB: 1.5  
      volumeMounts:  
      - mountPath: /aci/logs/  
        name: filesharevolume  
  osType: Linux  
  restartPolicy: Always  
  ipAddress:  
    type: Public  
    ports:  
      - port: 80  
    dnsNameLabel: aci-demo  
  volumes:  
  - name: filesharevolume  
    azureFile:  
      sharename: acishare  
      storageAccountName: <Storage account name>  
      storageAccountKey: <Storage account key>  
tags: {}  
type: Microsoft.ContainerInstance/containerGroups

Hello All,
I have storage account set up with SMB file share and I am having similar issues.
When I try this -

version: '3'

volumes:
postgres-db-volume:
azureFile:
sharename: ##
storageAccountName: ##
storageAccountKey: ##

I am getting an error as -
volumes.azureFile value 'sharename', 'storageAccountKey', 'storageAccountName' do not match any of the regexes: '^x-'

Is there any plugins/Docker Azure context I need to set up?
