Web app for Multi-container: cannot map single file from host to container using Volumes of docker-compose and Azure Share

Question

Hi,

I'm using Azure Web app for Multi-container (Preview) to run a docker-compose file that run multiple containers.

Inside this docker-compose I have some references to external yaml configuration files (for example otel-collector, prometheus, etc).

I cannot find a way to map single file from host to container using Volumes of docker-compose.

I created an Azure Share connected to my Web App where I hosted the yaml configuration files.

Then in my docker-compose I wrote something like this:

volumes:

- otelshare/otel-collector-config.yaml:/etc/otel-collector-config.yaml

where otelshare is the name of my azure share.

WEBSITES_ENABLE_APP_SERVICE_STORAGE is setted to true.

I got this error:

Exception in multi-container config parsing: YamlException: (Line: 10, Col: 9, Idx: 262) - (Line: 10, Col: 77, Idx: 330): Bind mount must start with ${WEBAPP_STORAGE_HOME}.

Here is the full docker-compose just to give you more context:

version: '3.8'

services:

otel-collector-azure:

image: otel/opentelemetry-collector-contrib:latest

ports:

- "4317:4317"

- "4318:4318"

command: ['--config=/etc/otel-collector-config.yaml']

volumes:

- otelshare/otel-collector-config.yaml:/etc/otel-collector-config.yaml

volumes:

data:

driver: azure_file

driver_opts:

share_name: otelshare

storage_account_name: mystoragetest

Can anyone help me?
