When booting up a memgraph container, both on azure container apps with a mounted fileshare or locally, with a mounted volume, i get a permission denied error.

It works in my docker compose when i define a volume, that is not mounted.

i tried setting permissions, both in the command and in an entry script. e.g.:

chmod -R 777 /var/lib/memgraph

this does NOT work:

services:
  app:
    build:
      context: .
      dockerfile: app/Dockerfile
    image: app:latest
    container_name: app
    volumes:
      - ./local_volume/app:/mnt/data
    ports:
      - "8000:8000"
    restart: always
    environment:
      - Environment=${Environment}
    depends_on:
      memgraph-mage:
        condition: service_healthy

  memgraph-mage:
    image: memgraph/memgraph-mage
    container_name: memgraph-mage
    ports:
      - "7687:7687"
      - "7444:7444"
    restart: always
    volumes:
      - ./local_volume/memgraph/data:/var/lib/memgraph
      - ./local_volume/memgraph/log:/var/log/memgraph
    healthcheck:
      test: ["CMD-SHELL", "echo 'RETURN 0;' | mgconsole || exit 1"]
      interval: 10s
      timeout: 5s
      retries: 3
      start_period: 0s
    environment:
      - MEMGRAPH_USER=${MEM_USER}
      - MEMGRAPH_PASSWORD=${MEM_PASSWORD}

networks:
  default:
    driver: bridge

this works fine:

services:
  app:
    build:
      context: .
      dockerfile: app/Dockerfile
    image: app:latest
    container_name: app
    volumes:
      - ./local_volume/app:/mnt/data
    ports:
      - "8000:8000"
    restart: always
    environment:
      - Environment=${Environment}
    depends_on:
      memgraph-mage:
        condition: service_healthy

  memgraph-mage:
    image: memgraph/memgraph-mage
    container_name: memgraph-mage
    ports:
      - "7687:7687"
      - "7444:7444"
    restart: always
    volumes:
      - mg_lib:/var/lib/memgraph
      - mg_log:/var/log/memgraph
    healthcheck:
      test: ["CMD-SHELL", "echo 'RETURN 0;' | mgconsole || exit 1"]
      interval: 10s
      timeout: 5s
      retries: 3
      start_period: 0s
    environment:
      - MEMGRAPH_USER=${MEM_USER}
      - MEMGRAPH_PASSWORD=${MEM_PASSWORD}

networks:
  default:
    driver: bridge

volumes:
    mg_lib:
    mg_log:

How can i set a memgraph container inside an azure container app?
