Hi All,

I am trying to spin up a Grafana Loki instance that is going to persist logs in Azure Blob Storage. To verify the functionality I am doing this locally with the below settings:

docker compose:

version: '3.8'

services:
  nginx-app:
    container_name: nginx-app
    image: nginx
    ports:
      - 8080:80
    networks:
      - app

  grafana:
    image: grafana/grafana:latest
    ports:
      - 3000:3000
    volumes:
      - ./config/grafana-datasources.yaml:/etc/grafana/provisioning/datasources/datasources.yaml
    environment:
      - GF_AUTH_ANONYMOUS_ENABLED=true
      - GF_AUTH_ANONYMOUS_ORG_ROLE=Admin
      - GF_AUTH_DISABLE_LOGIN_FORM=true
    networks:
      - app

  loki:
    image: grafana/loki:2.4.1
    user: root
    ports:
      - 3100:3100
    command: -print-config-stderr -config.expand-env=true -config.file=/etc/loki/local-config.yaml
    volumes:
      - ./config/loki/loki-config.yaml:/etc/loki/local-config.yaml
    networks:
      - app
  # promtail:
  #   image: grafana/promtail:latest
  #   container_name: promtail
  #   volumes:
  #     - ./config/promtail.yaml:/etc/promtail/docker-config.yaml
  #     - /var/lib/docker/containers:/var/lib/docker/containers:ro
  #     - /var/run/docker.sock:/var/run/docker.sock
  #   command: -config.file=/etc/promtail/docker-config.yaml
  #   depends_on:
  #     - loki
  #   networks:
  #     - app

      schema: v11
      index:
        prefix: index_
        period: 24h

  shared_store: azure

When I start the container I can see the settings are loaded correctly but at the end there is error:
level=error ts=2023-10-02T14:49:22.70703502Z caller=log.go:106 msg="error running loki" err="mkdir : no such file or directory\nerror initialising module: compactor\ngithub.com/grafana/dskit/modules.(*Manager).initModule\n\t/src/loki/vendor/github.com/grafana/dskit/modules/modules.go:108\ngithub.com/grafana/dskit/modules.(*Manager).InitModuleServices\n\t/src/loki/vendor/github.com/grafana/dskit/modules/modules.go:78\ngithub.com/grafana/loki/pkg/loki.(*Loki).Run\n\t/src/loki/pkg/loki/loki.go:285\nmain.main\n\t/src/loki/cmd/loki/main.go:96\nruntime.main\n\t/usr/local/go/src/runtime/proc.go:255\nruntime.goexit\n\t/usr/local/go/src/runtime/asm_amd64.s:1581"

Then the conteiner shuts down automatically. Any help is going to be very much appriciated?
