New Docker Install with persistent storage, Permission problem

Grafana Configuration

Option 1, docker volumes

With persistent storage you have a few different options. You can create a docker volume and in vanilla docker that will work with the file permissions for the Grafana docker container (id = 472, group = 472).

version: '3'

services:
  grafana:
    image: grafana/grafana:5.2.4
    volumes:
      - grafana-storage:/var/lib/grafana
    ports:
      - 3000:3000

volumes:
  grafana-storage:

Option 2, using a folder on your local filesystem

When using a local folder you need to do a little bit of extra work to make it so that the docker container can read the contents of the folder as well as write to it. In the example below we will modify the user that Grafana runs as within the container so that it runs as the same user id as you do in your local file system, this will guarantee that it has access if you do.

  1. mkdir gfdata

  2. id -u (this will give you your user id, which you will enter into the docker-compose file. In my case it is 1001, replace 1001 in the docker-compose file with your id)

  3. docker-compose.yml

version: '3'

services:
  grafana:
    image: grafana/grafana:5.2.4
    user: "1001"
    volumes:
      - ./gfdata:/var/lib/grafana
    ports:
      - 3000:3000

I hope this helps clearing up some of the confusion.
