Permission error, binding prometheus data to host

[julia...@covus.de]

Hey @ all,

I searched the internet for 2 hours for a solution for this error but I don't find anything that helped.

On my Mac (local machine) it runs perfect, but not on the Ubuntu 16.04 server.

Any suggestions about how I can bind the volume to my host?

This is my docker-compose.yml

    prometheus:

      build: ./prometheus

      volumes:

        - $PWD/data/prometheus/:/prometheus/

      command:

        - '--config.file=/etc/prometheus/prometheus.yml'

        - '--storage.tsdb.path=/prometheus/'

      ports:

        - 9090:9090

This my dockerfile:

FROM prom/prometheus:latest

COPY ./alert.rules    /etc/prometheus/alert.rules

COPY ./prometheus.yml /etc/prometheus/prometheus.yml

this is my error:

Solved this Problem:

created a group "nobody"

:~/mal/data$ sudo addgroup nobody
Done.
:~/mal/data$ sudo usermod -aG nobody nobody
:~/mal/data$ sudo chown nobody:nobody prometheus/
:~/mal/data$ ll
total 20
drwxr-xr-x 5 worker worker  4096 Feb 28 09:56 ./
drwxrwxr-x 7 worker worker  4096 Feb 28 10:21 ../
drwxr-xr-x 3 nobody nobody  4096 Feb 28 10:11 prometheus/

And now this works ... 

@Prometheus team ... maybe add this to your docker README.md page!
