Re: [prometheus-users] Error: Opening storage failed open DB in prometheus/ .... permission denied

[Simon Pasquier]

The prom/prometheus container runs as "nobody" so you need to make sure that the "nobody" user has write permissions on the host's directory ($PWD/data/prometheus/data in your case).

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 this?

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:
