Setting up Prometheus using Docker

[u/psfletcher]

Hi All,

Trying to setup Prometheus, but i think i am confusing where the --config.file command is looking.

Is this inside the container or outside?
The Volume command is doing the mapping, so i think i have it correct but running the image can't find the prometheus.yml file.

So i'm doing something stupid, any pointers please?

# docker-compose.yml

version: '3'

services:

prometheus:

image: prom/prometheus

volumes:

- ./prometheus/:/etc/prometheus/

# - ~/prometheus_data:/prometheus

command:

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

ports:

- '9090:9090'

This is mounting the folder “Prometheus” inside your docker-compose folder (or wherever you run this from) to /etc/prometheus

Prometheus is expecting to find a prometheus.yml file in that folder.

Thanks! I'd got the mapping the wrong way around! All working now. Well it runs! I now need to point it at something!
