Moby's Pulse

A little prometheus exporter to get the restarts of containers, with multiple attributes to get specific container information.

Installation

The easiest way to install Moby's Pulse is to use the provided Docker image. You can pull the image from the GitHub Container Registry:

docker pull ghcr.io/gowizzard/mobyspulse:latest

Usage

To start the exporter, you can use the following docker compose file:

services:
    mobyspulse:
        container_name: mobyspulse
        environment:
            - BASIC_AUTH_USERNAME=moby
            - BASIC_AUTH_PASSWORD=pulse
        volumes:
            - /var/run/docker.sock:/var/run/docker.sock
        ports:
            - "3000:3000"
