Setting up Glances with Docker Compose

When I first bought a VPS, I wanted to try installing all kinds of self-hostable software in it. After deploying tens of applications I then wanted a monitoring tool to see the resource consumption of all the containers. A simple Google search listed `Prometheus`, `Netdata`, and `Cockpit` but I wanted something more like the `htop` terminal app. Well, `Glances` was just perfect and it solved my problem as it was lightweight and I could see how my server performed in real-time. I wanted to self-host Prometheus, well I found it difficult to crack the setup as I was new to self-host as well as docker.

Glances can be deployed with Docker with a Docker command as follows:

docker run -d --restart="always" /
--container_name="glances" /
-p 61208-61209:61208-61209 /
-e GLANCES_OPT="-w" /
-v /var/run/docker.sock:/var/run/docker.sock:ro /
--pid host docker.io/nicolargo/glances

To deploy using Docker Compose:

version: "3"
services:
    glances:
        container_name: glances
        ports:
            - 61208-61209:61208-61209
        environment:
            - GLANCES_OPT=-w
        volumes:
            - /var/run/docker.sock:/var/run/docker.sock:ro
        pid: host
        image: nicolargo/glances:latest

This will open the ports 61208 and 61209.

If you are using proxy service like traefik then we could:

version: "3"
services:
    glances:
        container_name: glances
        environment:
            - GLANCES_OPT=-w
        volumes:
            - /var/run/docker.sock:/var/run/docker.sock:ro
        pid: host
        image: nicolargo/glances:latest
        networks:
            - traefik-network
        labels:
            - traefik.enable=true
            - traefik.http.routers.glances.rule=Host(`glance.example.com`)
            - traefik.http.routers.glances.entrypoints=https
            - traefik.http.services.glances.loadbalancer.server.port=61208
            - traefik.http.routers.glances.tls=true


networks:
  traefik-network:
    external: true
