Docker

Glances can be installed through Docker, allowing you to run it without installing all the python dependencies directly on your system. Once you have [docker installed](https://docs.docker.com/install/), you can

Get the Glances container:

docker pull nicolargo/glances

Run the container in console mode:

docker run --rm -v /var/run/docker.sock:/var/run/docker.sock:ro --pid host --network host -it docker.io/nicolargo/glances

Additionally, if you want to use your own glances.conf file, you can create your own Dockerfile:

FROM nicolargo/glances
COPY glances.conf /glances/conf/glances.conf
CMD python -m glances -C /glances/conf/glances.conf $GLANCES_OPT

Alternatively, you can specify something along the same lines with docker run options:

docker run -v `pwd`/glances.conf:/glances/conf/glances.conf -v /var/run/docker.sock:/var/run/docker.sock:ro --pid host -it docker.io/nicolargo/glances

Where `pwd`/glances.conf is a local directory containing your glances.conf file.

Run the container in Web server mode (notice the GLANCES_OPT environment variable setting parameters for the glances startup command):

docker run -d --restart="always" -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

Note: if you want to see the network interface stats within the container, add –net=host –privileged

You can also include Glances container in you own docker-compose.yml. Here’s a realistic example including a “traefik” reverse proxy serving an “whoami” app container plus a Glances container, providing a simple and efficient monitoring webui.

version: '3'

services:
  reverse-proxy:
    image: traefik:alpine
    command: --api --docker
    ports:
      - "80:80"
      - "8080:8080"
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock

  whoami:
    image: emilevauge/whoami
    labels:
      - "traefik.frontend.rule=Host:whoami.docker.localhost"

  monitoring:
    image: nicolargo/glances:latest-alpine
    restart: always
    pid: host
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
    environment:
      - "GLANCES_OPT=-w"
    labels:
      - "traefik.port=61208"
      - "traefik.frontend.rule=Host:glances.docker.localhost"
