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:
.. code-block:: console
docker pull nicolargo/glances
Run the container in *console mode*:
.. code-block:: console
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:
.. code-block:: console
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:
.. code-block:: console
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):
.. code-block:: console
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.
.. code-block:: console
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"
