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 ./glances.conf:/glances/conf/glances.conf -v /var/run/docker.sock:/var/run/docker.sock:ro --pid host -it docker.io/nicolargo/glances
|
|
|
|
Where ./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
|
|
|
|
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'
|
|
|
|

|
|
reverse-proxy:
|
|

whoami:

|
|

|
|
