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"

How to protect your Dockerized server (or Web server) with a login/password ?
|
|
------------------------------------------------------------------
|
|
|
|
Below are two methods for setting up a login/password to protect Glances running inside a Docker container.
|
|
|
|
Option 1
|
|
^^^^^^^^
|
|
|
|
You can enter the running container by entering this command (replacing ``glances_docker`` with the name of your container):
|
|
|
|
.. code-block:: console
|
|
|
|
docker exec -it glances_docker sh
|
|
|
|
and generate the password file (the default login is ``glances``, add the ``--username`` flag if you would like to change it):
|
|
|
|
.. code-block:: console
|
|
|
|
glances -s --password
|
|
|
|
which will prompt you to answer the following questions:
|
|
|
|
.. code-block:: console
|
|
Define the Glances server password (glances username):
|
|
Password (confirm):
|
|
Do you want to save the password? [Yes/No]: Yes
|
|
|
|
after which you will need to kill the process by entering ``CTRL+C`` (potentially twice), before leaving the container:
|
|
|
|
.. code-block:: console
|
|
exit
|
|
|
|
You will then need to copy the password file to your host machine:
|
|
|
|
.. code-block:: console
|
|
docker cp glances_docker:/root/.config/glances/glances.pwd ./secrets/glances_password
|
|
|
|
and make it visible to your container by adding it to ``docker-compose.yml`` as a ``secret``:
|
|
|
|
.. code-block:: yaml
|
|
version: '3'
|
|
|
|
services:
|
|
glances:
|
|
image: nicolargo/glances:latest
|
|
restart: always
|
|
environment:
|
|
- GLANCES_OPT="-w --password"
|
|
volumes:
|
|
- /var/run/docker.sock:/var/run/docker.sock:ro
|
|
pid: host
|
|
secrets:
|
|
- source: glances_password
|
|
target: /root/.config/glances/glances.pwd
|
|
|
|
secrets:
|
|
glances_password:
|
|
file: ./secrets/glances_password
|
|
|
|
Option 2
|
|
^^^^^^^^
|
|
|
|
You can add a ``[passwords]`` block to the Glances configuration file as mentioned elsewhere in the documentation:
|
|
|
|
.. code-block:: ini
|
|
|
|
[passwords]
|
|
# Define the passwords list
|
|
# Syntax: host=password
|
|
# Where: host is the hostname
|
|
# password is the clear password
|
|
# Additionally (and optionally) a default password could be defined
|
|
localhost=mylocalhostpassword
|
|
default=mydefaultpassword
|
