glances.conf config file is not respected in web (-w) server mode

[Tomipapa]

I am starting my glances container with this command:

docker run -d --restart="always" \
		-p 61208-61209:61208-61209 \
                -e GLANCES_OPT="-w" \
		-v $(pwd)/glances.conf:/etc/glances/glances.conf \
		-v /var/run/docker.sock:/var/run/docker.sock:ro \
		--pid host \
		--hostname "glances_$(hostname)" \
		--name glances \
		docker.io/nicolargo/glances

However, the container doesn't use the configuration options contained in the glances.conf fiile:

~/containers/glances$ cat $(pwd)/glances.conf
[global]
# Does Glances should check if a newer version is available on PyPI ?
check_update=false

[outputs]
# Theme name for the Curses interface: black or white
curse_theme=white

[cpu]
disable=true

Hi @Tomipapa

Try with the -C option:

docker run -d --restart="always" \
		-p 61208-61209:61208-61209 \
		-e GLANCES_OPT="-w -C /etc/glances/glances.conf" \
		-v $(pwd)/glances.conf:/etc/glances/glances.conf \
		-v /var/run/docker.sock:/var/run/docker.sock:ro \
		--pid host \
		--hostname "glances_$(hostname)" \
		--name glances \
		docker.io/nicolargo/glances

Hi @nicolargo,

Thanks for your suggestion...

I have started the container with -e GLANCES_OPT="-w -C /etc/glances/glances.conf", but as it appears the -C parameter doesn't make any difference, even though the host-mapping configuration works properly:

~/containers/glances$ docker exec -ti glances sh
/app # cat /etc/glances/glances.conf 
[global]
# Does Glances should check if a newer version is available on PyPI ?
check_update=false

[outputs]
# Theme name for the Curses interface: black or white
curse_theme=white

[cpu]
disable=true

[system]
system_info_msg=TEST

What's the result on the Web UI (please copy/paste a screenshot)/

[nicolargo]

It works on my side with the same glances.conf file:

docker run --restart="always" -p 61208-61209:61208-61209 -e TZ="${TZ}" -e GLANCES_OPT="-w -C /glances.conf" -v /tmp/glances.conf:/glances.conf:ro -v /var/run/docker.sock:/var/run/docker.sock:ro -v /run/user/1000/podman/podman.sock:/run/user/1000/podman/podman.sock:ro --pid host nicolargo/glances:latest-full

@nicolargo,

Thanks for your time and testing...

Finally, it works for me too. Actually, it was not clear that the glances.conf file is not processed on-the-fly, and it is necessary to recreate the container => restart glances. It would be a nice new feature to make glances.conf dynamic...

Another thing is that I do not happen to see any changes by modifying these configuration options:

[outputs]
# Theme name for the Curses interface: black or white
curse_theme=white

[cpu]
disable=false

Could you please check these on your side as well?

[nicolargo]

The white theme is only available on the Curses (consoler) UI not the webui. There is already an enhancement request regarding this feature.

Thanks, for the update...
