Glances Docker ignores configuration file

[auanasgheps]

Describe the bug
I am using a simple configuration file for my Docker instance of Glances:

[network]    
hide=docker.,lo,br,veth.*

I also tried other simple commands, there's no change.

It used to work perfectly, and Glances log would say: Read configuration file '/etc/glances.conf'
This is not happening anymore. I think I was using by mistake an old image, and since I upgraded it, the config file is simply being ignored. There's no mention or error in Glances logs.

This is my docker-compose

version: "2"

services:
   monitoring:
    image: nicolargo/glances:latest
    container_name: glances
    privileged: true
    restart: unless-stopped
    pid: host
    volumes:
      - /srv/nvme/docker-apps/glances/logs:/tmp
      - /srv/nvme/docker-apps/glances/conf/glances.conf:/etc/glances.conf
      - /srv/nvme:/mnt/nvme:ro
      - /etc/os-release:/etc/os-release:ro
    environment:
      - "GLANCES_OPT=-w"
      - "TZ=Europe/Rome"
    network_mode: "host"

To Reproduce
Steps to reproduce the behavior:

1. Create a config file for Glances
2. Run Glances with docker using the stack above
3. Config file is ignored

Expected behavior
Config file should be applied.

Additional context
Used to work fine with an old (can't remember) image

[nicolargo]

Try to force the /etc/glances.conf file in the GLANCES_OPT variable:

services:
   monitoring:
    image: nicolargo/glances:latest
    container_name: glances
    privileged: true
    restart: unless-stopped
    pid: host
    volumes:
      - /srv/nvme/docker-apps/glances/logs:/tmp
      - /srv/nvme/docker-apps/glances/conf/glances.conf:/etc/glances.conf
      - /srv/nvme:/mnt/nvme:ro
      - /etc/os-release:/etc/os-release:ro
    environment:
      - "GLANCES_OPT=-w -C /etc/glances.conf"
      - "TZ=Europe/Rome"
    network_mode: "host"

It works, thank you! I think it's time to update the documentation, I will try to do a PR

Glances config file inside the container is at /etc/glances/glances.conf, not /etc/glances.conf if you set that in your volume config, you don't need to force the config file.
