How to create a custom app for glances?

[Janus Ng]

Hi all.

First a little background about me. Albeit I used FreeNAS 9 to TrueNAS Core 12, I am new to TrueNAS SCALE. I have stopped messing with TrueNAS since my HPE MicroServer Gen 8 died 3 years ago. I have no experience on Kubernetes either. I deploy containers most through docker compose.

I have recently assembled a used Supermicro machine with 12 bays for running TrueNAS SCALE. I have install TrueNAS SCALE 2023.10.0.1 on it.

I would like to install a simple container, glances on it. Here is the compose.yaml I used on a ubuntu 23.10.

Here is the content of my compose.yaml running on a ubuntu 2023.10:

Code:

---
version: "3"
services:
  glances:
    image: nicolargo/glances:latest-full
    container_name: glances
    deploy:
      resources:
        limits:
          memory: 1G
    pid: host
    network_mode: host
    environment:
      - "GLANCES_OPT=-w --password -u ha"
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock:ro
      - ./etc/glances.conf:/etc/glances.conf:ro
    secrets:
      - source: glances_password
        target: /root/.config/glances/ha.pwd
    restart: unless-stopped


secrets:
  glances_password:
    file: ./secrets/ha.pwd

I am having difficulty to get it work with the custom app module on TrueNAS SCALE. Particularly, how to pass the pid and volume /var/run/docker.sock onto the container. I would be delighted if there is a replacement for secrets but I am fine without it.

So far, I cannot even get it working on port 61208.

Any help would be greatly appreciated.
