Ansible Role: RPI-Monitor for Raspberry Pi/s

This Ansible role aims at installing and configuring RPi Monitor utilising as development platform a Raspberry Pi 3B and 4B.

RPi-Monitor allows serving real-time monitoring information (Uptime, CPU load, Temperature, Memory, Disk size, etc...) from your embedded raspberry Pi devices via HTTP in a non-standard port.

Further documentation here

Data is served over plain-text (HTTP only) and there might be other unkown Perl exploits given the age of this project. Thus I would not recommend openning ports widely to access data through the Internet without properly configuring a VPN tunnel, for example.

Requirements

Ansible 2.7+
Linux Distribution:
- Raspian Debian Family

A reachable set of Raspberry Pi/s bootstrapped over SSH already (ready to run Ansible modules configured with password-less sudo user, e.g. pi user comes preconfigured this way by default)

Role Variables

The following variables could be setup externally and are self-explanatory

[defaults](defaults/main.yml)
rpimonitor_user: rpimonitor
rpimonitor_group: rpimonitor
rpimonitor_port: 8888
rpimonitor_ip_addr: 0.0.0.0

Dependencies

There are no other dependencies necessary to run this playbook

Example Playbook

A simplistic approach to this role.

---
# default playbook.yml
- hosts: raspberry_pi
  roles:
      - kitos9112.rpimonitor

# default inventory hosts file
$> cat hosts
#(...)
[raspberry_pi]
  rpi_master-01 ansible_host=192.168.1.101
  rpi_master-02 ansible_host=192.168.1.102
  rpi-slaves-0[1-5] ansible_host=192.168.1.11[0-5]
#(...)

CLI command to fire off:

$> ansible-playbook -i hosts playbook.yml -l raspberry_pi
