Windows Setup

https://www.raspberrypi.com/documentation/computers/compute-module.html

https://jamesachambers.com/full-compute-module-4-raspberry-pi-setup-imaging-guide/

Windows Installer

For those who just want to enable the Compute Module eMMC as a mass storage device under Windows, the stand-alone installer is the recommended option. This installer has been tested on Windows 10 32-bit and 64-bit, and Windows XP 32-bit.

Please ensure you are not writing to any USB devices whilst the installer is running.

  1. Download and run the https://github.com/raspberrypi/usbboot/raw/master/win32/rpiboot_setup.exe to install the drivers and boot tool.
  2. Plug your host PC USB into the USB SLAVE port, making sure you have setup the board as described above.
  3. Apply power to the board; Windows should now find the hardware and install the driver.
  4. Once the driver installation is complete, run the RPiBoot.exe tool that was previously installed.
  5. After a few seconds, the Compute Module eMMC will pop up under Windows as a disk (USB mass storage device).

Setup

Install image to Compute using imager software. The 64 Bit Lite version should be used.

The following commands can be executed manually, or can be saved into an 'sh' file (e.g. setup.sh) and then run using bash setup.sh 

sudo apt-get update
sudo apt-get upgrade
bash <(curl -sL https://raw.githubusercontent.com/node-red/linux-installers/master/deb/update-nodejs-and-nodered)
sudo systemctl enable nodered.service

sudo apt-get -y install mosquitto

sudo git clone https://github.com/rscada/libmbus.git
cd libmbus
sudo sh clean.sh

Mediawiki

In Portainer create and deploy a Stack called wiki, pasting the following into the editor.


See https://github.com/heatweb/plumbing-controller/blob/main/docker/docker-compose-wiki.yaml 

# MediaWiki with MySQL
# Access via "http://localhost:8080"
#   (or "http://$(docker-machine ip):8080" if using docker-machine)
version: '3'
services:
  mediawiki:
    image: arm64v8/mediawiki
    restart: always
    networks:
      - wiki-net
    ports:
      - 8080:80
    volumes:
      - /var/www/html/
# After initial setup, download LocalSettings.php to the same directory as
# this yaml and uncomment the following line and use compose to restart
# the mediawiki service
# - ./LocalSettings.php:/var/www/html/LocalSettings.php
  database:
    image: arm64v8/mysql:latest
    restart: always
    networks:
      - wiki-net
    environment:
      MYSQL_DATABASE: wiki_db
      MYSQL_ROOT_PASSWORD: root
      MYSQL_USER: wikimedia
      MYSQL_PASSWORD: wikimedia
    volumes:
      - /var/lib/mysql
networks:
  wiki-net:
    driver: bridge

Note: You may need to add the running containers to the mqtt docker network in Portainer.
