Go to the directory with the image you want to work with. Run a Docker container with that directory mounted:

docker run -it --privileged -v /dev:/dev -v (pwd):/tmp --workdir /tmp ubuntu bash

(replace (pwd) with "$PWD" if using bash instead of fish)

See this thread for an explanation of why --privileged and -v /dev:/dev are required. The need for the latter can be avoided with this alrternative workaround.

In the container, assuming that $IMAGE_FILE is the name of your image file:

sudo apt install npm
sudo npm install -g npm@latest
sudo npm install bower -g

git clone https://github.com/sabhiram/raspberry-wifi-conf.git
cd raspberry-wifi-conf
npm update
bower install
sudo npm run-script provision

sudo apt update && sudo apt upgrade

sudo apt install golang
sudo apt-get install libmnl-dev libelf-dev build-essential pkg-config

cd wireguard-go/
git checkout 0.0.20181001 # Get the desired release tag from `git tag`
make
sudo make install

Get PDF export of Grafana dashboard

Note

As currently described, this approach does not work. The reason for that is that creating a snapshot via the API does not actually populate any data, as described in e.g. https://community.grafana.com/t/snapshot-using-http-api-does-nothing/. An alternative approach which does work described in https://gist.github.com/svet-b/1ad0656cd3ce0e1a633e16eb20f66425.

Prerequisites

Packages:

• The jq JSON processing command line tool, which is available for most distributions (https://stedolan.github.io/jq/, sudo apt install jq)
• NodeJS, and the puppeteer package (npm install puppeteer), which is used to run headless Chrome

It's possible to do search-and-replace on Grafana dashboard definitions by directly manipulating the SQLite database. The key steps after logging into the server are as follows:

cd /var/lib/grafana
# Make backup copy; preserve old backup copies
sudo cp --backup=numbered grafana.db grafana.db.bak

# Stop Grafana
sudo systemctl stop grafana-server

Create Raspbian SD card with image from https://www.raspberrypi.org/downloads/raspbian/

Create file named ssh in boot partition, so that ssh is enabled on boot.

Log into Raspberry Pi (user pi, password raspberry).

Set strong password on pi user. (passwd) (optional) Copy SSH key

ssh-copy-id -i id_ed25519_ammpedge pi@[raspberry_IP]

# Ensure that package dependencies are met (specifically python3, libsnmp-dev, and python3-netifaces)

# Create user under which software will be run.
# Enter user directory. In this example this is /opt/datalog

# Pull the codebade
git clone https://github.com/ammpio/ammp-edge.git

# Install python package
cd ammp-edge

This works on the v3 firmware of the Moxa UC-8100(-LX)
