Add MANIFEST.in, which includes:

justinmklam

#!/bin/bash

# This script takes a remote repository and merges it into
# the current one as a subdirectory

set -e

if [ -z "$1" ]
then
    echo "Usage:"

justinmklam

# Expose localhost at port 5000 to a random subdomain on serveo.net
ssh -R 80:localhost:5000 serveo.net

# Request a specific subdomain on serveo.net (ie. my-custom-app.serveo.net)
ssh -R my-custom-app:80:localhost:5000 serveo.net

# SSH session will close if no connections are made, so autossh will automatically reconnect and keep it persistent
sudo apt install autossh
autossh -M 0 -R my-custom-app:80:localhost:5000 serveo.net

The steps below provide a way to cross compile on your local development machine. Docker and QEMU to emulate the armhf/arm32v7 architecture.

Tested on:

• Ubuntu 18.04 LTS

Prerequisites

Install dependencies on your local development machine:

justinmklam

# Starts a detached screen and logs to a datestamped log file. '%' characters only need to be escaped if running this command via cron
screen -L -Logfile ~/my/log/path/$(date +\%Y-\%m-\%d_\%H-\%M-\%S).log -dm <command>

# Execute multiple commands in a detached screen session
screen -dm /bin/bash -c "command1 | command 2"
