Raspberry Pi on Internet via reverse SSH tunnel

HackerNews discussed this with many alternative solutions: https://news.ycombinator.com/item?id=24893615

I already have my own domain name: mydomain.com. I wanted to be able to run some webapps on my Raspberry Pi 4B running perpetually at home in headless mode (just needs 5W power and wireless internet). I wanted to be able to access these apps from public Internet. Dynamic DNS wasn't an option because my ISP blocks all incoming traffic. ngrok would work but the free plan is too restrictive.

I bought a cheap 2GB RAM, 20GB disk VM + a 25GB volume on Hetzner for about 4 EUR/month. Hetzner gave me a static IP for it. I haven't purchased a floating IP yet.

Converting an arbitrary list of key-value pairs from the command-line into a Python dictionary

Problem

You want to create a series of key-value pairs from the command line, using the argparse library, e.g.:

command par1 par2 --set foo=hello bar="hello world" baz=5

This is typically useful when you want to clearly distinguish":

1. Ordinary arguments for the command-line utility itself (output, input, format, etc.) from
2. A set of key-value pairs you want to pass to the python application. This is especially valid when you do not want that set of values to be predetermined, as this can save a lot of code.

Given a dictionary, transform it to a string. Then byte encode that string. Then base64 encode it and since this will go
on a url, use the urlsafe version. Then decode the byte string so that it can be else where.

data = base64.urlsafe_b64encode(json.dumps({'a': 123}).encode()).decode()

# And the decode is just as simple...

Requirements

Minikube requires that VT-x/AMD-v virtualization is enabled in BIOS. To check that this is enabled on OSX / macOS run:

sysctl -a | grep machdep.cpu.features | grep VMX

If there's output, you're good!
