Apache Ignite First Steps

Apache Ignite is a horizontally scalable fault-tolerant distributed in-memory computing platform.

As of now, there is a Hello World application to get started on this platform. But the documentation requires us to fill in a few important details by ourselves; otherwise the application can't be run successfully.

Here is a complete set of steps to run this application (self contained with the code).

Prerequisites

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.
