Since the latest Docker Engine (version 29) requires Testcontainers 2.0.x, the plugin is no longer used, as it's not flexible enough and doesn't allow jOOQ Pro.

In many cases YAML makes the Spring configuration files much longer than properties files.
Additionally you cannot copy a single configuration line.

The idea of the internet was to have a decentralized network of computers.
But what we have today is a network with big players like Microsoft, Google, Amazon, and Cloudflare.
If one if these players fail, like Cloudflare currently, a large part of the internet fails.
We should go back.
