Ask HN: How to learn more about distributed systems

Hi,

Like most people here, I've been witnessing a fair amount of buzz/hype around technologies like Docker, Kubernetes, etc.. However, while I understand the broad-strokes outline of these technologies, as well as the motivations behind them, I am at a loss as to how they are actually supposed to be used.

With all the distributed systems/containerization/whatever systems out there, how do you figure out which parts to use in which configuration? Are there any good tutorials or books out there that cover the sweet spot between the generally too-specific Docker-related blog post and more academic distributed systems treatises?

In slightly different words, how would you recommend I bring myself up to speed on these technologies?
