Before we dig into this rather lengthy tutorial, let me apologize. This is part three (see parts one and two) and it’s taken me several months to finally write it, for two reasons: First, as the founder of the company, my presence and attention was needed elsewhere, and second, I wanted our website to run on this set up for a while, so that I was sure what I’ll write is going to have good, reliable and performant outcome. Also, since we’ll be using Google Cloud to deploy this solution, be warned that we will be spinning up a couple of relatively small virtual servers, which does come with a cost of a few dollars (for the duration of you running these servers to follow the tutorial), so make sure that you delete them all after we’re done. The good news is that if you never used Google Cloud before, you’re given a $300 bonus by Google to try it out!
Let’s get started!
Kubernetes, in short, is a container orchestration tool. That means it does all the heavy lifting to make sure our containers are running properly, destroys the unneeded ones or spins up new ones, makes sure that traffic routing is correct between them and a number of other, useful things, most of which need to be done manually
