This is quite a bit more than "a single Docker container" though, isn't it? This is networking, SSL cert, traffic routing, secret management and a whole CI pipleline.

Of course it's looking complicated "for a single container", but if you wanted to deploy your app in a traditional server setup, the graph would look the same, if not worse.

Exactly. This is more than just a single Docker container, this is all the architecture necessary to have a highly scalable, high availability setup where you can dial up the number of Docker containers as high as you want at the press of a button.

Not everyone needs all this, but most people who want scale and availability do need all this.
