As you know, deploying a basic viable app configuration in Kubernetes is a breeze. On the other hand, you will inevitably encounter many obstacles and pitfalls trying to make your application as available and fault-tolerant as possible.

Also, we will not lock into specific CD solutions, and we will omit the issues of templating Kubernetes manifests and generating them. We will only look at general rules about how Kubernetes manifests might look (that is, when they are fully ready to use).
