Extending the Kubernetes API
Kubernetes is an extremely flexible platform. It was designed from the get-go for extensibility, and as it evolved, more parts of Kubernetes were opened up, exposed through robust interfaces, and they can be replaced by alternative implementations. I venture to say that the exponential adoption of Kubernetes across the board by start - ups, large companies, infrastructure providers, and cloud providers is a direct result of Kubernetes providing a lot of capabilities out of the box, but also allowing easy integration with other actors. In this section, we will cover many of the available extensions points, such as the following:
- User-defined types (custom resources)
- API access extensions
- Infrastructure extensions
- Operators
- Scheduler extensions
Let's understand the various ways you can extend Kubernetes.
