Look at what Kubernetes can do... it's beyond even an operating system, it's like if systemd controlled a whole datacenter. It handles everything too--networking, storage, processes, jobs, etc. Of course that's going to be a complex thing with a large surface area. The fact you can just curl into the API server with a consistent and discoverable (all OpenAPI) API is pretty darn amazing.

- wutbrodo 6y agoThe claim was that the _API_ is simple relative to the system's capabilities, including being discoverable and standardized (w openapi). If passenger jets had a comparable API you could use to ramp up to the level of competence that you can on k8s, that would be pretty amazing.
- matt-attack 6y agoWhat is a discoverable API?
- aliswe 6y agoI guess this means that you're able to learn how the API works by using the API to download metadata. In fact, one can generate a complete API client by pointing a script to a running kubernetes instance, which will generate all code for interacting with exactly that version. And the resulting client is huuuge. (That generation thingy is for some .net clients)
- qbasic_forever 6y agoThere's a full open API schema served by the API server. Tools can read it and build specific interfaces or validate requests before even sending them. And in general k8s is really just a big database of objects. Once you learn the core objects like pod, deployment, service, etc. it becomes very natural to interact with anything else--just find what object it is and interact with its attributes.
