SIG API Machinery Deep Dive – Stefan Schimanski, Red Hat (Intermediate Skill Level)
SIG API Machinery is responsible for all generic API topics in Kubernetes, i.e. for the generic API server implementation, API CRUD semantics, discovery the admission control mechanism, conversion, defaulting, persistence with etcd, general controllers like garbage collection, Go client libraries, code generation and extension points like CustomResourceDefinitions, aggregation admission.
This session will have two parts:
A deep dive into a selection for API Machinery topics, probably: defining API types in Golang, groups+versions+kinds+resources, tags, code-generation, schemes, different variants of codecs – and how to use all this with CustomResourceDefinitions and a custom client-go client.
time for general discussion and opportunity for API machinery questions
This session is targetted especially at:
People using the Kubernetes APIs with client-go and wanting to understand what is going on behind the scenes
People extending Kubernetes with APIs using aggregated API servers or CustomResourceDefinitions

The

The

we
have
is

to

the

to

so
to

as
well
as

because
the
