Kubernetes Extensibility - 1/2 Day Hands On Workshop

Kubernetes is highly configurable and extensible. As a software developer, once you understand how something works the next thing you naturally ask is how to extend it to meet your needs. Kubernetes is declarative by its nature which allows you to configure the state of a cluster to meet your needs. However, with all of the Kubernetes resources, it can't do everything. Fortunately, Kubernetes has a build-in architectural feature of extensibility.

In this workshop, we will build on your existing knowledge of containers and Kubernetes and add techniques for extending Kubernetes to help to meet your real world needs.

We will cover many topics extensibility, such as:

  • Kubernetes API
  • Custom Resource Definitions
  • Controllers
  • Security and Roles
  • Kubectl plugins
  • Operator Pattern
  • Public Operators
  • Choices for developing your own Operator
  • Hands on labs

About Jonathan Johnson

Jonathan Johnson is an independent software architect with a concentration on helping others unpack the riches in the cloud native and Kubernetes ecosystems.

For 30 years Jonathan has been designing useful software to move businesses forward. His career began creating laboratory instrument software and throughout the years, his focus has been moving with industry advances benefitting from Moore’s Law. He was enticed by the advent of object-oriented design and applied it to financial software. As banking moved to the internet, enterprise applications took off and Java exploded onto the scene. Since then, he has inhabited that ecosystem. After a few years, he returned to laboratory software and leveraged Java-based state machines and enterprise services to manage the terabytes of data flowing out of DNA sequencing instruments. As a hands-on architect, he applied the advantages of microservices, containers, and Kubernetes with a laboratory management platform.

Today he enjoys sharing his experience with peers. He provides perspective on ways to modernize application architectures while adhering to the fundamentals of modularity - high cohesion and low coupling.microservices, containers, and Kubernetes to their laboratory management platform.
