Even with all of the standard Kubernetes resources, it can’t do everything. Fortunately, 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 opens its architecture that you can extend to meet your needs.
The Operator pattern has emerged from this extensibility goal. Increasingly, solutions on Kubernetes follow the Operator pattern. You’ll explore some common open-source solutions, and few frameworks commonly used to create your own Operators.
Serverless on Kubernetes is a cloud-agnostic way to rapidly serve applications. Building on your understanding of Operators, we will investigate a few serverless solutions that leverage the pattern. This is an ideal topic to give you a deeper understanding of how Kubernetes works.
Distributed application architectures are hard. The complexity in building containers and designing microservices to work together across a network can be overwhelming. To successfully manage limitations on resources, failing networks, defective software, and fluctuating traffic, you need an orchestrator.
Kubernetes is designed to handle these complexities, so you don’t have to. Essentially a distributed operating system for your data center, you give Kubernetes containers, and it makes sure that they remain available and responsive. As such, Kubernetes is quickly becoming the preferred way to serve distributed, scalable, and resilient applications.
Jonathan Johnson walks you through Kubernetes building blocks to demonstrate how the tool actually works. You may already understand containers—the tricky part is getting a whole set of containers and services to consistently work together and run reliably. In this three-part series, you’ll get comfortable designing, deploying, managing, and updating a coordinated set of applications running on Kubernetes.
Although you can attend any of the three courses individually, we recommend pursuing the entire series, in this order: Week 1: Getting Started with Kubernetes—Introduction, terminology, architecture, and first apps Week 2: Containers and Microservices—Packaging and running apps Week 3: Applications and Patterns—Patterns for apps leveraging Kubernetes
