KUBERNETES OPERATORS - JASON DOBIES JOSHUA WOOD...

Operators are a way of packaging  deploying  and managing Kubernetes applications. A Kubernetes
application doesn't just run on Kubernetes  it's composed and managed in Kubernetes terms.
Operators add application-specific operational knowledge to a Kubernetes cluster  making it
easier to automate complex  stateful applications and to augment the platform. Operators can
coordinate application upgrades seamlessly  react to failures automatically  and streamline
repetitive maintenance like backups. Think of Operators as site reliability engineers in
software. They work by extending the Kubernetes control plane and API  helping systems
integrators  cluster administrators  and application developers reliably deploy and manage key
services and components. Using real-world examples  authors Jason Dobies and Joshua Wood
demonstrate how to use Operators today and how to create Operators for your applications with
the Operator Framework and SDK. Learn how to establish a Kubernetes cluster and deploy an
Operator Examine a range of Operators from usage to implementation Explore the three pillars of
the Operator Framework: the Operator SDK  the Operator Lifecycle Manager  and Operator Metering
Build Operators from the ground up using the Operator SDK Build  package  and run an Operator
in development  testing  and production phases Learn how to distribute your Operator for
installation on Kubernetes clusters
