This project is a component of the Operator Framework, an open source toolkit to manage Kubernetes native applications, called Operators, in an effective, automated, and scalable way. Read more in the introduction blog post.
Operators make it easy to manage complex stateful applications on top of Kubernetes. However writing an operator today can be difficult because of challenges such as using low level APIs, writing boilerplate, and a lack of modularity which leads to duplication.
The Operator SDK is a framework that uses the controller-runtime library to make writing operators easier by providing:
- High level APIs and abstractions to write the operational logic more intuitively
- Tools for scaffolding and code generation to bootstrap a new project fast
- Extensions to cover common operator use cases
Release binaries will be built with the Go compiler version specified in the Operator SDK's [prerequisites section][doc-readme-prereqs].
As the Operator SDK interacts directly with the Kubernetes API, certain API features are assumed to exist in the target cluster. The currently supported Kubernetes version will always be listed in the SDK [prerequisites section][doc-readme-prereqs].
