Overview

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

Dependency and platform support

Go version

Release binaries will be built with the Go compiler version specified in the Operator SDK's [prerequisites section][doc-readme-prereqs].

Kubernetes versions

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].

Platforms

The following matrix defines which architectures are supported for GNU Linux:

amd64 arm64 ppc64le s390x
operator-sdk
ansible-operator
helm-operator
scorecard-test image
scorecard-test-kuttl image -

The following matrix defines which architectures are supported for MacOS Darwin:

amd64
operator-sdk
ansible-operator
helm-operator

Support for the Windows platform is not on the roadmap at this time.
