⚠️IMPORTANT NOTICE: Images undergcr.io/kubebuilder/ Will Be Unavailable Soon

If your project usesgcr.io/kubebuilder/kube-rbac-proxy it will be affected.Your project may fail to work if the image cannot be pulled.You must move as soon as possible, sometime from early 2025, the GCR will go away.

The usage of the projectkube-rbac-proxy was discontinued from Kubebuilder and Operator-SDK.It was replaced for similar protection usingauthn/authz via Controller-Runtime's featureWithAuthenticationAndAuthorization.

For more information and guidance see the discussionkubernetes-sigs/kubebuilder#3907

Docs can be found on theOperator SDK website.

This project is a component of theOperator Framework, anopen source toolkit to manage Kubernetes native applications, calledOperators, in an effective, automated, and scalable way. Read more intheintroduction blog post.

Operators make it easy to manage complex statefulapplications on top of Kubernetes. However writing an Operator today canbe difficult because of challenges such as using low level APIs, writingboilerplate, and a lack of modularity which leads to duplication.

The Operator SDK is a framework that uses thecontroller-runtime library to make writingoperators 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 thedeveloper guide.A Go Operator project's Go version can be found in itsgo.mod file.

Supported Kubernetes versions for your Operator project or relevant binary can be determinedby following thiscompatibility guide.

The set of supported platforms for all binaries and images can be found inthese tables.

• Operator framework community
• Communication channels
• Project meetings
