AWS Controllers for Kubernetes (ACK)

AWS Controllers for Kubernetes (ACK) lets you define and use AWS service resources directly from Kubernetes. With ACK, you can take advantage of AWS managed services for your Kubernetes applications without needing to define resources outside of the cluster or run services that provide supporting capabilities like databases or message queues within the cluster.

ACK is an open source project built with ❤️ by AWS. The project is composed of many source code repositories containing a common runtime, a code generator, common testing tools and Kubernetes custom controllers for individual AWS service APIs.

IMPORTANT Please be sure to read our documentation about release versioning and maintenance phases and note that ACK service controllers in the Preview maintenance phase are not recommended for production use. Use of ACK controllers in Preview maintenance phase is subject to the terms and conditions contained in the AWS Service Terms, particularly the Beta Service Participation Service Terms, and apply to any service controllers in a Preview maintenance phase.


Kubernetes applications often require a number of supporting resources like databases, message queues, and object stores. AWS provides a set of managed services that you can use to provide these resources for your apps, but provisioning and integrating them with Kubernetes was complex and time consuming. ACK lets you define and consume AWS services and resources directly from a Kubernetes cluster. It gives you a unified way to manage your application and its dependencies.

ACK is a collection of Kubernetes custom resource definitions (CRDs) and custom controllers working together to extend the Kubernetes API and manage AWS resources on your behalf.

Getting Started

Please see the list of ACK service controllers currently in one of our project stages.

You can install any of the controllers in the RELEASED project stage using Helm (recommended) or manually using the raw Kubernetes manifests contained in the individual ACK service controller's source repository.

Once installed, Kubernetes users may apply a custom resource (CR) corresponding to one of the resources exposed by the ACK service controller for the service.

To view the list of custom resources and each CR's schema, visit our reference documentation.
