ACK service controller for Amazon Elastic Kubernetes Service (EKS)

This repository contains source code for the AWS Controllers for Kubernetes (ACK) service controller for Amazon EKS.

Please log issues and feedback on the main AWS Controllers for Kubernetes Github project.

Getting started

To install the eks-controller on your cluster, follow the the installation instructions.

Currently, the eks-controller is GA and supports the following resources:

• Cluster
• Nodegroup
• FargateProfile
• Addon
• PodIdentityAssociation
• AccessEntry

A detailed list of the resources supported specifications can be found in the references section.

Annotations

For some resources, the eks-controller supports annotations to customize the behavior of the controller. The following annotations are supported:

• Nodegroup

  • eks.services.k8s.aws/desired-size-managed-by: used to control whether the controller should manage the desiredSize of the Nodegroup spec.ScalingConfig.DesiredSize. It supports the following values:

    • ack-eks-controller: If set, the controller will be responsible for managing the desired size of the nodegroup.
    • external-autoscaler: If set, will ignore any changes to the spec.ScalingConfig.DesiredSize and will not manage the desired size of the nodegroup.

    If not set, the controller will default to ack-eks-controller.

  • eks.services.k8s.aws/force-update-version: used to force the version update of the nodegroup. If set to true, and the controller detects a a change in the nodegroup, it will set the force attribute to true in the UpdateNodeGroupConfig API call.
