Frequently Asked Questions (FAQ)

A Kubernetes distribution?

Question

What is a Kubernetes distribution and why do you call EKS Distro one?

Answer

EKS Distro is a distro of the same open source Kubernetes and dependencies deployed by Amazon EKS. We include binaries and containers of open source Kubernetes, etcd, networking, storage plugins, tested for compatibility. We provide extended support for Kubernetes versions after community support expires, by updating builds of previous versions with the latest critical security patches. You can securely access EKS Distro releases from GitHub or within AWS via Amazon S3 and ECR for a common source of releases and updates.

Is this a fork of Kubernetes?

Question

Is EKS Distro forking Kubernetes?

Answer

No. EKS Distro takes upstream (unmodified) Kubernetes and packages and configures it in a certain, opinionated manner. We've gathered these opinions by running tens of thousands of EKS clusters at different scales, world-wide.

Why use EKS Distro?

Question

Why should I use EKS Distro?

Answer

EKS Distro enables you to create Kubernetes clusters using a distro of compatible versions of the latest Kubernetes release and its dependencies, tested by Amazon EKS to be reliable and secure. With EKS Distro you have a single vendor for secure access to installable, reproducible builds of Kubernetes for cluster creation and extended security patching support of Kubernetes versions after community support expires. We will provide extended Kubernetes maintenance support for up to 14 months in accordance with Amazon EKS Version Lifecycle Policy providing you the timeframe necessary to update your infrastructure in alignment with your software lifecycle. For further information on supported Kubernetes versions in EKS, see Amazon EKS version support and FAQ.

What is included in EKS Distro?

Question

What is included in EKS Distro?

Answer

EKS Distro includes opensource (upstream) Kubernetes components and third-party tools including configuration database, network, and storage components necessary for cluster creation. They include Kubernetes control plane components (eg. kube-controller-manager, etcd, and CoreDNS), Kubernetes worker node components (eg. kubelet, CSI, and CNI), and command line clients (eg. kubectl and kubeadm).

What operating systems are supported?

Question

What operating system can I install EKS Distro on?

Answer

We provide the same upstream versions of Kubernetes and dependencies which operating system vendors have tested and confirmed to work with Kubernetes, and will work the same way. As a result, EKS Distro works with common operating systems already used to create Kubernetes clusters, such as CentOS, Canonical Ubuntu, Red Hat Enterprise Linux, Suse, and more. We are testing EKS Distro with select vendors to ensure support on Bottlerocket, Amazon Linux 2, and Canonical has tested EKS Distro for compatibility with Ubuntu.
