The official CLI for Amazon EKS
eksctl is a simple CLI tool for creating clusters on EKS - Amazon's new managed Kubernetes service for EC2. It is written in Go, and uses CloudFormation.
You can create a cluster in minutes with just one command – eksctl create cluster!
Need help? Join Eksctl Slack.
eksctl now supports EKS Auto Mode! EKS Auto Mode automates routine tasks for cluster compute, storage, and networking.
Version 0.195.0 or greater is required.
eksctl now supports EKS Hybrid Nodes! Hybrid Nodes enables you to run on-premises and edge applications on customer-managed infrastructure with the same AWS EKS clusters, features, and tools you use in the AWS Cloud.
Version 0.195.0 or greater is required.
eksctl is available to install from official releases as described below. We recommend that you install eksctl from only the official GitHub releases. You may opt to use a third-party installer, but please be advised that AWS does not maintain nor support these methods of installation. Use them at your own discretion.
You will need to have AWS API credentials configured. What works for AWS CLI or any other tools (kops, Terraform, etc.) should be sufficient. You can use ~/.aws/credentials file
or environment variables. For more information read AWS documentation.
You will also need AWS IAM Authenticator for Kubernetes command (either aws-iam-authenticator or aws eks get-token (available in version 1.16.156 or greater of AWS CLI) in your PATH.
The IAM account used for EKS cluster creation should have these minimal access levels.
| AWS Service | Access Level |
|---|---|
| CloudFormation | Full Access |
| EC2 | Full: Tagging Limited: List, Read, Write |
| EC2 Auto Scaling | Limited: List, Write |
| EKS | Full Access |
| IAM | Limited: List, Read, Write, Permissions Management |
| Systems Manager | Limited: List, Read |
The inline policy json is listed in Minimal IAM Policies.
To download the latest release, run:

Make sure to unzip the archive to a folder in the PATH variable.
Optionally, verify the checksum:

The eksctl executable is placed in $HOME/bin, which is in $PATH from Git Bash.
For every release and RC a container image is pushed to ECR repository public.ecr.aws/eksctl/eksctl. Learn more about the usage on ECR Public Gallery - eksctl. For example,
docker run --rm -it public.ecr.aws/eksctl/eksctl version
brew tap weaveworks/tap brew install weaveworks/tap/eksctl
port install eksctl
choco install eksctl
scoop install eksctl
To create a basic cluster, run:
eksctl create cluster
A cluster will be created with default parameters
m5.large nodes (this instance type suits most common use-cases, and is good value for money)us-west-2 regionOnce you have created a cluster, you will find that cluster credentials were added in ~/.kube/config. If you have kubectl as well as aws-iam-authenticator commands in your PATH, you should be
able to use kubectl. You will need to make sure to use the same AWS API credentials for this also. Check EKS docs for instructions.
