Installing or updating eksctl
This topic helps you install or update eksctl, a simple command line tool for creating
and managing Kubernetes clusters on Amazon EKS. eksctl provides the fastest and easiest
way to create a new cluster with nodes for Amazon EKS. For more information and to see the
official documentation, see https://eksctl.io/.
Prerequisite
The kubectl command line tool is installed on your device or
AWS CloudShell. The version can be the same as or up to one minor version earlier or later than
the Kubernetes version of your cluster. For example, if your cluster version is 1.23, you can use kubectl version 1.22, 1.23, or 1.24 with it. To
install or upgrade kubectl, see Installing or updating kubectl.
To install or update eksctl
-
Determine whether you already have eksctl installed on your device.
eksctl version
If you have eksctl installed in the path of your device, the example output is
as follows. If you want to update the version that you currently have installed with
a later version, complete the next step, making sure to install the new version in
the same location that your current version is in.
0.129.0
If you receive no output, then you either don't have eksctl installed, or it's
not installed in a location that's in your device's path.

To install or update eksctl on
macOS
The easiest way to get started with Amazon EKS and macOS is by
installing eksctl with Homebrew, an open-source tool that can be
installed using these
instructions. The eksctl Homebrew recipe installs
eksctl and any other dependencies that are required for Amazon EKS,
such as kubectl. The recipe also installs the aws-iam-authenticator, which is
required if you don't have the AWS CLI version
1.16.156 or higher installed.
-
If you don't already have Homebrew installed on macOS, install
it with the following command.
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"
-
Install or upgrade eksctl. If eksctl is already installed,
the following command upgrades and relinks it. Or if eksctl
isn't installed yet, the following command installs
Weaveworks
Homebrew tap as needed, and then installs
eksctl.
brew upgrade eksctl && { brew link --overwrite eksctl; } || { brew tap weaveworks/tap; brew install weaveworks/tap/eksctl; }
-
Test that your installation was successful with the following
command.
eksctl version
