Prepare MacOS for interacting with AWS EKS

Amazon EKS clusters require `kubectl` and `kubelet` binaries and the aws-iam-authenticator binary to allow IAM authentication for your `Kubernetes` cluster.

If you do not already have Homebrew installed on your Mac, install it with the following command.

bash

/usr/bin/ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

INSTALL KUBERNETES TOOLS

- kubectl

bash

brew install kubectl

- aws-iam-authenticator

bash

brew install aws-iam-authenticator

- jq

bash

brew install jq

- envsubst

bash

brew install gettext
brew link --force gettext

Verify

bash

for command in kubectl aws-iam-authenticator jq envsubst
  do
    which $command &>/dev/null && echo "$command in path" || echo "$command NOT FOUND"
  done

eksctl - a CLI for Amazon EKS

Instead of using AWS console to create EKS cluster, you can use a more simpler but powerfull tool.

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.

bash

brew tap weaveworks/tap
brew install weaveworks/tap/eksctl
