Install Kubernetes Tools

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

In this workshop we will give you the commands to download the Linux binaries. If you are running Mac OSX / Windows, please see the official EKS docs for the download links.

Create the default ~/.kube directory for storing kubectl configuration

mkdir -p ~/.kube

Install kubectl

sudo curl --silent --location -o /usr/local/bin/kubectl "https://amazon-eks.s3-us-west-2.amazonaws.com/1.11.5/2018-12-06/bin/linux/amd64/kubectl"

sudo chmod +x /usr/local/bin/kubectl

Install AWS IAM Authenticator

go get -u -v github.com/kubernetes-sigs/aws-iam-authenticator/cmd/aws-iam-authenticator
sudo mv ~/go/bin/aws-iam-authenticator /usr/local/bin/aws-iam-authenticator

Install JQ and envsubst

sudo yum -y install jq gettext

Verify the binaries are in the path and executable

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