Install Kubernetes Tools

Amazon EKS clusters require kubectl and kubelet binaries and the aws-cli or 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.

Install kubectl

export KUBECTL_VERSION=v1.21.2
sudo curl --silent --location -o /usr/local/bin/kubectl https://storage.googleapis.com/kubernetes-release/release/${KUBECTL_VERSION}/bin/linux/amd64/kubectl
sudo chmod +x /usr/local/bin/kubectl

Enable Kubectl bash_completion

kubectl completion bash >>  ~/.bash_completion
. /etc/profile.d/bash_completion.sh
. ~/.bash_completion

Set the AWS Load Balancer Controller version

echo 'export LBC_VERSION="v2.3.0"' >>  ~/.bash_profile
.  ~/.bash_profile

Install JQ and envsubst

sudo yum -y install jq gettext bash-completion moreutils

Installing YQ for Yaml processing

echo 'yq() {
  docker run --rm -i -v "${PWD}":/workdir mikefarah/yq "$@"
}' | tee -a ~/.bashrc && source ~/.bashrc

Verify the binaries are in the path and executable

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