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.

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 CLI (EKS 1.19)


sudo curl --silent --location -o /usr/local/bin/kubectl https://amazon-eks.s3.us-west-2.amazonaws.com/1.16.8/2020-04-16/bin/linux/amd64/kubectl

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

kubectl version --short --client

Update AWS CLI

Upgrade AWS CLI according to guidance in AWS documentation.

sudo pip install --upgrade awscli && hash -r

Install jq, envsubst (from GNU gettext utilities) and bash-completion

sudo yum -y install jq gettext bash-completion

Verify the binaries are in the path and executable

    which $command &>/dev/null && echo "[x] $command in path" || echo "[ ] $command NOT FOUND"
  done
