Prerequisites

The instructions in this section assume that you will be running the commands to create and configure your AWS EKS cluster on a host that has been set up with the appropriate tools to do so.

AWS CLI tools

Nitro requires AWS CLI 2.x, so don’t use apt, yum or snap versions of the AWS CLI which install 1.x. You must use the AWS CLI installer from the link below:

$ curl "https://awscli.amazonaws.com/awscli-exe-linux-x86_64.zip" -o "awscliv2.zip"
$ unzip awscliv2.zip
$ sudo ./aws/install
$ sudo yum install git procps

Once you have the AWS CLI installed, you must configure it with your AWS credentials. When it asks for the “Default output format”, enter json:

$ aws configure
AWS Access Key ID [None]: [AWS Access Key ID]
AWS Secret Access Key [None]: [AWS Secret Access Key]
Default region name [None]: us-east-2
Default output format [None]: json

Docker

Follow the official instructions to install Docker for your platform:

https://docs.docker.com/engine/install/

kubectl

The official instructions for installing kubectl are here: https://kubernetes.io/docs/tasks/tools/install-kubectl/

Anjuna supports EKS versions 1.19 through 1.22. Ideally, you should install a version of kubectl that exactly matches the EKS version you wish to use, but using up to one minor version lower is supported. Using a kubectl version newer than your EKS version is not supported. For more details, see this page: https://kubernetes.io/releases/version-skew-policy/#kube-controller-manager-kube-scheduler-and-cloud-controller-manager

The following commands will set up your Linux host with kubectl v1.22:

$ curl -LO "https://dl.k8s.io/release/v1.22.9/bin/linux/amd64/kubectl"
$ sudo install -o root -g root -m 0755 kubectl /usr/local/bin/kubectl

# If /usr/local/bin is not in your PATH, and bash is your shell, you can add it like this:
$ export PATH=$PATH:/usr/local/bin
$ echo 'export PATH=$PATH:/usr/local/bin' >> ~/.bashrc

# Verify that kubectl reports the version you installed
$ kubectl version --client

Install Terraform

Install an up-to-date version of Terraform. Directions to install Terraform are here: https://learn.hashicorp.com/tutorials/terraform/install-cli

Install Helm
