#  Run this as root on the first master node. You must be able to ssh as the root user to each node via ssh keys
#  installed at /root/.ssh/ on the first master node. The public ssh key MUST be in the /root/.ssh/authorized_keys
#  file on ALL nodes including the first master. Use "ssh-keygen" to create an ssh keypair and use "ssh-copy-id NODE_IP"
#  to distribute the public key to ALL nodes. The nodes also need to be configured for passwordless sudo, most cloud
#  providers and infrastructure provisioners do this by default.
#
#  The following commands are used to perpare a generic EC2 or GCE instance and run the script.

EKS on ARM

The xarm-install.sh script allows you to install and use Amazon EKS on ARM (xARM) with a single command.

Make sure you have aws, eksctl, kubectl, and jq installed. So far tested with bash on macOS.

chmod +x xarm-install.sh

./xarm-install.sh
