#After Installation, Remember to install AWS CLI 2. Tried to add installation here but did not work as of 06/09/23
#Recommend creating an ansible playbook to configure terraform with aws cli 2 and kubectl installed. 06/09/23

Terraform + Vault + AWS CLI 2 + KUBECTL + Password Authentication
Remember to set password for terra user after signing in with the public key so that you can copy the ssh key via terminal (MacOS)
