This is useful if you are studying for you CKA, and are wanting to use Kubernetes The Hard Way (kthw) by Kelsey Hightower on AWS instead of on GCP

This code deploys and configures the network infrastructure for doing the labs. It covers some or all of the steps required in labs 3 and 4.

The idea is to be able to save time setting up the VPC, remote access, firewall rules, compute instances, and the client certs each time you want to do the lab.

The network consists of:

• 3 control nodes ips:
  • controller-0: 10.240.0.10
  • controller-1: 10.240.0.11
  • controller-2: 10.240.0.12
• 3 worker nodes ips:
  • worker-0: 10.240.0.20
  • worker-1: 10.240.0.21
  • worker-2: 10.240.0.22
• 3 pods ips:
  • pod-0: 10.200.0.0/24
  • pod-1: 10.200.1.0/24
  • pod-2: 10.200.2.0/24

1. Clone this repo and make a branch for yourself - or fork it
2. Read KTHW Lab 1. The tips on using tmux are very helpful.
3. Install client tools in KTHW Lab 2 on your laptop.
4. Update the main variables.tf with:
   • your SSH key name
   • your SSH public key value
   • your external / public IP address to add to the SSH allow security group
5. Run the terraform code after updating your variable values in the variables.tf file.
   • This will cover KTHW Lab 3.
   • Note the public IP address in the output. You'll need that later.
   • verify that you can SSH to the public IP of the controller-0 instance
6. Follow the steps in KTHW Lab 4, but run the kube-client-cert.py script to install the client certificates.
7. Follow the instructions in the remaining labs

Run gk e -p security-dev terraform -destroy when you are done working with your lab. You can recreate the network when you're ready to go again.
