#This Source code helps to deploy K3s cluster with one master and one node setup And once k3s cluster is deployed it deploys webapplication along with ha-proxy ingress.

Prerequisite: Before you start following below steps create a sshkey pair for your local server where you're going to run this whole terraform code. Run "ssh-keygen -f sshkey" and keep entering.

Steps to be followed:

1. Clone repo "git clone https://sample_terraformapp.git"

2. Create a variable fine terraform.ftvars including AWS_ACCESS_KEY and AWS_SECRET_KEY of IAM user that you will be creating in AWS console.

3. Then run terraform init It will initialize the terraform based on the terraform source code.

4. Run terraform apply It will prompt for Entering "Yes", please enter the same.

5. ssh into "server" and get the contents of /var/lib/rancher/k3s/server/node-token Once the step 4 is done you will see in your AWS console the K3s cluster with master and worker is created. Login to the k3s_server.

6. ssh into "node" and edit script at /root/k3s.sh, replacing the endpoint URL with the internal VPC DNS/IP of the "server" and the node token taken from server as in step 3. And run script #sudo sh /root/k3s.sh

7. kubectl get nodes should show two nodes registered ###############################################################

Once this is done You will Can login to master/worker and run to validate the resource "kubectl get all --all-namespaces". Note: For the moment code is deploying application and haxproxy in master node the same can be shifted cut pasting the file provisioner and remote_exec provisioner from server section ot instance.tf to worker section which are copying application manifests and haxproxy.

The Application server Details can be verified with curl -I -H 'Host: foo.bar' 'http://<clusterIP/DNS_IP>:30279'
