Architecture

Resources Created by this Template

• Worker Node EC2 [WrokerNode]
• Master Node EC2 [MasterNode]
• Master Security Group [KuberentesSGMasterNode]
• Worker Secuirty Group [KuberentesSGWorkerNode]

Template Flow

1. Cloudformation Creates 2 Secuirty Groups for each of the nodes
2. After the Security Groups have been created, 2 EC2 Instances are initiated with 1 being Master and the other being Worker
3. As soon as the EC2 Instances run, it downloads this github repo and changes the permissions of the bash script files to executable
