1. Fork the repo
2. Get it working locally
3. implement the missing steps in .github/workflows/main.yaml
   1. Add supply chain scanning and fix any issues
   2. Add unit testing
4. Create base infra as per two objectives and target arch below
5. Get infra scripts and continious deployment working by implementing /infra/deploy.sh
6. Implement the /about page and watch it deploy end-to-end

• Create VPC: 10.0.0.0/22
• Get Github actions to deploy your IaC
• Create Pub subnet:
  • a: 10.0.0.0/24
• Create Pvt Subnets:
  • a: 10.0.2.0/24
• Create IGW
• Create Public Route Table

• Clickops a t3.micro instance in a public subnet with port 22,80,8080 open and ssh in
  • Use the infra/ec2-user-data.sh script to get your application working on there
  • ssh ec2-user@<instance-public-ip>
• Delete that instance and script a t3.micro instance into the private subnet
• script a Network load balancer (NLB)
• Connect load balancer to instance
• Test application via load-balancer

• Github actions getting started
• EJS templating https://ejs.co/
