Simple example of how to deploy Node.js application to AWS EC2 instance using AWS CodeDeploy and AWS CodePipeline services

Step By Step Guideline

---

1. Create a new IAM role for EC2 instance

1.1. Go to Create IAM Role Page

sudo chmod +x ./install
sudo ./install auto

1.6. Add a tag Name: YOUR_INSTANCE_NAME_HERE

1.6. Launch the instance

4. Create CodeDeploy Application
