Jenkins-Terraform-Packer-AWS

This Pipeline automates 3tier node app. "WEB --> API --> RDS". All build is deployed without downtime.

This does the following things:

1. Creates AMI using packer
2. Configuration Management using ansible
3. Deployment using terraform which includes following resources:
   1. ASG and ALB for API & WEB
   2. S3 Bucket for logs using cron
   3. RDS
   4. Cloudfront

Terraform is configured in a way that when a new build is made, a new AMI is created and New ASG and LC is created without downtime. i.e. new one is first created and then older one is destroyed.
