How to test?

When applied the configuration terraform will show us the next output:

Outputs:

db_endpoint = terraform-20181102155541101800000001.cfi372mmcqsi.us-east-1.rds.amazonaws.com:3306
web_server_public_ip = 18.209.111.9

Use the db_endpoint and web_server_public_ip for the next steps.

Open the Address Book Web App page

Find on EC2 the "IPv4 Public IP" address(web_server_public_ip) of the "Web Server" instance and open it in a web browser.

Login in the web app and try some CRUD operations

Find the DB endpoint( db_endpoint) on the "Connect" section of the RDS mysql created instance.

Using the DB endpoint and credentials(can be found on the 9-rdsDbResources.tf file) login in the app.

Create, edit or remove contacts to test the web app.
