dynamic ip address

Question

Hi, 
I've a project to finish. My customer wants my docker containers's ip addresses has to change with a click. This is my first time in cloud. Is this possible, a dockerized running app's ip address can be changed. It can destroy and redeploy, but is this possible with a java based automatization. What should i study if it is possible. 
My app is spring boot micro service.

Answer

If you'd like to dynamically change the public IP address of the app, you might find [Elastic IP](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/elastic-ip-addresses-eip.html) useful.

The creation and allocation of these can also be automated using Java: https://docs.aws.amazon.com/sdk-for-java/latest/developer-guide/examples-ec2-elastic-ip.html
