§Deploying to CloudCaptain and AWS
CloudCaptain lets you deploy your Play applications on AWS. It is based on 3 core principles: Immutable Infrastructure, Minimal Images and Blue/Green deployments.
CloudCaptain comes with native Play application support and works by turning your Play dist zip into a minimal VM image that can be deployed unchanged either on VirtualBox or on AWS. This image is generated on-the-fly in seconds and is about 100x smaller than a regular Linux system. It literally only contains your Play application, a JRE and the Linux kernel, reducing the security attack surface to the minimum possible.
CloudCaptain works with your AWS account and automatically provisions all the necessary AWS resources your application requires including AMIs, Elastic IPs, Elastic Load Balancers, Security Groups, Auto-Scaling Groups and EC2 instances.
§Prerequisites
Sign up for a free CloudCaptain account as well as a free AWS account and install the CloudCaptain command line client.
As CloudCaptain works with your AWS account, it first needs the necessary permissions to do so. So if you haven’t already done so, go to the CloudCaptain Console and connect your AWS account now.
§Build your Application
Package your app using the sbt dist command in your project directory.
§Deploy your Application
Every new CloudCaptain account comes with 3 environments: dev, test and prod. dev is for fast roundtrips locally on VirtualBox environment and test and prod are on AWS.
So let’s deploy the new zip file of your application to the prod environment on AWS:
myapp$ boxfuse run -env=prod
