Immutable AWS Deployments with Packer and Jenkins
summary
Shows how to use Packer AMI builder plus shell provisioners to bake OpenJDK, Tomcat and a hello-world WAR into immutable AWS AMIs, then launch instances that immediately serve /hello without runtime provisioning. Builds run on a t2.micro build instance (Packer launches, snapshots EBS, then deregisters instance) and the process is run from a CI server — Jenkins job automates image builds. Notes storage cost for EBS snapshots and aims to eliminate SSH toil.
