My Pre-Setup

❖ Simple EC2 instance and AMI

❖ Nodejs as a service

❖ Codedeploy Agent

❖ http://docs.aws.amazon.com/codedeploy/latest/userguide/how-to-run-agent.html#how-to-run-agent-install

❖ AWS CLI

IAM Setup❖ User role

❖ User permissions to use codedeploy

❖ “codedeploy:*"

❖ Service Role — Grants permissions to AWS Services

❖ AWSCodeDeployRole

❖ Instance Role — Grants permission to EC2 Instances

❖ Attach to instance BEFORE you launch

DEMO TIME

Things To Know❖ No cost for Codedeploy

❖ Region Support: US East

❖ (N. Virginia) us-east-1

❖ US West (N. California)us-west-1

❖ US West (Oregon) us-west-2

❖ EU/APAC/South America

❖ Log files at /opt/codedeploy-agent/deployment-root/deployment-logs

❖ ApplicationStop failures

❖ Autoscaling failures on version mismatch

❖ Autoscaling instances should install the codedeploy agent on startup

FIN, ACK

❖ Just an introduction, lots more you can do!

❖ Thank you very much!

❖ Please introduce yourself
