A fully-managed deploy pipeline to deploy to staging or production environments
Can deploy to EC2, On-Premise, Lambda or ECS
Can Perform In-Place or Blue/Green deployments
In-Place - instances are briefly taken offline, updates are applied to existing servers
Blue/Green- Replaces instances with new instances. Swapping environments
CodeDeploy Core Components:
Application encompasses all other components. Unique ID of the application being deployed
Deployment Groups -A set of EC2 instances or Lambda Functions where the new revision is deployed to
Deployments - This is the process and components used to apply a new application revision
Deployment Configuration- A set of deployment rules used during deployment with success/failure conditions included
AppSpec File - Contains the deployment actions that CodeDeploy should execute during deployment
Revision - This is everything required to deploy a new version: AppSpec file, application files, config files, executables
The Appspec.yml describes the deploy instructions and must be part of the deploy artifact
You need to install the CodeDeployAgent on the EC2 instances so it can communicate with CodeDeploy
You need to CodeDeployServiceRole to your EC2 instance so they have permission to communicate to CodeDeploy and so CodeDeploy has permissions to replicate servers or ASGs.
