Explanation
If the CodeDeploy agent is not running on the instances, it cannot carry out the deployment process, leading to failure and health constraints errors. Instances need to pass health checks during deployment. If they are not set up properly for health checks, CodeDeploy will report failures and might result in a HEALTH-CONSTRAINTS error.
