Service Discovery is a simple PHP command to collect and store AWS information such as EC2s and RDSs in the current region and save them with their credentials into an encrypted JSON file on S3. The script later notifies each service via SSH and executes the service discovery client on each instance. Each client downloads the JSON file and uses it to configure different applications. It can easily be automated through Rundeck or Jenkins to be executed after each deploy.
Service Discovery is part of AWS PHP Commands.
