-We need to store a password for Event Stream Service client. Since the server(s) will change along with the password, we will store the server and credentials in a secret per environment (DEV, TEST, PROD) and whether we connect with WebSockets or NATS protocols Pull requests can use the same as DEV.
+We need to store a username/password for Event Stream Service client. Additional configuration (Stream name, servers, stream limits) is in a Config Map: `chefs-XXX-event-stream-service`.
