 To start the containerized Administration Server, run:
 
-    $ docker run -d --name wlsadmin --hostname wlsadmin -p 7001:7001 --env-file ./container-scripts/domain.properties 12213-domain-wdt
+    $ docker run -d --name wlsadmin --hostname wlsadmin -p 7001:7001 -v <sample-directory>/properties:/u01/oracle/properties 12213-domain-wdt
 
 To start a containerized Managed Server (ms-1) to self-register with the Administration Server above, run:
 
-    $ docker run -d --name ms-1 --link wlsadmin:wlsadmin -p 9001:9001 --env-file ./container-scripts/domain.properties -e ADMIN_PASSWORD=<admin_password> -e MS_NAME=ms-1 12213-domain-wdt startManagedServer.sh

 To start an additional Managed Server (in this example ms-2), run:
 
-    $ docker run -d --name ms-2 --link wlsadmin:wlsadmin -p 9002:9001 --env-file ./container-scripts/domain.properties -e ADMIN_PASSWORD=<admin_password> -e MS_NAME=ms-2 12213-domain-wdt startManagedServer.sh

 The above scenario from this sample will give you a WebLogic domain with a dynamic cluster set up on a single host environment.
