On each web server where you want to install the GroupWise Web Application, follow the instructions in Setting Up GroupWise Web
in the GroupWise Installation Guide.
When you have multiple Docker images for your GroupWise system, we recommend that you use DNS redirection to distribute connections between the multiple servers using round-robin by assigning the IP address of all of the GroupWise Web servers to a single DNS name like gwmail.yourcompanyname.com.
