On a deployed instance of SO, you can use the Camunda Cockpit to view BPMN 2.0 workflow definitions in the deployment, and to inspect running and completed process instances.
Logging In
Because port 8080 on the docker host machine is forwarded to port 8080 in the SO docker container you can log into the cockpit by browsing to this URL:
http://dockerhost:8080/camunda/app/admin/default/#/login
Where dockerhost is the docker host system.
If you can use a browser on the docker host system, then use a localhost address:
http://localhost:8080/camunda/app/admin/default/#/login
The user is "admin" and the password is the same as the jboss admin password, which is not displayed here.
Viewing Process Definitions
Use the drop-down menu next to the home icon and select the "Cockpit" option:
The number of deployed process definitions should be displayed. Click on it.
Now you should see an actual list of deployed process definitions. You can click on any of them to view them.
