Hey Dennis,
thank you for quick reaction and sorry for this late Response from my side. I have a Plugin which works only with Server and I would like to adapt it to Data Center. I used VirtualBox to set emulate a complete Data Center environment with 3 nodes and loadbalancer but since i found it very time-consuming to configure everything: jira/jiradatabase/loadbalancer/IP of the instances/… I wondered if I could simply everything with Docker and help me and other passionate developer who might not have deep system admin skills to setup docker/virtual data center environment. So instead i run my container and get a full data center Atlassian environment where i can install my plugin and test if my logic is doing exactly what I want.
Cheers
Yassin
