How do I set a valid ServiceDnsName in my docker-compose file when deploying to Service Fabric?
With the help of Microsoft support I was able to solve this issue.
The Application name was the problem. If you remove the "fabric:/" part of the application name it worked for me.
It is a documentation error. Microsoft support will update the documentation
At least now the VSTS steps works and is deployed to Service Fabric. I now get some errors in the Service Fabric itself but that is for another question.
