Chronograf doesn't load .dashbaord files correct from resources path

I try to load some dashbaord on start-up of my docker container. According to the documentation, it should load all .dashbaord files in the resource path. In the same directorie is the .src file for the source configuration, which gets loaded corretly.

Chronograf does load something, but it isn’t a usefull dahsboard. It is an empty dashbaord without any cells or even a name.

How is the correct process to generate a dashboard, that can later be loaded automatically on start-up?

I’m using chronograf v1.8.10.
