Docker Question

Hi

I see this in the IDE Event Log.   I am not sure I understand what it means.   Can someone please elaborate with a bit of detailsm

8:45 AM File type recognized: File extension Dockerfile was reassigned to Dockerfile Revert

8:46 AM Dockerfile detection
You may setup Docker deployment run configuration for the following file(s):
C:\DEV\workspace\MyApp\Dockerfile
Disable this notification (show balloon)

I do have a decker file in the project and it looks like this

FROM java:8
EXPOSE 9090
ADD /target/MyApp-0.0.jar MyAppDocker.jar
ENTRYPOINT ["java","-jar", "MyAppDocker.jar"]

Is something wrong that I need to be aware of ... I am still trying to learn how to make use of docker.

Thanks for the help
