Mount point not found

Question

I am running a Java EE 7 application (with a lot of classes) on WildFly with Jackson, CDI, Swagger and Drools. I think that this error originated when I started using Drools, however I am not certain. As there is no reference to a local class, I have no idea where the error originated.

AFAIK, the application works without problems, but when I deploy the application, I get the following error:

I am using Docker Desktop for Windows. Can anyone help me out where to look for a solution, where this error is coming from?

Answer 1

I had this error in the last days using the elasticsearch docker image in Docker for Mac. I have fixed the issue change the storage driver from overlay2 to aufs (not sure yet about the real impact of this change). You can change the store driver:

• Docker preferences
• Daemon tab
• Advanced tab

• Edit the json like this:

  { "storage-driver" : "aufs" }

I hope it helps you
