I have a java web application (spring) running inside a docker.
After few days all the outgoing api calls start throwing UnknownHostException exception.
Just Restarting the docker solves the issue but then this again reoccurs after sometime.
Can you point it some direction where to look for the bug.
java.net.UnknownHostException: api.bankoncube.com

Following is the docker setup
um-cube :
