Hi, I am running docker inside of Ubuntu 16.04 (which is running inside Oracle virtual box). When I run mvn clean package docker:build docker:push, I got below error. I am using fabric8 plugin to push to docker repository. I have entered my credentials in maven settings.xml as well. Appreciate for your help
