问题
I have crated a docker image for a simple Java-Spring MVC War file, (Docker Config below). I am able to run the using docker run command and also I do not see any errors in the log or trouble uploading war into internal registry in Openshift-minishift. I was able to pull the image in my Openshift-minishift console.

I do not see any unusual thing or exceptions in my pod's tomcat logs,also I can see exploded war in the pod's terminal.
I could not able to run the app with generated route,
回答1:
Finally I have resolved my issue, I've seen similar kind of issue that I faced here https://github.com/openshift/origin/issues/8702 .
Reason could be missing haproxy config for my generated router.
So I have uninstalled my minishift, and re-installed minishift using ansible-container
Now tomcat is up and running!!!
