CrashLoopBackOff: Docker image not running on Kubernates ? (ImagePullBackOff)

10/19/2016

I have a REST API application with the following maven and docker file.
I am using Jdk 8, latest Docker and Kubernates, latest minicubi , and work on latest Mac OS

I was able to create the docker image without any problem as well as deploy it on Kubernate. However here the status when I run kubectl get pods

NAME                                     READY     STATUS             RESTARTS   AGE employee-2271331337-vj6v2             0/1       CrashLoopBackOff   29         2h office365-email-3450521264-nrtkr      0/1       ImagePullBackOff   0          5h our-node-2-3162948349-lelwt 1/1       Running            0          23h

Then I run the following code to see the log kubectl logs e-office365-2271331337-vj6v2 -pand found the following log:

lugin-group-id>:[:]:.
