Steps:

1. build images
2. yum install registry
3. retag images
docker tag mongodb localhost:5000/mongodb
docker tag rockmongo localhost:5000/rockmongo
4. push images
docker push localhost:5000/mongodb
docker push localhost:5000/rockmongo
5. launch pod
kubecfg -c multi-container.json create pods
6. test access.
