Is it possible to deploy a docker hub publicly hosted image to Kubernetes Container Engine without uploading it to Containers Registery?

Question

Still new to Containers and Kubernetes here but I am dabbling with deploying a cluster on Google Containers Engine and was wondering if you can use a docker hub hosted image to deploy containers, so in my .yaml configuration file I'd say:

  ...
  image: hub.docker.com/r/my-team/my-image:latest
  ...

Is this possible? Or one has to download/build image locally and then upload it to Google Containers Registery?

Thanks so much

Yes, it is possible. The Replication Controller template or Pod spec image isn't special. If you specify image: redis you will get the latest tag of the official Docker Hub library Redis image, just as if you did docker pull redis.
