 Our target is to deploy the demo in separated container images, so docker build is necessary steps. Thanks to the `docker run in docker` method, this example build could be done in Occlum development container image.

 Below command can do benchmark test for the tensorflow serving service running in Occlum.

 Try scale up the tensorflow serving pods number, better `tps` can be achieved.
