automatically pull build and tag docker image code example

Example 1: docker build from github repository

docker run -p 3000:3000 -e github='https://github.com/pmcdowell-okta/dockertest.git' -it oktaadmin/dockertest

Example 2: docker url image

For those trying to create a Google Cloud instance using the "Deploy a container image to this VM instance." option then the correct url format would be

docker.io/<dockerimagename>:version

The suggestion above of registry.hub.docker.com/library/<dockerimagename> did not work for me.

I finally found the solution here (in my case, i was trying to run docker.io/tensorflow/serving:latest)
