Like the other services we have covered, we will be running a quick hello world example. This will introduce you to the difference between OpenFaaS and the other tools. We will also find out why we needed to install Docker. To start with, run the following commands:
$ mkdir hello$ cd hello$ faas-cli new --lang python hello

Next, we need to log into a Docker Hub account. To do this, run the following command:
$ docker login
If you do not have a Docker Hub account, you can sign-up for one at https://hub.docker.com/ ...
