Creating an HTTP-triggered Azure function

In this first example, we will create an HTTP-triggered Azure function. This means that you can browse to the page hosting the actual function:

1. To begin, we will create a new directory and navigate to that directory:

   mkdir http
   cd http

2. Now, we will initialize a function using the following command. The --docker parameter specifies that we will build our function as a Docker container. This will result in a Dockerfile being created for us. We will select the Python language, option 3 in the following screenshot:

   func init --docker

   This will create the required files for our function to work:

3. Next, we will create the actual function. Enter the following code and select the fifth option, HTTP trigger, and name the function python-http:

   func new

   This should result in an output like Figure 11.8:

4. The code of the function is stored in the directory...
