Starting the Lab
================

*Insert instructions here to access UDF*

Using NGINX with Docker
=======================

#. We will start by running an NGINX instance in docker on our Linux host.  To do this type the following commands on the Linux Shell.

   .. code-block:: shell

      docker run -i -t nginx /usr/bin/njs

#. The output will be as follows:

   .. code-block:: none

      interactive njs 0.2.4

      v.<Tab> -> the properties and prototype methods of v.
      type console.help() for more information

#. To test that the docker instance is running type the following command and you will recieve the output below:

   .. code-block:: none

      >> function hi(msg) {console.log(msg)}
      undefined
      >> hi("Hello world")
      'Hello world'
      undefined

#. Now type <CTRL> d to stop the interactive docker instance.

Downloading Lab Files
=====================

#. We will download the lab njs example and conf files from github by running the following command:

   .. code-block:: shell

      git clone https://github.com/xeioex/njs-examples
      cd njs-examples

#. Now type 'ls *' to show the files that were just downloaded to your Linux box.  The output is as follows:

   .. code-block:: shell

      ls *
