Most systems are composed of multiple applications. An orchestration mechanism is needed to start the applications when needed and in the correct order. A typical modern application may consist of a database such as MongoDB and a web service implemented using NodeJS. The web application may provide a number of API services accessible via a http ReST interface. Testing those services will require test tools that can send requests to the http interface and evaluate the results returned such as http status codes and response content.

 In our example today we are going to discuss how to create a simple web server (IIS) and run it in a container . We will also inject some of our custom HTML for the example. The prerequisite for this lab would be to have a Windows 2016 server running Docker.

Another Simple Windows Container Image and Instance Example

Once we have created the Windows 2016 server, we can logg into the Azure Portal and connect to the instance via RDP.  For our example, we will be creating a folder structure where at the root of C:/, there is a folder called “dockerlabs”. Under the c:/dockerlabs folder, we will also create the folder “env”.In this blog post, we will be outlining the concept “Dockerfile” and create a simple example to highlight the difference between container images and instances.  Of course, before we first need to make sure that we are using a Windows 2016 Server with containers feature enabled.  These are the steps shown in my previous article - "Deploying a Simple Windows Container in Azure".

Deploying a Simple Windows Container in Azure

With the release of Windows Server 2016, Microsoft has expanded its integration with Docker to include running Docker Windows Containers.  As I mentioned in my previous article, this now means that there we can now run both Docker FOR Windows and Docker ON Windows.

There are several prerequisites for installing Docker for Windows. Fortunately, Microsoft Azure already has a Windows Server 2016 with a containers template that will satisfy those requirements for you. We will go through an exercise to demonstrate what a general implementation of Docker for Windows would look like if you elected to use Azure for your computing needs.

Here is an interesting tidbit having to do with docker inspect. The inspect function will return metadata associated with the object identifier that you include. That object identifier may be a container id, image id, name or other resource.

Docker FOR Windows vs. Docker ON Windows Server

Business demand to use “Docker FOR Windows Server” is ramping up faster than ever. There is a good chance some of your enterprise workloads are Windows-based. How can your business benefit from the introduction of Docker’s solution for Windows intensive environments?

Way back in 2014, Docker and Microsoft joined forces to bring Docker to local Windows Servers and Azure’s cloud offering.  That combination has clearly paid off.  This year at DockerCon17 (in Austin from April 17th to the 20th – hope to see you there!), all of the hands-on labs will be hosted in Microsoft Azure.
