Part 7: Save Windows Container As A Docker Image

In this article, I’ll show how I create a new Window Server Container, Install IIS Web Server and save the container as a Docker Image.

By saving my Container as an Image, next time I would like to spin a new Windows Container with IIS Web Server I could use the custom Image and start an IIS Windows Container In a matter of seconds Instead of creating a new Windows Server container and then Install IIS.

The Docker Engine terminology for this process called Commit Which Is like creating a Gold Image using WDS.

To process of creating a Docker Image Is:

  • create a Windows Container
  • Install IIS
  • Stop the container
  • Run the commit command and save the Image

Below, I’ll create a new Windows Container called Win02 with shared Volume

docker run -it --name win02 -p 80:80 -p 443:443 -v c:\programdata\docker\volumes\data01:c:\data01 microsoft/windowsservercore cmd

Once I enter the container, I’ll start PowerShell and Install IIS Web Server

Powershell
Add-WindowsFeature web-server

Once IIS Is Installed I’ll exit the Container using

Ctrl + p + q

Next, I’ll stop the container:

docker stop win02

Check the container Docker ID using the line below:

docker ps -a

And finally, Commit the container as an Image:

docker commit e7f14ce404fa windowsiis/image.v2

When done, If I take a look of all the Images I’ll see my new Image

Docker images
