In this blog post, I’ll show you how to create a basic Windows Container Image from a dockerFile using a Windows Nano Server Container Image.
What Is DockerFile
DockerFile Is a file without extension (based on Linux) that contains Instructions that are used to build Container Images.
To create the most basic docker file you will need to use only one line (From).
To create an Image from a DockerFile, I’ll create an empty folder on my C: Drive and will store the DockerFile.
Create a DockerFile
Next, I’ll create my dockerFile with all my Instructions and I’ll save it without any extension Inside the folder I created before.
In the file below, I’m creating a basic Docker Container Image made of Nano Server and mounting a volume Inside the Container.
FROM microsoft/nanoserver VOLUME web001:c:\\data
Running the DockerFile
To run my DockerFile, I’ll run the docker command below from the folder I created with the dockerFile Inside.
docker build --tag image101 .
Once the build process Is done, I can see the new Image using the command below
To run a new container from the new Image I’ll use the command below
docker -rm -it image101 powershell
Inside the container, I can see the data folder which Is mounted to the c:\data Inside the container
