In this blog post, I’ll show you how to create a volume and mount it Into a Windows Container using Docker.
Mounting Images In Containers Is very Important because It gives the ability to copy, store and backup data from and to running containers.
Containers are not designed to store or keep data Inside them so It’s Very Important to make sure that Important data Is stored outside the Container.
In the past I’ve blogged about copying data to Windows Containers, This article will add another method.
In the example below, I have a very simple DockerFile with that will build an Image using Nano Server.
In the second line, I’m using the VOLUME command to create a Volume on the container host In the following page c:\programdata\docker\volumes
Below, I’ll use the docker build command to build the Image
docker build -t volume .
Once done, I’ll create a new Container from the Image
docker run --rm -it --name web001 volume:latest powershell
At the same time, docker will create the folder with the Container’s name Inside the Volume folder.
Below, you can see the volume I created In the DockerFile (Called data) and I’ll go ahead and create a file inside it.
And as you can see below, the file was created on the Container Host and not Inside the Container
