Create a Data Volume and Mount It on a Docker Container

In this blog post, I will show you how to create a data volume on a Docker host running on Linux CentOS.

Create Volume

I will start by creating a volume using the following docker command.

docker volume create app

I called the volume app.

Deploy Container and Mount Volume

To run a container and attach the volume to it I will use the following command:

docker container run -it -v data:/app centos /bin/bash

Using the above command I mounted the volume into the app directory inside the container.

Any data that I save inside the app directory is kept on the container host after I delete the container.
