Working with containers without volumes is only half of the story of what Docker is capable of doing, and when throwing the Docker module for Ansible, there are a few more things to learn.
Throughout this blog post, we will explore how to manage volumes with the Docker CLI. When you use Docker for development and testing purposes, it can be helpful to have a persistent volume so that you don’t lose your work when the container is destroyed or stopped.
When running storage volumes inside Docker containers, we can check the size of the volumes our containers are using.
In a Docker container, the storage is provided to each process as a virtualized block device. All containers share this same storage resource from their host machine.
