Docker Certified Associate Certification Training Course - File System in Containers

The video tutorial explains how data is managed in Docker containers. It covers the concept of writable layers where data is stored temporarily and how committing changes can create additional layers. The role of drivers in managing the file system is discussed, along with the advantages of using volumes for data storage. Volumes are preferred as they do not increase container size and exist outside the container lifecycle, often being associated with the host system.
