Docker Certified Associate Certification Training Course - Storage Types

The video tutorial covers various Linux storage drivers and filesystems used with Docker. It begins with an introduction to overlay filesystems like overlay2, AUFS, and fuse overlayfs, highlighting their support across different Linux distributions. The tutorial then explores rootless Docker and the role of storage drivers such as device Mapper and overlay tool in Linux volume management. Finally, it delves into the BTRFS filesystem, detailing its features like block-level operations, thin provisioning, and snapshots, and its advantages for Docker environments.

Which storage driver is supported on Linux distributions and is used in Docker?

• overlay2

• fuse overlayfs

• AUFS

• BTRFS

What is the primary function of fuse overlayfs in Docker?

• To combine multiple block devices

• To enable thin provisioning

• To provide advanced volume management

• To support rootless Docker on hosts without rootless overlay2

Which storage driver is a kernel-based framework for volume management on Linux?

• BTRFS

• device mapper

• fuse overlayfs

• overlay2

What is a key feature of the BTRFS file system?

• AUFS compatibility

• Kernel-based volume management

• Copy-on-write snapshots

• Rootless Docker support

How does BTRFS enhance storage management?

• By enabling AUFS on older kernels

• By providing block-level operations and thin provisioning

• By supporting rootless Docker

• By integrating with Docker 1806
