2024-08-14
Understand the Overlay Filesystem, a powerful tool that allows you to layer multiple filesystems to create a merged view. Start by learning how to set up an Overlay Filesystem and explore how various filesystem operations like reading, writing, and deleting files are managed within this structure. Discover how modifications in the merged view affect the underlying layers, including adding or removing files. Additionally, you'll delve into advanced topics such as using multiple lower directories and removing the Overlay Filesystem when it’s no longer needed. Finally, see how the Overlay Filesystem is closely related to Docker, where it plays a crucial role in managing container storage efficiently.
