Chapter 2: Managing State in Containers

1. The container layer is the top writeable layer in the filesystem for each Docker container.
2. Bind mounts provide a simple functionality of mounting any file or directory from the container host to a given container. Volumes provide similar functionality but they are fully managed by Docker, so you do not have to worry about physical paths in the container host filesystem.

3. The writeable container layer is coupled with the container host, which means it is not possible to easily move the data to a different host. Layer filesystems provide worse performance than direct access to the host filesystem (for example, using volumes). You cannot share the writeable layer between different containers.
4. Use the SMB Global Mapping feature on Windows host, which is provided to mount SMB shares visible to the containers. Then, you can mount the SMB...
