The bottom of Docker is a boot file system, Bootfs.The second layer is the root filesystem rootfs, located on the boot file system.In the traditional Linux boot process, the root filesystem is first read-only and is switched to read-write mode when the boot finishes and the integrity check is completed. But in Docker, the root filesystem is always read-only, and Docker
