Warning: Do not directly manipulate any files or directories within Six directories under /var/lib/docker/overlay2. Image and container layers on-diskĪfter downloading a five-layer image using docker pull ubuntu, you can see ThisĬapability provides better performance for layer-related Docker commands suchĪs docker build and docker commit, and consumes fewer inodes on the backingįilesystem. The overlay2 driver natively supports up to 128 lower OverlayFS layers. OverlayFS refers to the lower directoryĪs lowerdir and the upper directory a upperdir.

These directories are called layers and the unification OverlayFS layers two directories on a single Linux host and presents them asĪ single directory. If you are still using the overlay driver rather than overlay2, see Its compatibility with different backing filesystems. Need to use the legacy overlay driver, specify it instead.ĭocker is now using the overlay2 storage driver and has automaticallyĬreated the overlay mount with the required lowerdir, upperdir, merged,Ĭontinue reading for details about how OverlayFS works within your DockerĬontainers, as well as performance advice and information about limitations of

The overlay and overlay2 drivers are supported on xfs backing filesystems, To use the overlay driver, which is not recommended. Version 3.10.0-514 of the kernel or higher. Version 4.0 or higher of the Linux kernel, or RHEL or CentOS using.OverlayFS is the recommended storage driver, and supported if you meet the following Note: For fuse-overlayfs driver, check Rootless mode documentation. Or RHEL or CentOS using version 3.10.0-514 and above.įor more information about differences between overlay vs overlay2, check To use the new driver, you need version 4.0 or higher of the Linux kernel, Overlay driver, because it is more efficient in terms of inode utilization. Note: If you use OverlayFS, use the overlay2 driver rather than the This topic refers to the Linux kernel driver as OverlayFS and to the Docker OverlayFS: the original overlay, and the newer and more stable overlay2. OverlayFS is a modern union filesystem that is similar to AUFS, but fasterĪnd with a simpler implementation.
