Yoana Ruseva 2016-09-09 08:41:10 UTC Doc Text overlay2 storage driver now available

The `overlay2` graph driver, along with `overlay` is an implementation of OverlayFS, a copy-on-write union file system that features page-cache sharing between snapshot volumes. However, `overlay2` is the more performant option. Currently, the driver requires SELinux to be disabled. Using the driver with SELinux enabled will not be supported by Red Hat.


To enable the driver, specify *overlay2* in the _/etc/sysconfig/docker-storage/setup_ file:

STORAGE_DRIVER=overlay2
Doc Type If docs needed, set a value Technology Preview

The overlay2 graph driver, along with overlay, is an implementation of OverlayFS, a copy-on-write union file system that features page-cache sharing between containers. However, overlay2 is the more performant option. Currently, the driver requires SELinux to be disabled in docker. overlay2 is available for docker as a Technology Preview feature.

To enable the driver, specify *overlay2* in the _/etc/sysconfig/docker-storage/setup_ file:
