The container processes +can modify content within the mount point which is stored in the +container storage in a separate directory. In overlay terms, the source +directory will be the lower, and the container storage directory will be the +upper. Modifications to the mount point are destroyed when the container +finishes executing, similar to a tmpfs mount point being unmounted. + +Note: On **SELinux** systems, the rootfs needs the correct label, which is by default +**unconfined_u:object_r:container_file_t:s0**. |
