3.14 Verify that docker-storage environment file permissions are set to 644 or more restrictive

Information

If you are using Docker on a machine that uses systemd to manage services, then verify that
the 'docker-storage' file permissions are correctly set to '644' or more restrictive.

'docker-storage' file contains sensitive parameters that may alter the behavior of Docker
daemon. Hence, it should not be writable by any other user other than 'root' to maintain
the integrity of the file.

Solution

#> chmod 644 /etc/sysconfig/docker-storage
This would set the file permissions to '644'.

Impact-None.

Default Value-This file may not be present on the system. In that case, this recommendation is not
applicable. By default, if the file is present, the file permissions are correctly set to '644'.
