Verify that the daemon.json file permissions are correctly set to 644 or more restrictive. daemon.json file contains sensitive parameters that may alter the behavior of docker daemon. Hence, it should be writable only by root to maintain the integrity of the file. This file may not be present on the system. In that case, this recommendation is not applicable. |
