Information
Verify that the daemon.json file ownership and group-ownership is correctly set to root.
Rationale:
daemon.json file contains sensitive parameters that may alter the behavior of docker daemon. Hence, it should be owned and group-owned by root to maintain the integrity of the file.
Solution
chown root:root /etc/docker/daemon.json
This would set the ownership and group-ownership for the file to root.
Impact:
None.
Default Value:
This file may not be present on the system. In that case, this recommendation is not applicable.
