Details

Verify that the Docker server certificate key file (the file that is passed alongwith ‘–

tlskey’ parameter) is owned and group-owned by ‘root’.

The Docker server certificate key file should be protected from any tampering or unneeded

reads. It holds the private key for the Docker server certificate. Hence, it must be owned

and group-owned by ‘root’ to maintain the integrity of the Docker server certificate.

Solution

#> chown root-root This would set the ownership and group-ownership for the Docker server certificate key
file to ‘root’.

Impact-None.

Default Value-By default, the ownership and group-ownership for Docker server certificate key file is
correctly set to ‘root’.
