atomic-sign- Create a signature for an image


Only use atomic sign if you trust the remote registry which contains the image (preferably by being the only administrator of it).


atomic sign [-h|--help] [-d, --directory] [--sign-by] [-g, --gnupghome] [ image ... ]


atomic sign will create a local signature for one or more local images that have been pulled from a registry. By default, the signature will be written into a directory derived from the registry configuration files as configured by registry_confdir in /etc/atomic.conf.


-h --help
Print usage statement.
-d --directory
Store the signatures in the specified directory. Default: /var/lib/atomic/signature
Override the default identity of the signature. You can define a default in /etc/atomic.conf
with the key default_signer.
-g --gnupghome
Specify the GNUPGHOME directory to use for signing, e.g. ~/.gnupg. This
argument will override the value of gnupg_homedir in /etc/atomic.conf.
Defaults to the homedir or the uid defined in /proc/self/loginuid if it exists, or
$SUDO_UID if it is defined, or current UID.
