The signature will be written to a directory +derived from the registry configuration files in /etc/containers/registries.d. By default, the signature will be written into /var/lib/containers/sigstore directory. + +# OPTIONS +**-h** **--help** + Print usage statement. + +**-d** **--directory** + Store the signatures in the specified directory.

When you sign +an image, podman will use those configuration files to determine +where to write the signature based on the the name of the originating +registry or a default storage value unless overriden with the -d +option. For example, consider the following configuration file. + +docker: + privateregistry.example.com: + sigstore: file:///var/lib/containers/sigstore + +When signing an image preceeded with the registry name 'privateregistry.example.com', +the signature will be written into subdirectories of +/var/lib/containers/sigstore/privateregistry.example.com. The use of 'sigstore' also means +the signature will be 'read' from that same location on a pull-related function. + +# HISTORY +November 2018, Originally compiled by Qi Wang (qiwan at redhat dot com) |
