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 + +**--help**, **-h** + +Print usage statement. + +**--cert-dir**=*path* + +Use certificates at *path* (\*.crt, \*.cert, \*.key) to connect to the registry. +Default certificates directory is _/etc/containers/certs.d_. (Not available for remote commands) + +**--directory**, **-d**=*dir* + +Store the signatures in the specified directory. Default: /var/lib/containers/sigstore + +**--sign-by**=*identity* + +Override the default identity of the signature. + +## EXAMPLES +Sign the busybox image with the identify of foo@bar.com with a user's keyring and save the signature in /tmp/signatures/. + + sudo podman image sign --sign-by foo@bar.com --directory /tmp/signatures docker://privateregistry.example.com/foobar + +## RELATED CONFIGURATION + +The write (and read) location for signatures is defined in YAML-based +configuration files in /etc/containers/registries.d/. 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 --directory +option. For example, consider the following configuration file. + +docker: + privateregistry.example.com: + sigstore: file:///var/lib/containers/sigstore + +When signing an image preceded with the registry name 'privateregistry.example.com', +the signature will be written into sub-directories 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) |
