skopeo-standalone-sign(1)() skopeo-standalone-sign(1)() NAME skopeo-standalone-sign - Debugging tool - Publish and sign an image in one step. SYNOPSIS skopeo standalone-sign [options] manifest docker-reference key- fingerprint --output|-o signature DESCRIPTION This is primarily a debugging tool, useful for special cases, and usually should not be a part of your normal operational workflow; use skopeo copy --sign-by instead to publish and sign an image in one step. manifest Path to a file containing the image manifest docker-reference A docker reference to identify the image with key-fingerprint Key identity to use for signing OPTIONS See also skopeo(1) for options placed before the subcommand name. --help, -h Print usage statement --output, -o output file Write signature to output file. --passphrase-file=path The passphare to use when signing with the key ID from --sign-by. Only the first line will be read. A passphrase stored in a file is of questionable security if other users can read this file. Do not use this option if at all avoidable.
