usage: in-toto-run <named arguments> [options] \
-- <command> [args]
in-toto-run is the main command line interface for generating link
metadata while carrying out a supply chain step. To do this, it wraps the
passed command, and attempts to track all relevant information about the
wrapped command's execution. It records paths and hashes of 'materials' (files
before command execution) and 'products' (files after command execution) and
writes them together with other information (executed command, return value,
stdout and stderr) to a link metadata file, which is signed with the passed
key. It returns a non-zero value on failure and zero otherwise.
Required Named Arguments:
-n <name>, --step-name <name>
name for the resulting link metadata file, which is written to
'<name>.<keyid prefix>.link'. It is also used to associate the link with a
step defined in an in-toto layout.
-k <path>, --key <path>
path to a private key file to sign the resulting link metadata. The keyid
prefix is used as an infix for the link metadata filename, i.e.
'<name>.<keyid prefix>.link'. See '--key-type' for available formats.
Passing one of '--key' or '--gpg' is required.
-g [<id>], --gpg [<id>]
GPG keyid to sign the resulting link metadata. When '--gpg' is passed
without the keyid, the default GPG key is used. The keyid prefix is used
as an infix for the link metadata filename, i.e. '<name>.<keyid
prefix>.link'. Passing one of '--key' or '--gpg' is required.
Positional Arguments:
<command> command to be executed. It is separated from named and optional arguments
by a double dash '--'.
Options:
-h, --help show this help message and exit
-m <path> [<path> ...], --materials <path> [<path> ...]
paths to files or directories, for which paths and hashes are stored in
the resulting link metadata before the command is executed. Symlinks to
files are followed.
-p <path> [<path> ...], --products <path> [<path> ...]
paths to files or directories, for which paths and hashes are stored in
the resulting link metadata after the command is executed. Symlinks to
files are followed.
-s, --record-streams duplicate 'stdout' and 'stderr' of the executed command and store the
contents in the resulting link metadata. Do not use with interactive
commands.
-x, --no-command generate link metadata without executing a command, e.g. for a signed-off-
by step.
-t {rsa,ed25519,ecdsa}, --key-type {rsa,ed25519,ecdsa}
type of key specified by the '--key' option. 'rsa' keys are expected in a
'PEM' format. 'ed25519' and 'ecdsa' are expected to be in a custom
'securesystemslib/json' format. Default is 'rsa'.
-P [<password>], --password [<password>]
password for encrypted key specified with '--key'. Passing '-P' without
<password> opens a prompt. If no password is passed, or entered on the
prompt, the key is treated as unencrypted. (Do not confuse with
'-p/--products'!)
--gpg-home <path> path to a GPG home directory used to load a GPG key identified by '--gpg'.
If '--gpg-home' is not passed, the default GPG home directory is used.
--exclude <pattern> [<pattern> ...]
path patterns to match paths that should not be recorded as 'materials' or
'products'. Passed patterns override patterns defined in environment
variables or config files. See Config docs for details.
--base-path <path> base path for relative paths passed via '--materials' and '--products'. It
is used to locate and record artifacts, and is not included in the
resulting link metadata. Default is the current working directory.
--lstrip-paths <path> [<path> ...]
path prefixes used to left-strip artifact paths before storing them to the
resulting link metadata. If multiple prefixes are specified, only a single
prefix can match the path of any artifact and that is then left-stripped.
All prefixes are checked to ensure none of them are a left substring of
another.
-d <directory>, --metadata-directory <directory>
path to a directory to dump metadata. If '--metadata-directory' is not
passed, the current working direcotry is used.
--use-dsse generate metadata using dsse (experimental).
-v, --verbose show more output
-q, --quiet suppress all output
--version show program's version number and exit
EXAMPLE USAGE
Tag a git repo, storing files in CWD as products, signing the resulting link
file with the private key loaded from 'key_file'.
in-toto-run -n tag -p . -k key_file -- git tag v1.0
Create a tarball, storing files in 'project' directory as materials and the
tarball as product, signing the link file with a GPG key '...7E0C8A17'.
in-toto-run -n package -m project -p project.tar.gz \
-g 8465A1E2E0FB2B40ADB2478E18FB3F537E0C8A17 \
-- tar czf project.tar.gz project
Not all supply chain steps require that a command be executed. in-toto can
still generate signed attestations, e.g. for review work. In that case, files
may be marked as materials for the manual review process and the command be
omitted.
in-toto-run -n review -k key_file -m document.pdf -x
If an artifact that should be recorded is not in the current working directory
(or one of its subdirectories) it can be located using the base path option.
Note that in this example only the relative path, 'document.pdf' is stored
along with its hash in the resulting link metadata file.
in-toto-run -n review -k key_file -m document.pdf \
--base-path /my/review/docs/ -x
Similarly, it is possible to pass the full path to the artifact that should
be recorded together with a left-strip path, to only store a relative path,
e.g. 'document.pdf'.
in-toto-run -n review -k key_file \
-m /tmp/my/review/docs/document.pdf \
--lstrip-paths /tmp/my/review/docs/ -x
