kosli attest custom

Report a custom attestation to an artifact or a trail in a Kosli flow.

Synopsis

kosli attest custom [IMAGE-NAME | FILE-PATH | DIR-PATH] [flags]

Report a custom attestation to an artifact or a trail in a Kosli flow. The name of the custom attestation type is specified using the --type flag. The path to the JSON file the custom type will evaluate is specified using the --attestation-data flag.

The attestation can be bound to a trail using the trail name.
The attestation can be bound to an artifact in two ways:

• using the artifact’s SHA256 fingerprint which is calculated (based on the --artifact-type flag and the artifact name/path argument) or can be provided directly (with the --fingerprint flag).
• using the artifact’s name in the flow yaml template and the git commit from which the artifact is/will be created. Useful when reporting an attestation before creating/reporting the artifact.

You can optionally associate the attestation to a git commit using --commit (requires access to a git repo). You can optionally redact some of the git commit data sent to Kosli using --redact-commit-info. Note that when the attestation is reported for an artifact that does not yet exist in Kosli, --commit is required to facilitate binding the attestation to the right artifact.

Flags

Flag	Description
—annotate stringToString	[optional] Annotate the attestation with data using key=value.
-t, —artifact-type string	The type of the artifact to calculate its SHA256 fingerprint. One of: [oci, docker, file, dir]. Only required if you want Kosli to calculate the fingerprint for you (i.e. when you don’t specify ‘—fingerprint’ on commands that allow it).
—attachments strings	[optional] The comma-separated list of paths of attachments for the reported attestation. Attachments can be files or directories. All attachments are compressed and uploaded to Kosli’s evidence vault.
—attestation-data string	The filepath of a json file containing the custom attestation data.
-g, —commit string	[conditional] The git commit for which the attestation is associated to. Becomes required when reporting an attestation for an artifact before reporting it to Kosli. (defaulted in some CIs: docs ).
—description string	[optional] attestation description
-D, —dry-run	[optional] Run in dry-run mode. When enabled, no data is sent to Kosli and the CLI exits with 0 exit code regardless of any errors.
-x, —exclude strings	[optional] The comma separated list of directories and files to exclude from fingerprinting. Can take glob patterns. Only applicable for —artifact-type dir.
—external-fingerprint stringToString	[optional] A SHA256 fingerprint of an external attachment represented by —external-url. The format is label=fingerprint (labels cannot contain ’.’ or ’=’). This flag can be set multiple times. There must be an external url with a matching label for each external fingerprint.
—external-url stringToString	[optional] Add labeled reference URL for an external resource. The format is label=url (labels cannot contain ’.’ or ’=’). This flag can be set multiple times. If the resource is a file or dir, you can optionally add its fingerprint via —external-fingerprint
-F, —fingerprint string	[conditional] The SHA256 fingerprint of the artifact to attach the attestation to. Only required if the attestation is for an artifact and —artifact-type and artifact name/path are not used.
-f, —flow string	The Kosli flow name.
-h, —help	help for custom
-n, —name string	The name of the attestation as declared in the flow or trail yaml template.
-o, —origin-url string	[optional] The url pointing to where the attestation came from or is related. (defaulted to the CI url in some CIs: docs ).
—redact-commit-info strings	[optional] The list of commit info to be redacted before sending to Kosli. Allowed values are one or more of [author, message, branch].
—registry-password string	[conditional] The container registry password or access token. Only required if you want to read container image SHA256 digest from a remote container registry.
—registry-username string	[conditional] The container registry username. Only required if you want to read container image SHA256 digest from a remote container registry.
—repo-root string	[defaulted] The directory where the source git repository is available. Only used if —commit is used or defaulted in CI, see docs . (default ”.”)
-T, —trail string	The Kosli trail name.
—type string	The name of the custom attestation type.
-u, —user-data string	[optional] The path to a JSON file containing additional data you would like to attach to the attestation.

Flags inherited from parent commands

Flag	Description
-a, —api-token string	The Kosli API token.
-c, —config-file string	[optional] The Kosli config file path. (default “kosli”)
—debug	[optional] Print debug logs to stdout. A boolean flag docs (default false)
-H, —host string	[defaulted] The Kosli endpoint. (default “https://app.kosli.com”)
—http-proxy string	[optional] The HTTP proxy URL including protocol and port number. e.g. ‘http://proxy-server-ip:proxy-port’
-r, —max-api-retries int	[defaulted] How many times should API calls be retried when the API host is not reachable. (default 3)
—org string	The Kosli organization.
