gcloud alpha container binauthz

NAME: gcloud alpha container binauthz - manage attestations for Binary Authorization on Google Cloud Platform
SYNOPSIS: gcloud alpha container binauthz GROUP | COMMAND [ GCLOUD_WIDE_FLAG … ]
DESCRIPTION: (ALPHA) Binary Authorization is a feature which allows binaries to run on Google Cloud Platform only if they are appropriately attested. Binary Authorization is configured by creating a policy.
EXAMPLES: This example assumes that you have created a keypair using gpg, usually by running gpg --gen-key … , with Name-Email set to attesting_user@example.com for your attestor.
First, some convenience variables for brevity:

ATTESTING_USER = "attesting_user@example.com" DIGEST = "000000000000000000000000000000000000000000000000000000000000abcd" ARTIFACT_URL = "gcr.io/example-project/example-image@sha256: ${ DIGEST } " ATTESTOR_NAME = "projects/example-project/attestors/canary"

Export your key's fingerprint (note this may differ based on version and implementations of gpg):

gpg \ --with-colons \ --with-fingerprint \ --force-v4-certs \ --list-keys \ " ${ ATTESTING_USER } " | grep fpr | cut --delimiter = ':' --fields 10

This should produce a 40 character, hexidecimal encoded string. See https://tools.ietf.org/html/rfc4880#section-12.2 for more information on key fingerprints.

Create your attestation payload:

gcloud alpha container binauthz create-signature-payload \ --artifact-url = " ${ ARTIFACT_URL } " \ > example_payload.txt

Create a signature from your attestation payload:

gpg \ --local-user " ${ ATTESTING_USER } " \ --armor \ --clearsign \ --output example_signature.pgp \ example_payload.txt

Upload the attestation:

gcloud alpha container binauthz attestations create \ --public-key-id = ${ KEY_FINGERPRINT } \ --signature-file = example_signature.pgp \ --artifact-url = " ${ ARTIFACT_URL } " \ --attestor = ${ ATTESTOR_NAME }

List the attestation by artifact URL. --format can be passed to output the attestations as json or another supported format:

gcloud alpha container binauthz attestations list \ --artifact-url = " ${ ARTIFACT_URL } " \ --format = yaml --- - | -----BEGIN PGP PUBLIC KEY BLOCK----- Version: GnuPG v1 … SNIP … -----END PGP PUBLIC KEY BLOCK----- - | -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 … SNIP … -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 … SNIP … -----END PGP SIGNATURE-----

List all artifact URLs on the project for which Container Analysis Occurrences exist. This list includes the list of all URLs with BinAuthz attestations:

gcloud alpha container binauthz attestations list --- https://gcr.io/example-project/example-image@sha256:000000000000000000000000000000000000000000000000000000000000abcd …

Listing also works for kind=ATTESTATION_AUTHORITY attestations, just pass the attestor:

gcloud alpha container binauthz attestations list \ --artifact-url = " ${ ARTIFACT_URL } " \ --attestor = ${ ATTESTOR_NAME } \ --format = yaml …
