gcloud container binauthz

NAME
gcloud container binauthz - manage attestations for Binary Authorization on Google Cloud Platform
SYNOPSIS
gcloud container binauthzGROUP |COMMAND[GCLOUD_WIDE_FLAG …]
DESCRIPTION
Binary Authorization is a feature which allows binaries to run on Google CloudPlatform only if they are appropriately attested. Binary Authorization isconfigured by creating a policy.
EXAMPLES
This example assumes that you have created a keypair using gpg, usually byrunninggpg --gen-key …, withName-Email set toattesting_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 andimplementations of gpg):

gpg\--with-colons\--with-fingerprint\--force-v4-certs\--list-keys\"${ATTESTING_USER}"|grepfpr|cut--delimiter=':'--fields10

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

Create your attestation payload:

gcloudcontainerbinauthzcreate-signature-payload\--artifact-url="${ARTIFACT_URL}"\  >example_payload.txt

Create a signature from your attestation payload:

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

Upload the attestation:

gcloudcontainerbinauthzattestationscreate\--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 tooutput the attestations as json or another supported format:

gcloudcontainerbinauthzattestationslist\--artifact-url="${ARTIFACT_URL}"\--format=yaml----|-----BEGINPGPPUBLICKEYBLOCK-----Version:GnuPGv1    …SNIP…-----ENDPGPPUBLICKEYBLOCK------|-----BEGINPGPSIGNEDMESSAGE-----Hash:SHA1    …SNIP…-----BEGINPGPSIGNATURE-----Version:GnuPGv1    …SNIP…-----ENDPGPSIGNATURE-----

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

gcloudcontainerbinauthzattestationslist---https://gcr.io/example-project/example-image@sha256:000000000000000000000000000000000000000000000000000000000000abcd…

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

gcloudcontainerbinauthzattestationslist\--artifact-url="${ARTIFACT_URL}"\--attestor=${ATTESTOR_NAME}\--format=yaml…
