rpc CreateAttestor(CreateAttestorRequest) returns (Attestor)

Creates an attestor, and returns a copy of the new attestor. Returns NOT_FOUND if the project does not exist, INVALID_ARGUMENT if the request is malformed, ALREADY_EXISTS if the attestor already exists.

Authorization Scopes

Requires the following OAuth scope:

  • https://www.googleapis.com/auth/cloud-platform

For more information, see the Authentication Overview.

DeleteAttestor

rpc DeleteAttestor(DeleteAttestorRequest) returns (Empty)

Deletes an attestor. Returns NOT_FOUND if the attestor does not exist.

GetPolicy

rpc GetPolicy(GetPolicyRequest) returns (Policy)

A policy specifies the attestors that must attest to a container image, before the project is allowed to deploy that image. There is at most one policy per project. All image admission requests are permitted if a project has no policy.

AdmissionRule

An admission rule specifies either that all container images used in a pod creation request must be attested to by one or more attestors, that all pod creations will be allowed, or that all pod creations will be denied.

Images matching an admission whitelist pattern are exempted from admission rules and will never block a pod creation.

Fields
evaluation_mode

EvaluationMode

Required. How this admission rule will be evaluated.

require_attestations_by[]

string

Optional. The resource names of the attestors that must attest to a container image, in the format projects/*/attestors/*. Each attestor must exist before a policy can reference it. To add an attestor to a policy the principal issuing the policy change request must be able to read the attestor resource.

Note: this field must be non-empty when the evaluation_mode field specifies REQUIRE_ATTESTATION, otherwise it must be empty.

enforcement_mode

EnforcementMode

Required. The action when a pod creation is denied by the admission rule.

EnforcementMode

Defines the possible actions when a pod creation is denied by an admission rule.

Enums
ENFORCEMENT_MODE_UNSPECIFIED Do not use.
ENFORCED_BLOCK_AND_AUDIT_LOG Enforce the admission rule by blocking the pod creation.
DRYRUN_AUDIT_LOG_ONLY Dryrun mode: Audit logging only. This will allow the pod creation as if the admission request had specified break-glass.

EvaluationMode

Enums
EVALUATION_MODE_UNSPECIFIED Do not use.
ALWAYS_ALLOW This rule allows all all pod creations.
REQUIRE_ATTESTATION This rule allows a pod creation if all the attestors listed in 'require_attestations_by' have valid attestations for all of the images in the pod spec.
ALWAYS_DENY This rule denies all pod creations.

AdmissionWhitelistPattern

An admission whitelist pattern exempts images from checks by admission rules.

Fields
name_pattern

string

An image name pattern to whitelist, in the form registry/path/to/image. This supports a trailing * as a wildcard, but this is allowed only in text after the registry/ part.

Attestor

An attestor that attests to container image artifacts. An existing attestor cannot be modified except where indicated.

Fields
name

string

Required. The resource name, in the format: projects/*/attestors/*. This field may not be updated.

description

string

Optional. A descriptive comment. This field may be updated. The field may be displayed in chooser dialogs.

update_time

Timestamp

Output only. Time when the attestor was last updated.

user_owned_grafeas_note

UserOwnedGrafeasNote

This specifies how an attestation will be read, and how it will be used during policy enforcement.

AttestorPublicKey

An attestor public key that will be used to verify attestations signed by this attestor.

Fields
comment

string

Optional. A descriptive comment. This field may be updated.

id

string

The ID of this public key. Signatures verified by BinAuthz must include the ID of the public key that can be used to verify them, and that ID must match the contents of this field exactly. Additional restrictions on this field can be imposed based on which public key type is encapsulated. See the documentation on public_key cases below for details.

Union field public_key.

public_key can be only one of the following:

ascii_armored_pgp_public_key

string

ASCII-armored representation of a PGP public key, as the entire output by the command gpg --export --armor foo@example.com (either LF or CRLF line endings). When using this field, id should be left blank. The BinAuthz API handlers will calculate the ID and fill it in automatically. BinAuthz computes this ID as the OpenPGP RFC4880 V4 fingerprint, represented as upper-case hex. If id is provided by the caller, it will be overwritten by the API-calculated ID.

pkix_public_key

PkixPublicKey

A raw PKIX SubjectPublicKeyInfo format public key.

NOTE: id may be explicitly provided by the caller when using this type of public key, but it MUST be a valid RFC3986 URI. If id is left blank, a default one will be computed based on the digest of the DER encoding of the public key.

string

A token to retrieve the next page of results. Pass this value in the ListAttestorsRequest.page_token field in the subsequent call to the ListAttestors method to retrieve the next page of results.

PkixPublicKey

A public key in the PkixPublicKey format (see https://tools.ietf.org/html/rfc5280#section-4.1.2.7 for details). Public keys of this type are typically textually encoded using the PEM format.

Fields
public_key_pem

string

A PEM-encoded public key, as described in https://tools.ietf.org/html/rfc7468#section-13

signature_algorithm

SignatureAlgorithm

The signature algorithm used to verify a message against a signature using this key. These signature algorithm must match the structure and any object identifiers encoded in public_key_pem (i.e. this algorithm must match that of the public key).

SignatureAlgorithm

Represents a signature algorithm and other information necessary to verify signatures with a given public key. This is based primarily on the public key types supported by Tink's PemKeyType, which is in turn based on KMS's supported signing algorithms. See https://cloud.google.com/kms/docs/algorithms. In the future, BinAuthz might support additional public key types independently of Tink and/or KMS.

AdmissionRule

Required. Default admission rule for a cluster without a per-cluster, per- kubernetes-service-account, or per-istio-service-identity admission rule.

update_time

Timestamp

Output only. Time when the policy was last updated.

GlobalPolicyEvaluationMode

Enums
GLOBAL_POLICY_EVALUATION_MODE_UNSPECIFIED Not specified: DISABLE is assumed.
ENABLE Enables global policy evaluation.
DISABLE Disables global policy evaluation.

UpdateAttestorRequest

Request message for [BinauthzManagementService.UpdateAttestor][].

Fields
attestor

Attestor

Required. The updated attestor value. The service will overwrite the attestor name field with the resource name in the request URL, in the format projects/*/attestors/*.

Authorization requires the following IAM permission on the specified resource attestor:

  • binaryauthorization.attestors.update

UpdatePolicyRequest

Request message for [BinauthzManagementService.UpdatePolicy][].

Fields
policy

Policy

Required. A new or updated policy value. The service will overwrite the policy name field with the resource name in the request URL, in the format projects/*/policy.

Authorization requires the following IAM permission on the specified resource policy:

  • binaryauthorization.policy.update

UserOwnedGrafeasNote

An user owned Grafeas note references a Grafeas Attestation.Authority Note created by the user.

Fields
note_reference

string

Required. The Grafeas resource name of a Attestation.Authority Note, created by the user, in the format: projects/*/notes/*. This field may not be updated.

An attestation by this attestor is stored as a Grafeas Attestation.Authority Occurrence that names a container image and that links to this Note. Grafeas is an external dependency.

public_keys[]

AttestorPublicKey

Optional. Public keys that verify attestations signed by this attestor. This field may be updated.

If this field is non-empty, one of the specified public keys must verify that an attestation was signed by this attestor for the image specified in the admission request.

If this field is empty, this attestor always returns that no valid attestations exist.

delegation_service_account_email

string

Output only. This field will contain the service account email address that this Attestor will use as the principal when querying Container Analysis. Attestor administrators must grant this service account the IAM role needed to read attestations from the [note_reference][Note] in Container Analysis (containeranalysis.notes.occurrences.viewer).

This email address is fixed for the lifetime of the Attestor, but callers should not make any other assumptions about the service account email; future versions may use an email based on a different naming pattern.
