Types

type Hashable

type Hashable interface {
	Checksum() ([]byte, error)
}

type VerificationResult

type VerificationResult struct {
	// VerificationResultType has 4 types which is corresponding to 4 cases:
	// 0 (VerificationSkip): The verification was skipped. Err is nil in this case.
	// 1 (VerificationPass): The verification passed. Err is nil in this case.
	// 2 (VerificationWarn): A warning is logged. It could be no matching policies and feature flag "no-match-policy" is "warn", or only Warn mode verification policies fail.
	// 3 (VerificationError): The verification failed, it could be the signature doesn't match the public key, no matching policies and "no-match-policy" is set to "fail" or there are errors during verification.
	VerificationResultType VerificationResultType
	// Err contains the error message when there is a warning logged or error returned.
	Err error
}

VerificationResult contains the type and message about the result of verification

func VerifyPipeline

func VerifyPipeline(ctx context.Context, pipelineObj *v1beta1.Pipeline, k8s kubernetes.Interface, refSource *v1.RefSource, verificationpolicies []*v1alpha1.VerificationPolicy) VerificationResult

VerifyPipeline is the deprecated, this is to keep backward compatibility

func VerifyResource

func VerifyResource(ctx context.Context, resource metav1.Object, k8s kubernetes.Interface, refSource *v1.RefSource, verificationpolicies []*v1alpha1.VerificationPolicy) VerificationResult

VerifyResource verifies the signature and public key against resource (v1beta1 and v1 task and pipeline). VerificationResult is returned with different types for different cases: 1) Return VerificationResult with VerificationSkip type, when no policies are found and no-match-policy is set to ignore 2) Return VerificationResult with VerificationPass type when verification passed; 3) Return VerificationResult with VerificationWarn type, when no matching policies and feature flag "no-match-policy" is "warn", or only Warn mode verification policies fail. Err field is filled with the warning; 4) Return VerificationResult with VerificationError type when no policies are found and no-match-policy is set to fail, the resource fails to pass matched enforce verification policy, or there are errors during verification. Err is filled with the err. refSource contains the source information of the resource.

func VerifyTask

func VerifyTask(ctx context.Context, taskObj *v1beta1.Task, k8s kubernetes.Interface, refSource *v1.RefSource, verificationpolicies []*v1alpha1.VerificationPolicy) VerificationResult

VerifyTask is the deprecated, this is to keep backward compatibility

type VerificationResultType

type VerificationResultType int

VerificationResultType indicates different cases of a verification result
