Functions

func GetScanJobName

func GetScanJobName(obj client.Object) string

func OrderedBy

func OrderedBy(less ...LessFunc) *multiSorter

OrderedBy returns a Sorter that sorts using the LessFunc functions, in order. Call its Sort method to sort the data.

func RegistryCredentialsSecretName

func RegistryCredentialsSecretName(obj client.Object) string

Types

type BySeverity

type BySeverity struct{ Vulnerabilities }

BySeverity implements sort.Interface by providing Less and using the Vulnerabilities.Len and Vulnerabilities.Swap methods of the embedded Vulnerabilities value.

func (BySeverity) Less

func (s BySeverity) Less(i, j int) bool

type LessFunc

type LessFunc func(p1, p2 *v1alpha1.VulnerabilityReport) bool

type Plugin

type Plugin interface {

	// Init is a callback to initialize this plugin, e.g. ensure the default
	// configuration.
	Init(ctx trivyoperator.PluginContext) error

	// GetScanJobSpec describes the pod that will be created by Trivy-operator when
	// it schedules a Kubernetes job to scan the workload with the specified
	// descriptor.
	// The second argument maps container names to Docker registry credentials,
	// which can be passed to the scanner as environment variables with values
	// set from returned secrets.
	GetScanJobSpec(ctx trivyoperator.PluginContext, workload client.Object, credentials map[string]docker.Auth) (
		corev1.PodSpec, []*corev1.Secret, error)

	// ParseVulnerabilityReportData is a callback to parse and convert logs of
	// the pod controlled by the scan job to v1alpha1.VulnerabilityScanResult.
	ParseVulnerabilityReportData(ctx trivyoperator.PluginContext, imageRef string, logsReader io.ReadCloser) (
		v1alpha1.VulnerabilityReportData, error)
}

Plugin defines the interface between Trivy-operator and static vulnerability scanners.

type ReadWriter

type ReadWriter interface {
	Reader
	Writer
}

func NewReadWriter

func NewReadWriter(client client.Client) ReadWriter

NewReadWriter constructs a new ReadWriter which is using the client package provided by the controller-runtime libraries for interacting with the Kubernetes API server.

type Reader

type Reader interface {
	FindByOwner(context.Context, kube.ObjectRef) ([]v1alpha1.VulnerabilityReport, error)
	FindByOwnerInHierarchy(ctx context.Context, object kube.ObjectRef) ([]v1alpha1.VulnerabilityReport, error)
}

Reader is the interface that wraps methods for finding v1alpha1.VulnerabilityReport objects.

FindByOwner returns the slice of v1alpha1.VulnerabilityReport instances owned by the given kube.ObjectRef or an empty slice if the reports are not found.

FindByOwnerInHierarchy is similar to FindByOwner except it tries to lookup v1alpha1.VulnerabilityReport objects owned by related Kubernetes objects. For example, if the given owner is a Deployment, but reports are owned by the active ReplicaSet (current revision) this method will return the reports.

type ReportBuilder

type ReportBuilder struct {
	// contains filtered or unexported fields
}

func NewReportBuilder

func NewReportBuilder(scheme *runtime.Scheme) *ReportBuilder

func (*ReportBuilder) Container

func (b *ReportBuilder) Container(name string) *ReportBuilder

func (*ReportBuilder) Controller

func (b *ReportBuilder) Controller(controller client.Object) *ReportBuilder

func (*ReportBuilder) Data

func (*ReportBuilder) Get

func (*ReportBuilder) PodSpecHash

func (b *ReportBuilder) PodSpecHash(hash string) *ReportBuilder

func (*ReportBuilder) ReportTTL

func (b *ReportBuilder) ReportTTL(ttl *time.Duration) *ReportBuilder

type ScanJobBuilder

type ScanJobBuilder struct {
	// contains filtered or unexported fields
}

func NewScanJobBuilder

func NewScanJobBuilder() *ScanJobBuilder

func (*ScanJobBuilder) Get

func (s *ScanJobBuilder) Get() (*batchv1.Job, []*corev1.Secret, error)

func (*ScanJobBuilder) WithAnnotations

func (s *ScanJobBuilder) WithAnnotations(annotations map[string]string) *ScanJobBuilder

func (*ScanJobBuilder) WithCredentials

func (s *ScanJobBuilder) WithCredentials(credentials map[string]docker.Auth) *ScanJobBuilder

func (*ScanJobBuilder) WithObject

func (s *ScanJobBuilder) WithObject(object client.Object) *ScanJobBuilder

func (*ScanJobBuilder) WithPlugin

func (s *ScanJobBuilder) WithPlugin(plugin Plugin) *ScanJobBuilder

func (*ScanJobBuilder) WithPluginContext

func (s *ScanJobBuilder) WithPluginContext(pluginContext trivyoperator.PluginContext) *ScanJobBuilder

func (*ScanJobBuilder) WithPodTemplateLabels

func (s *ScanJobBuilder) WithPodTemplateLabels(podTemplateLabels labels.Set) *ScanJobBuilder

func (*ScanJobBuilder) WithTimeout

func (s *ScanJobBuilder) WithTimeout(timeout time.Duration) *ScanJobBuilder

func (*ScanJobBuilder) WithTolerations

func (s *ScanJobBuilder) WithTolerations(tolerations []corev1.Toleration) *ScanJobBuilder

type Scanner

type Scanner struct {
	// contains filtered or unexported fields
}

Scanner is a template for running static vulnerability scanners that implement the Plugin interface.

func NewScanner

func NewScanner(
	clientset kubernetes.Interface,
	client client.Client,
	plugin Plugin,
	pluginContext trivyoperator.PluginContext,
	config trivyoperator.ConfigData,
	opts kube.ScannerOpts,
) *Scanner

NewScanner constructs a new static vulnerability Scanner with the specified Plugin that knows how to perform the actual scanning, which is performed by running a Kubernetes job, and knows how to convert logs to instances of v1alpha1.VulnerabilityReport.

func (*Scanner) Scan

func (s *Scanner) Scan(ctx context.Context, workload kube.ObjectRef) ([]v1alpha1.VulnerabilityReport, error)

Scan creates a Kubernetes job to scan the specified workload. The pod created by the scan job has template contributed by the Plugin. It is a blocking method that watches the status of the job until it succeeds or fails. When succeeded it parses container logs and coverts the output to instances of v1alpha1.VulnerabilityReport by delegating such transformation logic also to the Plugin.

type Vulnerabilities

type Vulnerabilities []v1alpha1.Vulnerability

func (Vulnerabilities) Len

func (s Vulnerabilities) Len() int

func (Vulnerabilities) Swap

func (s Vulnerabilities) Swap(i, j int)

type WorkloadController

WorkloadController watches Kubernetes workloads and generates v1alpha1.VulnerabilityReport instances using vulnerability scanner that that implements the Plugin interface.

func (*WorkloadController) SetupWithManager

func (r *WorkloadController) SetupWithManager(mgr ctrl.Manager) error

type Writer

type Writer interface {
	Write(context.Context, []v1alpha1.VulnerabilityReport) error
}

Writer is the interface that wraps the basic Write method.

Write creates or updates the given slice of v1alpha1.VulnerabilityReport instances.
