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 starboard.PluginContext) error

	// GetScanJobSpec describes the pod that will be created by Starboard 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 starboard.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 starboard.PluginContext, imageRef string, logsReader io.ReadCloser) (
		v1alpha1.VulnerabilityReportData, error)
}

Plugin defines the interface between Starboard and static vulnerability scanners.

type ReadWriter 

type ReadWriter interface {
	Reader
	Writer
}

func NewReadWriter 

func NewReadWriter(resolver *kube.ObjectResolver) 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 (b *ReportBuilder) Data(data v1alpha1.VulnerabilityReportData) *ReportBuilder

func (*ReportBuilder) Get 

func (b *ReportBuilder) Get() (v1alpha1.VulnerabilityReport, error)

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 starboard.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,
	cm kube.CompatibleMgr,
	plugin Plugin,
	pluginContext starboard.PluginContext,
	config starboard.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 

type WorkloadController struct {
	logr.Logger
	etc.Config
	client.Client
	kube.ObjectResolver
	controller.LimitChecker
	kube.LogsReader
	kube.SecretsReader
	Plugin
	starboard.PluginContext
	ReadWriter
	starboard.ConfigData
}

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.
