Overview

The configauditreport package provides primitives for working with Kubernetes workload configuration checkers.

Types

type Builder

type Builder interface {
	Controller(controller metav1.Object) Builder
	PodSpecHash(hash string) Builder
	PluginConfigHash(hash string) Builder
	Result(result v1alpha1.ConfigAuditResult) Builder
	Get() (v1alpha1.ConfigAuditReport, error)
}

func NewBuilder

func NewBuilder(scheme *runtime.Scheme) Builder

type Plugin

type Plugin interface {

	// GetScanJobSpec describes the pod that will be created by Starboard when
	// it schedules a Kubernetes job to scan the specified workload client.Object.
	// The plugin might return zero to many v1.Secret objects which will be
	// created by Starboard and associated with the scan job.
	GetScanJobSpec(ctx starboard.PluginContext, obj client.Object) (corev1.PodSpec, []*corev1.Secret, error)

	// ParseConfigAuditReportData is a callback to parse and convert logs of
	// the container in a pod controlled by the scan job to v1alpha1.ConfigAuditResult.
	ParseConfigAuditReportData(logsReader io.ReadCloser) (v1alpha1.ConfigAuditResult, error)

	// GetContainerName returns the name of the container in a pod created by a scan job
	// to read logs from.
	GetContainerName() string

	// GetConfigHash returns hash of the plugin's configuration settings. The computed hash
	// is used to invalidate v1alpha1.ConfigAuditReport object whenever configuration changes.
	GetConfigHash(ctx starboard.PluginContext) (string, error)
}

Plugin defines the interface between Starboard and Kubernetes workload configuration checkers / linters / sanitizers. Not a final version, rather first step to separate generic workloads discovery code and Polaris implementation details.

type ReadWriter

type ReadWriter interface {
	Writer
	Reader
}

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(ctx context.Context, owner kube.Object) (*v1alpha1.ConfigAuditReport, error)
	FindByOwnerInHierarchy(ctx context.Context, owner kube.Object) (*v1alpha1.ConfigAuditReport, error)
}

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

FindByOwner returns a v1alpha1.ConfigAuditReport owned by the given kube.Object or nil if the report is not found.

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

type Scanner

type Scanner struct {
	ext.IDGenerator
	// contains filtered or unexported fields
}

func NewScanner

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

func (*Scanner) Scan

func (s *Scanner) Scan(ctx context.Context, workload kube.Object) (v1alpha1.ConfigAuditReport, error)

type Writer

type Writer interface {
	Write(ctx context.Context, report v1alpha1.ConfigAuditReport) error
}

Writer is the interface that wraps the basic Write method.

Write creates or updates the given v1alpha1.ConfigAuditReport instance.
