Types

type Condition

type Condition int

Condition defines condition type

const (
	//NotEvaluate to not evaluate condition
	NotEvaluate Condition = 0
	// Process to evaluate condition
	Process Condition = 1
	// Skip to ignore/skip the condition
	Skip Condition = 2
)

type PolicyController

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

PolicyController is responsible for synchronizing Policy objects stored in the system with the corresponding policy violations

func NewPolicyController

func NewPolicyController(kyvernoClient *kyvernoclient.Clientset,
	client *client.Client,
	pInformer kyvernoinformer.ClusterPolicyInformer,
	npInformer kyvernoinformer.PolicyInformer,
	grInformer kyvernoinformer.GenerateRequestInformer,
	configHandler config.Interface,
	eventGen event.Interface,
	prGenerator policyreport.GeneratorInterface,
	policyReportEraser policyreport.PolicyReportEraser,
	namespaces informers.NamespaceInformer,
	log logr.Logger,
	resCache resourcecache.ResourceCache,
	reconcilePeriod time.Duration) (*PolicyController, error)

NewPolicyController create a new PolicyController

func (*PolicyController) Run

func (pc *PolicyController) Run(workers int, reconcileCh <-chan bool, stopCh <-chan struct{})

Run begins watching and syncing.

type ResourceManager

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

ResourceManager stores the details on already processed resources for caching

func NewResourceManager

func NewResourceManager(rebuildTime int64) *ResourceManager

NewResourceManager returns a new ResourceManager

func (*ResourceManager) Drop

func (rm *ResourceManager) Drop()

Drop drop the cache after every rebuild interval mins TODO: or drop based on the size

func (*ResourceManager) GetScope

func (rm *ResourceManager) GetScope(kind string) (bool, error)

GetScope gets the scope of the given kind return error if kind is not registered

func (*ResourceManager) ProcessResource

func (rm *ResourceManager) ProcessResource(policy, pv, kind, ns, name, rv string) bool

ProcessResource returns true if the policy was not applied on the resource

func (*ResourceManager) RegisterResource

func (rm *ResourceManager) RegisterResource(policy, pv, kind, ns, name, rv string)

RegisterResource stores if the policy is processed on this resource version

func (*ResourceManager) RegisterScope

func (rm *ResourceManager) RegisterScope(kind string, namespaced bool)

RegisterScope stores the scope of the given kind

type Validation

type Validation interface {
	Validate() (string, error)
}

Validation provides methods to validate a rule
