Functions

func BaseLabels

func BaseLabels(cvc *apis.CStorVolumeConfig) map[string]string

BaseLabels returns the base labels we apply to cstorvolumereplicas created

func GetCVRList

func GetCVRList(clientset clientset.Interface, pvName, namespace string) (*apis.CStorVolumeReplicaList, error)

GetCVRList returns list of volume replicas related to provided volume

func GetPDBLabelSelector

func GetPDBLabelSelector(poolNames []string) string

GetPDBLabelSelector returns the labelSelector to list the PDB

func GetPDBLabels

func GetPDBLabels(poolNames []string, cspcName string) map[string]string

GetPDBLabels returns the labels required for building PDB based on arguments

func GetPDBPoolLabels

func GetPDBPoolLabels(poolNames []string) map[string]string

GetPDBPoolLabels returns the pool labels from poolNames

func GetVolumeReplicaPoolNames

func GetVolumeReplicaPoolNames(clientset clientset.Interface, pvName, namespace string) ([]string, error)

GetVolumeReplicaPoolNames return list of replicas pool names by taking pvName and namespace(where pool is installed) as a input and return error(if any error occured)

func MergeResizeConditionsOfCVC

func MergeResizeConditionsOfCVC(oldConditions, resizeConditions []apis.CStorVolumeConfigCondition) []apis.CStorVolumeConfigCondition

MergeResizeConditionsOfCVC updates cvc with desired resize conditions leaving other conditions untouched.

func Start

func Start() error

Start starts the cstorvolumeclaim controller.

Types

type CVCController

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

CVCController is the controller implementation for CVC resources

func (*CVCController) BuildTargetDeployment

func (c *CVCController) BuildTargetDeployment(
	vol *apis.CStorVolume,
	policySpec *apis.CStorVolumePolicySpec,
) (*appsv1.Deployment, error)

BuildTargetDeployment builds the target deploytment object for a given volume and policy

func (*CVCController) IsCVRPending

func (c *CVCController) IsCVRPending(cvc *apis.CStorVolumeConfig) (bool, error)

IsCVRPending look for pending cstorvolume replicas compared to desired replica count. returns true if count doesn't matches.

func (*CVCController) PatchCVCStatus

func (c *CVCController) PatchCVCStatus(oldCVC,
	newCVC *apis.CStorVolumeConfig,
) (*apis.CStorVolumeConfig, error)

PatchCVCStatus updates CVC status using patch api

func (*CVCController) Run

func (c *CVCController) Run(threadiness int, stopCh <-chan struct{})

Run will set up the event handlers for types we are interested in, as well as syncing informer caches and starting workers. It will block until stopCh is closed, at which point it will shutdown the workqueue and wait for workers to finish processing their current work items.

func (*CVCController) ShouldReconcile

func (c *CVCController) ShouldReconcile(cvc *apis.CStorVolumeConfig) (bool, string)

type CVCControllerBuilder

type CVCControllerBuilder struct {
	CVCController *CVCController
}

CVCControllerBuilder is the builder object for controller.

func NewCVCControllerBuilder

func NewCVCControllerBuilder() *CVCControllerBuilder

NewCVCControllerBuilder returns an empty instance of controller builder.

func (*CVCControllerBuilder) Build

func (cb *CVCControllerBuilder) Build() (*CVCController, error)

Build returns a controller instance.

type Patch

type Patch struct {
	Op    string `json:"op"`
	Path  string `json:"path"`
	Value string `json:"value"`
}

Patch struct represent the struct used to patch the cstorvolumeconfig object
