Types

type ConfigMapControl

type ConfigMapControl struct {
	ConfigMapControlInterface
	// contains filtered or unexported fields
}

func (*ConfigMapControl) DeleteConfigMap

func (rcmc *ConfigMapControl) DeleteConfigMap(ndb *v1alpha1.Ndb) error

func (*ConfigMapControl) EnsureConfigMap

func (rcmc *ConfigMapControl) EnsureConfigMap(ndb *v1alpha1.Ndb) (*corev1.ConfigMap, error)

func (*ConfigMapControl) ExtractConfig

func (rcmc *ConfigMapControl) ExtractConfig(cm *corev1.ConfigMap) (string, error)

func (*ConfigMapControl) PatchConfigMap

func (rcmc *ConfigMapControl) PatchConfigMap(ndb *v1alpha1.Ndb) (*corev1.ConfigMap, error)

Patch existing config map with new configuration data generated from ndb CRD object

type ConfigMapControlInterface

type ConfigMapControlInterface interface {
	EnsureConfigMap(ndb *v1alpha1.Ndb) (*corev1.ConfigMap, error)
	PatchConfigMap(ndb *v1alpha1.Ndb) (*corev1.ConfigMap, error)
	ExtractConfig(cm *corev1.ConfigMap) (string, error)
	DeleteConfigMap(ndb *v1alpha1.Ndb) error
}

func NewConfigMapControl

func NewConfigMapControl(client kubernetes.Interface,
	configMapInformer coreinformers.ConfigMapInformer) ConfigMapControlInterface

NewConfigMapControl creates a new ConfigMapControl

type Controller

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

Controller is the main controller implementation for Ndb resources

func NewController

func NewController(
	kubeclientset kubernetes.Interface,
	ndbclientset clientset.Interface,
	statefulSetInformer appsinformers.StatefulSetInformer,
	serviceInformer coreinformers.ServiceInformer,
	podInformer coreinformers.PodInformer,
	configMapInformer coreinformers.ConfigMapInformer,
	ndbInformer informers.NdbInformer) *Controller

NewController returns a new Ndb controller

func (*Controller) Run

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

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.

type StatefulSetControlInterface

type StatefulSetControlInterface interface {
	EnsureStatefulSet(ndb *v1alpha1.Ndb) (*apps.StatefulSet, error)
	GetStatefulSet(ndb *v1alpha1.Ndb) (*apps.StatefulSet, error)
	Patch(ndb *v1alpha1.Ndb, old *apps.StatefulSet) (*apps.StatefulSet, error)
}

func NewRealStatefulSetControl

func NewRealStatefulSetControl(client kubernetes.Interface, statefulSetLister appslisters.StatefulSetLister) StatefulSetControlInterface

NewRealStatefulSetControl creates a concrete implementation of the StatefulSetControlInterface.
