Functions

func GetClusterID

func GetClusterID(cluster *k8s_cr.Cluster) string

GetClusterID returns a cluster's ID

func ReadClusters

func ReadClusters(k8s kubernetes.Interface, configMapName string,
	configMapNamespace string, cs *ClusterStore) error

ReadClusters reads multiple clusters from a ConfigMap

func StartSecretController

func StartSecretController(k8s kubernetes.Interface,
	cs *ClusterStore,
	serviceController *aggregate.Controller,
	discoveryService *envoy.DiscoveryService,
	namespace string,
	resyncInterval time.Duration,
	watchedNamespace,
	domainSufix string) error

StartSecretController start k8s controller which will be watching Secret object in a specified namesapce

Types

type ClusterStore

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

ClusterStore is a collection of clusters

func NewClustersStore

func NewClustersStore() *ClusterStore

NewClustersStore initializes data struct to store clusters information

func (*ClusterStore) GetClusterAccessConfig

func (cs *ClusterStore) GetClusterAccessConfig(cluster *k8s_cr.Cluster) *clientcmdapi.Config

GetClusterAccessConfig returns the access config file of a cluster

type Controller

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

Controller is the controller implementation for Secret resources

func NewController

func NewController(
	kubeclientset kubernetes.Interface,
	namespace string,
	cs *ClusterStore,
	serviceController *aggregate.Controller,
	discoveryService *envoy.DiscoveryService,
	resyncInterval time.Duration,
	watchedNamespace string,
	domainSufix string) *Controller

NewController returns a new secret controller

func (*Controller) Run

func (c *Controller) Run(stopCh <-chan struct{})

Run starts the controller until it receves a message over stopCh

type Metadata

type Metadata struct {
	Name, Namespace string
}

Metadata defines a struct used as a key

type RemoteCluster

type RemoteCluster struct {
	Cluster        *k8s_cr.Cluster
	Client         *clientcmdapi.Config
	ClusterStatus  string
	Controller     *kube.Controller
	ControlChannel chan struct{}
}

RemoteCluster defines cluster struct
