Functions

func NewKubeCache added in v1.64.0 

func NewKubeCache(kialiClient kubernetes.ClientInterface, cfg config.Config, refreshHandler RegistryRefreshHandler, namespaceSeedList ...string) (*kubeCache, error)

Starts all informers. These run until context is cancelled.

Types

type CachingClient added in v1.62.0 

type CachingClient struct {
	kubernetes.ClientInterface
	// contains filtered or unexported fields
}

CachingClient is a wrapper around a ClientInterface that adds caching. If the object is cached then it is read from the cache. Not all object types are cached. When an object is created, updated, or deleted, then the cache is refreshed and updated.

func NewCachingClient added in v1.62.0 

func NewCachingClient(cache KialiCache, client kubernetes.ClientInterface) *CachingClient

NewCachingClient creates a new CachingClient out of a cache and a client.

func (*CachingClient) GetConfigMap added in v1.62.0 

func (cc *CachingClient) GetConfigMap(namespace, name string) (*core_v1.ConfigMap, error)

func (cc *CachingClient) GetDeployment(namespace string, name string) (*apps_v1.Deployment, error)

func (*CachingClient) GetDeployments added in v1.62.0 

func (cc *CachingClient) GetDeployments(namespace string) ([]apps_v1.Deployment, error)

type KialiCache 

type KialiCache interface {
	GetKubeCaches() map[string]KubeCache

	// Embedded for backward compatibility for business methods that just use one cluster.
	// All business methods should eventually use the multi-cluster cache.
	KubeCache
	NamespacesCache
	ProxyStatusCache
	RegistryStatusCache
}

KialiCache stores both kube objects and non-kube related data such as pods' proxy status. It is exclusively used by the business layer where it's expected to be a singleton. This business layer cache needs access to all the kiali service account has access to so it uses the kiali service account token instead of a user token. Access to the objects returned by the cache should be filtered/restricted to the user's token access but the cache returns objects without any filtering or restrictions.

func FakeGatewaysKialiCache added in v1.45.0
