Package crdclient provides an implementation of the config store and cache using Kubernetes Custom Resources and the informer framework from Kubernetes

This code relies heavily on code generation for performance reasons; to implement the Istio store interface, we need to take dynamic inputs. Using the dynamic informers results in poor performance, as the cache will store unstructured objects which need to be marshaled on each Get/List call. Using istio/client-go directly will cache objects marshaled, allowing us to have cheap Get/List calls, at the expense of some code gen.

func New ¶ Uses

func New(client kube.Client, revision, domainSuffix string) (model.ConfigStoreCache, error)

func NewForSchemas ¶ Uses

func NewForSchemas(client kube.Client, revision, domainSuffix string, schemas collection.Schemas) (model.ConfigStoreCache, error)

func TranslateObject ¶ Uses

func TranslateObject(r runtime.Object, gvk config.GroupVersionKind, domainSuffix string) *config.Config

type Client ¶ Uses

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

Client is a client for Istio CRDs, implementing config store cache This is used for CRUD operators on Istio configuration, as well as handling of events on config changes

func (*Client) Create ¶ Uses

func (cl *Client) Create(cfg config.Config) (string, error)

Create implements store interface

func (*Client) Delete ¶ Uses

func (cl *Client) Delete(typ config.GroupVersionKind, name, namespace string, resourceVersion *string) error

Delete implements store interface `resourceVersion` must be matched before deletion is carried out. If not possible, a 409 Conflict status will be

func (*Client) Get ¶ Uses

func (cl *Client) Get(typ config.GroupVersionKind, name, namespace string) *config.Config

Get implements store interface

func (*Client) HasSynced ¶ Uses

func (cl *Client) HasSynced() bool

func (*Client) List ¶ Uses

func (cl *Client) List(kind config.GroupVersionKind, namespace string) ([]config.Config, error)

List implements store interface

func (*Client) Patch ¶ Uses

func (cl *Client) Patch(orig config.Config, patchFn config.PatchFunc) (string, error)

Patch applies only the modifications made in the PatchFunc rather than doing a full replace. Useful to avoid read-modify-write conflicts when there are many concurrent-writers to the same resource.

func (*Client) RegisterEventHandler ¶ Uses

func (cl *Client) RegisterEventHandler(kind config.GroupVersionKind, handler func(config.Config, config.Config, model.Event))

func (*Client) Run ¶ Uses

func (cl *Client) Run(stop <-chan struct{})

Run the queue and all informers. Callers should wait for HasSynced() before depending on results.

func (*Client) Schemas ¶ Uses

func (cl *Client) Schemas() collection.Schemas

Schemas for the store

func (*Client) Update ¶ Uses

func (cl *Client) Update(cfg config.Config) (string, error)

Update implements store interface

func (*Client) UpdateStatus ¶ Uses

func (cl *Client) UpdateStatus(cfg config.Config) (string, error)
