Theoretically, the apiserver could be told to advertise additional
ports on the kubernetes service, but there was no way to enable this
functionality without forking/vendoring the apiserver code. This was
apparently added in the distant past for OpenShift to use, but it has
not been used in OpenShift since Kubernetes 1.11.
EndpointSlice is always enabled now, so make it non-optional in the
EndpointsAdapter, make all of the test cases pass an EndpointSlice
client, and remove the "EndpointSlices disabled"-specific tests.
By changing makeEndpointsArray() to return both an Endpoints and an
EndpointsSlice, the "initialObjects" and "expectCreate"/"expectUpdate"
fields of (almost) all of the existing unit tests are automatically
switched to be EndpointSlice-aware; instead of having an initial state
with just Endpoints (or nothing), and testing that just the Endpoints
is created/updated correctly, they now have an initial state with both
Endpoints and EndpointSlice (or nothing), and test that both objects
are created/updated correctly.
The handful of existing test cases that used inconsistent Endpoints
and EndpointSlice state have been modified to create the objects
separately.
Consistently verify creates/updates based on the fake client's action
tracking, not based on the return values of the reconciler functions.
(This will also let us check that both Endpoints and EndpointSlices
were created/updated correctly.)
Pass initial state objects to fake.NewSimpleClientSet() rather than
calling Create() by hand.
(This will make it easier to have an initial state that is a mix of
Endpoints and EndpointSlices later on.)
When the endpoint reconcilers got split out of pkg/controlplane,
GetMasterServiceUpdateIfNeeded() got moved to
pkg/controlplane/reconcilers, even though it needs to be kept in sync
with CreateOrUpdateMasterServiceIfNeeded() which stayed in
pkg/controlplane. (And everything else in pkg/controlplane/reconcilers
is about the Endpoints not the Service anyway.) So move it back.
On the flip side, the implementation of masterCountEndpointReconciler
got moved to pkg/controlplane/reconcilers, but its unit tests didn't.
So belatedly fix that.
* Introduce networking/v1alpha1 api, ClusterCIDRConfig type
Introduce networking/v1alpha1 api group.
Add `ClusterCIDRConfig` type to networking/v1alpha1 api group, this type
will enable the NodeIPAM controller to support multiple ClusterCIDRs.
* Change ClusterCIDRConfig.NodeSelector type in api
* Fix review comments for API
* Update ClusterCIDRConfig API Spec
Introduce PerNodeHostBits field, remove PerNodeMaskSize
This commit includes all the changes needed for APIServer. Instead of modifying the existing signatures for the methods which either generate or return stopChannel, we generate a context from the channel and use the generated context to be passed to the controllers which are started in APIServer. This ensures we don't have to touch APIServer dependencies.
The apiserver owns and manages the kubernetes.default service.
It has 3 different options to reconcile the endpoints that belong to
that service:
- None: endpoints are handled by an external party.
- MasterCount: legacy, it reconciles based on the endpoints generated
and a flag specifying the number of master on the cluster.
- Lease: default since 1.11, each apiserver writes a lease in etcd
and renews periodically, the endpoints are generated based on the
existing leases.
It seems that when the default was set for the lease reconciler, the
controlplane code wasn't updated and kept using the master count
reconciler.
This also starts the deprecation of the master count reconciler in
favor of the lease reconciler.
ServerResources function was deprecated and instead ServerGroupsAndResources
function is suggested.
This PR removes ServerResources function and move every place to use ServerGroupsAndResources.
The apiserver may be configured to generate the Service
kubernetes.default and its endpoints addresses.
This service is single-stack, hence, the endpoints and the ClusterIP
must have the same IP family.

use Extraconfig to configure the repair interval
and add an integration test for services finalizers, and
possible races with the services repair loop.
Right now, `_, ok := provider.(Notifier); !ok` can mean one of two
things:
1. The provider does not support notification because the provided
content is static.
2. The implementor of the provider hasn't gotten around to implementing
Notifier yet.
These have very different implications. We should not force consumers of
these interfaces to have to figure out the static of Notifier across
sometimes numerous different implementations. Instead, we should force
implementors to implement Notifier, even if it's a noop.
