Continuing the transition from Endpoints to EndpointSlices
- Since the introduction of EndpointSlices, the Endpoints API in Kubernetes has become obsolete for new features.
- As of Kubernetes 1.33, the Endpoints API is officially deprecated, and users are encouraged to switch to EndpointSlices.
- The plan is to change Kubernetes Conformance criteria to eliminate the need for running the Endpoints controller in modern clusters.
- Users with workloads or scripts still using the Endpoints API should start migrating to EndpointSlices.
- EndpointSlice API allows Services to have multiple EndpointSlices associated with them, supporting features like dual-stack networking.
- EndpointSlices are used to represent endpoints of a single IP family, handle changes in port configurations, and manage a large number of endpoints efficiently.
- When fetching EndpointSlices, users should use labels to associate them with the corresponding Service rather than by name.
- Migrating to EndpointSlices involves updating code to fetch and process EndpointSlices instead of Endpoints.
- For generating EndpointSlices, a new YAML format is required, including explicit address types and conditions for each endpoint.
- EndpointSlices offer new features like topology hints and terminating endpoints, enhancing functionality beyond the Endpoints API.
