TODO: This document was manually maintained so might be incomplete. The
|
||
|
|
automation effort is tracked in
|
||
|
|
https://github.com/kubernetes/client-go/issues/234.
|
||
|
|
|
||
|
|
Changes in `k8s.io/api` and `k8s.io/apimachinery` are mentioned here
|
||
|
|
because `k8s.io/client-go` depends on them.

**Breaking changes:**
|
||
|
|
|
||
|
|
* Moved pkg/api and pkg/apis to [k8s.io/api](https://github.com/kubernetes/api). Other kubernetes repositories also import types from there, so they are composable with client-go.
|
||
|
|
|
||
|
|
* Removed helper functions in pkg/api and pkg/apis. They are planned to be exported in other repos. The issue is tracked [here](https://github.com/kubernetes/kubernetes/issues/48209#issuecomment-314537745). During the transition, you'll have to copy the helper functions to your projects.
|
||
|
|
|
||
|
|
* The discovery client now fetches the protobuf encoded OpenAPI schema and returns `openapi_v2.Document`
|
||

* [https://github.com/kubernetes/kubernetes/pull/46803](https://github.com/kubernetes/kubernetes/pull/46803)
|
||
|
|
|
||
|
|
* Enforced explicit references to API group client interfaces in clientsets to avoid ambiguity.

|
||
|
|
|
||
|
|
* The generic RESTClient type (`k8s.io/client-go/rest`) no longer exposes `LabelSelectorParam` or `FieldSelectorParam` methods - use `VersionedParams` with `metav1.ListOptions` instead. The `UintParam` method has been removed. The `timeout` parameter will no longer cause an error when using `Param()`.

|
|
Bug fixes:
|
||
|
|
* Use OS-specific libs when computing client User-Agent in kubectl, etc. (https://github.com/kubernetes/kubernetes/pull/44423)
|
||
|
|
* kubectl commands run inside a pod using a kubeconfig file now use the namespace specified in the kubeconfig file, instead of using the pod namespace. If no kubeconfig file is used, or the kubeconfig does not specify a namespace, the pod namespace is still used as a fallback. (https://github.com/kubernetes/kubernetes/pull/44570)
|
||
|
|
* Restored the ability of kubectl running inside a pod to consume resource files specifying a different namespace than the one the pod is running in. (https://github.com/kubernetes/kubernetes/pull/44862)
