## Known Issues

### Summary API in kubelet doesn't have accelerator metrics

- Azure VMSS/VMSSVM clients now suppress requests on throttling ([#86740](https://github.com/kubernetes/kubernetes/pull/86740), [@feiskyer](https://github.com/feiskyer)) [SIG Cloud Provider]
- Azure cloud provider cache TTL is configurable, list of the azure cloud provider is as following:
  - "availabilitySetNodesCacheTTLInSeconds"

apiServerExtraArgs:
  cloud-provider: "{cloud}"
  cloud-config: "{cloud-config-path}"
apiServerExtraVolumes:
- name: cloud
  hostPath: "{cloud-config-path}"
  mountPath: "{cloud-config-path}"
controllerManagerExtraArgs:
  cloud-provider: "{cloud}"
  cloud-config: "{cloud-config-path}"
controllerManagerExtraVolumes:
- name: cloud
  hostPath: "{cloud-config-path}"

- Azure: check the nil error before invoke err.Error() ([#96623](https://github.com/kubernetes/kubernetes/pull/96623), [@nilo19](https://github.com/nilo19)) [SIG Cloud Provider]

* Authentication information for OpenStack cloud provider can now be specified as environment variables. When we convert the OpenStack cloud provider to run in an external process, we can now use the kubernetes Secrets capability to inject the OS_* variables. This way we can specify the cloud configuration as a configmap, and specify secrets for the userid/password information. The configmap is mounted as a file, and...

- The cloud config for Azure cloud provider can now be initialized from Kubernetes secret azure-cloud-provider in kube-system namespace
    - the secret is a serialized version of `azure.json` file with key cloud-config. And the secret name is azure-cloud-provider.

  - example manifests for the kube-apiserver, kube-controller-manager, kube-schedule, kubelet, and the cloud-controller-manager
  - labels/annotations that are consumed by any cloud specific controllers

In addition to the above, SIG Cloud Provider has been focusing on a long running effort to remove cloud provider code from kubernetes/kubernetes.

- Fix: initial delay in mounting azure disk & file ([#93052](https://github.com/kubernetes/kubernetes/pull/93052), [@andyzhangx](https://github.com/andyzhangx)) [SIG Cloud Provider and Storage]
- Fixed a performance issue applying json patches to deeply nested objects ([#93813](https://github.com/kubernetes/kubernetes/pull/93813), [@liggitt](https://github.com/liggitt)) [SIG API Machinery, CLI, Cloud Provider and Cluster Lifecycle]

* Deprecate auto detecting cloud providers in kubelet. Auto detecting cloud providers go against the initiative for out-of-tree cloud providers as we'll now depend on cAdvisor integrations with cloud providers instead of the core repo. In the near future, `--cloud-provider` for kubelet will either be an empty string or `external`.  ([#51312](https://github.com/kubernetes/kubernetes/pull/51312),...
