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 secrets are made available as environment variables. The external controller itself runs as a pod/daemonset. For backward compatibility, we preload all the OS_*...

- the boolean and unset values for the --dry-run flag are deprecated and a value --dry-run=server|client|none will be required in a future version. ([#87580](https://github.com/kubernetes/kubernetes/pull/87580), [@julianvmodesto](https://github.com/julianvmodesto)) [SIG CLI]

*   [alpha] Containerized mount utilities
    *   Allow mount utilities, used to mount volumes, to run inside a container instead of on the host.
*   Bug Fixes
    *   ScaleIO volume plugin is no longer dependent on the drv_cfg binary, so a Kubernetes cluster can easily run a containerized kubelet. ([#54956](https://github.com/kubernetes/kubernetes/pull/54956),[ @vladimirvivien](https://github.com/vladimirvivien))
