// EnvVar represents an environment variable present in a Container.
message EnvVar {
  // Name of the environment variable. Must be a C_IDENTIFIER.
  optional string name = 1;

  // Variable references $(VAR_NAME) are expanded

  // any service environment variables. If a variable cannot be resolved,

   - Server-side feature gate: PortForwardWebsocket
   - Client-side (kubectl) feature gate: PORT_FORWARD_WEBSOCKETS environment variable
   - To turn off PortForward over WebSockets for kubectl, the environment variable feature gate must be explicitly set - PORT_FORWARD_WEBSOCKETS=false ([#125528](https://github.com/kubernetes/kubernetes/pull/125528), [@seans3](https://github.com/seans3)) [SIG API Machinery and CLI]

    * If you are running E2E tests which require SSH keys and you utilize environment variables to override their location, you may need to modify the environment variable set. On all providers the environment variable override can now be either an absolute path to the key or a relative path (relative to ~/.ssh). Specifically the changes are:

- Added authorization check support to the CEL expressions of ValidatingAdmissionPolicy via a `authorizer`

### ConfigMap
* Volumes and environment variables populated from ConfigMap and Secret objects can now tolerate the named source object or specific keys being missing, by adding `optional: true` to the volume or environment variable source specifications. ([#39981](https://github.com/kubernetes/kubernetes/pull/39981), [@fraenkel](https://github.com/fraenkel))

* `hack/local-up-cluster.sh` now enables the Node authorizer by default. Authorization modes can be overridden with the `AUTHORIZATION_MODE` environment variable, and the `ENABLE_RBAC` environment variable is no longer used. ([#49812](https://github.com/kubernetes/kubernetes/pull/49812), [@liggitt](https://github.com/liggitt))

* CUSTOM_KUBE_DASHBOARD_BANNER environment variable will be used to populate notification banner in Kubernetes Dashboard add-on. ([#60639](https://github.com/kubernetes/kubernetes/pull/60639), [@konryd](https://github.com/konryd))

* 🔨 Add script to generate variants of files. PR [#12405](https://github.com/fastapi/fastapi/pull/12405) by [@tiangolo](https://github.com/tiangolo).
* 🔧 Add speakeasy-api to `sponsors_badge.yml`. PR [#12404](https://github.com/fastapi/fastapi/pull/12404) by [@tiangolo](https://github.com/tiangolo).

- The `kubectl plugin list` command now displays discovered plugin paths in the same order as they are found in a user's PATH variable. ([#70443](https://github.com/kubernetes/kubernetes/pull/70443), [@juanvallejo](https://github.com/juanvallejo))
