## Create and Use Env Vars

You can **create** and use environment variables in the **shell (terminal)**, without needing Python:

//// tab | Linux, macOS, Windows Bash

<div class="termy">

```console
// You could create an env var MY_NAME with
$ export MY_NAME="Wade Wilson"

// Then you could use it with other programs, like

              passwordSecret:
                description: passwordSecret is name of the authentication secret for
                  BGP Peer. the secret must be of type "kubernetes.io/basic-auth",
                  and created in the same namespace as the MetalLB deployment. The
                  password is stored in the secret as the key "password".
                properties:

- Route controller now respects rate limiting to the cloud provider on deletion; previously it was only for create. ([#78581](https://github.com/kubernetes/kubernetes/pull/78581), [@andrewsykim](https://github.com/andrewsykim))
- Removed extra pod creation expectations when daemonset fails to create pods in batches. ([#74856](https://github.com/kubernetes/kubernetes/pull/74856), [@draveness](https://github.com/draveness))
