An <a href="https://en.wikipedia.org/wiki/Environment_variable" class="external-link" target="_blank">environment variable</a> (also known as "env var") is a variable that lives outside of the Python code, in the operating system, and could be read by your Python code (or by other programs as well).

You can create and use environment variables in the shell, without needing Python:

=== "Linux, macOS, Windows Bash"

    <div class="termy">

  // Ex. "ext4", "xfs". Implicitly inferred to be "ext4" if unspecified.
  optional string fsType = 2;

  // readOnly defaults to false (read/write). ReadOnly here will force
  // the ReadOnly setting in VolumeMounts.
  // +optional
  optional bool readOnly = 3;
}

// Preconditions must be fulfilled before an operation (update, delete, etc.) is carried out.

### 3.1 Use `certgen` to Generate a Certificate

Download [`certgen`](https://github.com/minio/certgen/releases/latest) for your specific operating system and platform.

`certgen` is a simple *Go* tool to generate self-signed certificates, and provides SAN certificates with DNS and IP entries:

```sh
./certgen -host "10.10.0.3,10.10.0.4,10.10.0.5"
```
