环境变量（也称为"env var"）是一种存在于 Python 代码之外、存在于操作系统中的变量，可以被您的 Python 代码（或其他程序）读取。

您可以在 shell 中创建和使用环境变量，而无需使用 Python：

//// tab | Linux、macOS、Windows Bash

<div class="termy">

```console
// 您可以创建一个名为 MY_NAME 的环境变量
$ export MY_NAME="Wade Wilson"

// 然后您可以与其他程序一起使用它，例如
$ echo "Hello $MY_NAME"

Hello Wade Wilson
```

</div>

////

//// tab | Windows PowerShell

<div class="termy">

```console

Replication configuration applied successfully to myminio/srcbucket.
```

The replication configuration generated has the following format and can be exported with `mc replicate export` command:

```json
{
  "Role" :"",
  "Rules": [
    {
      "Status": "Enabled",
      "Priority": 1,
      "DeleteMarkerReplication": { "Status": "Disabled" },

MinIO supports two authentication modes for Prometheus either `jwt` or `public`, by default MinIO runs in `jwt` mode. To allow public access without authentication for prometheus metrics set environment as follows.

```
export MINIO_PROMETHEUS_AUTH_TYPE="public"
minio server ~/test
```

* The formerly publicly-available cAdvisor web UI that the kubelet ran on port 4194 by default is now turned off by default. The flag configuring what port to run this UI on `--cadvisor-port` was deprecated in v1.10. Now the default is `--cadvisor-port=0`, in other words, to not run the web server. If you still need to run cAdvisor, the recommended way to run it is via a DaemonSet. Note that the `--cadvisor-port` will be removed in v1.12 ([#63881](https://github.com/kubernetes/kubernetes/pull/63881),...
