- Kubeadm: add support for `127.0.0.1` as advertise address. kubeadm will automatically replace this value with matching global unicast IP address on the loopback interface. ([#83475](https://github.com/kubernetes/kubernetes/pull/83475), [@fabriziopandini](https://github.com/fabriziopandini))

# Optional ENV vars

#   MAVEN_OPTS - parameters passed to the Java VM when running Maven

    - Copy the OAuth Client Key as the value for `<CLIENT_ID>`.
    - Copy the OAuth Client Secret as the value for `<CLIENT_SECRET>`.
  - By default, `<IS_HOST>` is localhost. However, if using a public IP, the respective IP address or domain needs to be specified.
  - By default, `<IS_HTTPS_PORT>` has been set to 9443. However, if the port offset has been incremented by n, the default port value needs to be incremented by n.

Request

```

Então, crie um arquivo `traefik.toml` com:

```TOML hl_lines="3"
[entryPoints]
  [entryPoints.http]
    address = ":9999"

[providers]
  [providers.file]
    filename = "routes.toml"
```

Isso diz ao Traefik para escutar na porta 9999 e usar outro arquivo `routes.toml`.

/// tip | Dica

These headers preserve information about the original request that would otherwise be lost:

* **X-Forwarded-For**: The original client's IP address
* **X-Forwarded-Proto**: The original protocol (`https`)
* **X-Forwarded-Host**: The original host (`mysuperapp.com`)

### Choosing between application and network interceptors

Each interceptor chain has relative merits.

**Application interceptors**

            // use a KDC of our choice.
