- sidecar interception is enabled if:
    - "istio-init" container is not present in the pod.
    - istio-proxy container exists and
        - does not have DISABLE_ENVOY environment variable (which triggers proxyless mode)
        - has a istio-proxy container, with first 2 args "proxy" and "sidecar" - or less then 2 args, or first arg not proxy.
        - "sidecar.istio.io/inject" is not false
        - "sidecar.istio.io/status" exists

Como temos um proxy com um prefixo de caminho de `/api/v1` para nossa aplicação, o frontend precisa buscar o OpenAPI schema em `/api/v1/openapi.json`.

```mermaid
graph LR

browser("Browser")
proxy["Proxy on http://0.0.0.0:9999/api/v1/app"]
server["Server on http://127.0.0.1:8000/app"]

browser --> proxy
proxy --> server
```

/// tip | "Dica"

Da wir für unsere Anwendung einen Proxy mit dem Pfadpräfix `/api/v1` haben, muss das Frontend das OpenAPI-Schema unter `/api/v1/openapi.json` abrufen.

```mermaid
graph LR

browser("Browser")
proxy["Proxy auf http://0.0.0.0:9999/api/v1/app"]
server["Server auf http://127.0.0.1:8000/app"]

browser --> proxy
proxy --> server
```

/// tip | "Tipp"

Because we have a proxy with a path prefix of `/api/v1` for our app, the frontend needs to fetch the OpenAPI schema at `/api/v1/openapi.json`.

```mermaid
graph LR

browser("Browser")
proxy["Proxy on http://0.0.0.0:9999/api/v1/app"]
server["Server on http://127.0.0.1:8000/app"]

browser --> proxy
proxy --> server
```

/// tip

    private const val PROXY_A_HOST = "proxya"
    private val proxyA =
      Proxy(
        Proxy.Type.HTTP,
        InetSocketAddress.createUnresolved(PROXY_A_HOST, PROXY_A_PORT),
      )

    private const val PROXY_B_PORT = 1002
    private const val PROXY_B_HOST = "proxyb"
    private val proxyB =
      Proxy(
        Proxy.Type.HTTP,

这是因为应用使用了以 `/api/v1` 为路径前缀的代理，前端要从 `/api/v1/openapi.json`  中提取 OpenAPI 概图。

```mermaid
graph LR

browser("Browser")
proxy["Proxy on http://0.0.0.0:9999/api/v1/app"]
server["Server on http://127.0.0.1:8000/app"]

browser --> proxy
proxy --> server
```

/// tip | "提示"

IP `0.0.0.0` 常用于指程序监听本机或服务器上的所有有效 IP。

///

API 文档还需要 OpenAPI 概图声明 API `server` 位于 `/api/v1`（使用代理时的 URL）。例如：

↩️ 👥 ✔️ 🗳 ⏮️ ➡ 🔡 `/api/v1` 👆 📱, 🕸 💪 ☕ 🗄 🔗 `/api/v1/openapi.json`.

graph LR

browser("Browser")
proxy["Proxy on http://0.0.0.0:9999/api/v1/app"]
server["Server on http://127.0.0.1:8000/app"]

browser --> proxy
proxy --> server
