#### Detrás de un Proxy de Terminación TLS

Si estás ejecutando tu contenedor detrás de un Proxy de Terminación TLS (load balancer) como Nginx o Traefik, añade la opción `--proxy-headers`, esto le dirá a Uvicorn (a través de la CLI de FastAPI) que confíe en los headers enviados por ese proxy indicando que la aplicación se está ejecutando detrás de HTTPS, etc.

```Dockerfile

        if (obj != null
            && Proxy.isProxyClass(obj.getClass())
            && Proxy.getInvocationHandler(obj) instanceof TypeVariableInvocationHandler) {
          TypeVariableInvocationHandler typeVariableInvocationHandler =
              (TypeVariableInvocationHandler) Proxy.getInvocationHandler(obj);
          TypeVariableImpl<?> that = typeVariableInvocationHandler.typeVariableImpl;

#### Por Trás de um Proxy de Terminação TLS

Se você está executando seu contêiner atrás de um Proxy de Terminação TLS (load balancer) como Nginx ou Traefik, adicione a opção `--proxy-headers`, isso fará com que o Uvicorn confie nos cabeçalhos enviados por esse proxy, informando que o aplicativo está sendo executado atrás do HTTPS, etc.

```Dockerfile
CMD ["uvicorn", "app.main:app", "--proxy-headers", "--host", "0.0.0.0", "--port", "80"]

    default Proxy getHttpProxy() {
        Proxy proxy = (Proxy) propMap.get(HTML_PROXY);
        if (proxy == null) {
            if (StringUtil.isNotBlank(getHttpProxyHost()) && getHttpProxyPortAsInteger() != null) {
                final SocketAddress addr = new InetSocketAddress(getHttpProxyHost(), getHttpProxyPortAsInteger());
                proxy = new Proxy(Type.HTTP, addr);
