envoy 配置解析错误 INVALID_ARGUMENT:Unexpected token

Question

我试图从 envoy 文档中设置一个基本的 envoy 代理（使用 Docker），但我不断收到如下解析错误：

如您所见，这是 JSON 到 Proto 的解析错误，但我不知道我在哪里偏离了网站上的文档。除非文档已过时！下面是我的 envoy.yml 文件：

admin:
  access_log_path: /tmp/admin_access.log
  address:
    socket_address: { address: 127.0.0.1, port_value: 9901 }

              routes:
              - match: { prefix: "/" }
                route: { cluster: some_service }

                address: 127.0.0.1
                port_value: 1234

这是我的 docker-compose 文件的特使部分：

 envoy:
    image: envoyproxy/envoy:v1.11.1
    command: /usr/local/bin/envoy -c /etc/envoy/envoy.yml -l debug --service-cluster proxy
    container_name: envoy

    volumes:

      - mongo-cluster

发现了问题，我很傻，我知道我一定很傻，但直到我发布问题才弄明白，哈哈。

问题与我的 yaml 文件扩展名有关。我使用的是 .YML 而不是 .YAML 我不知道为什么 VS Code 会识别出让我反感的扩展。
