无法通过 Envoy (v1.17.0) 将 API 调用转发到各自在 docker-compose (v1.27.4) 中的路由

分类：编程问答

如何解决无法通过 Envoy (v1.17.0) 将 API 调用转发到各自在 docker-compose (v1.27.4) 中的路由

tl;dnr

我无法让我的 docker-compose Envoy API 网关正确转发到引用的服务。

“转发的路由”总是以错误告终：

upstream connect error or disconnect/reset before headers. reset reason: connection termination

我一定是搞砸了一些简单的事情，因为这很难解决。任何额外的帮助将不胜感激。

为篇幅和细节道歉！

大家好，这是我第一次尝试使用 Envoy 作为我的 API 网关，并且似乎无法克服上述错误。基本上，我有两个 .Net 5 服务、标签和文档，它们位于单独的 docker 容器中，它们的端口是公开的。我想使用 Envoy 作为一个简单的 API 网关（还没有 https），只是为了根据简单的路由匹配将流量重定向到适当的服务。

现在，我一直在使用许多在线示例作为实验的基础，所以我不得不在某处出错。任何方向指向将不胜感激。我已验证以下所有内容：

  1. 我可以使用“http://localhost:[portid]”和“http://host.docker.internal:[portid]”直接从我的桌面访问我的网络服务
  2. 从 envoy docker cli 实例，我可以正确解析服务的内部 IP (docker-compose) 地址。
  3. 从 envoy docker cli 实例，我可以curl http://localapp-tags/api/Cats成功。
  4. 在外部，我可以导航到“http://host.docker.internal:10000”并查看 Envoy 主页。
  5. 无论我做什么，我都无法使用例如“http://localhost:10080/t/api/Cats”从外部重定向到我的服务。 （下面的跟踪转储）

我用作参考或在本地运行以将我的应用程序的配置文件[s] 基于的站点：

  1. 特使文档，Static Configuration w/ the Default demo file
  2. 特使文档，Front Proxy 和 Blog Post
  3. 用作指南的参考架构，.Net eShopOnContainers
  4. Hosting Reference
  5. 教程，Build an API Gateway with Envoy and use with .NET Core APIs（很好的资源>）

在谷歌搜索数小时后（要列出太多网站/链接），最具体的建议是将 connection_timeout 从 0.25 秒增加到 30 秒，这对我没有任何影响。因此，虽然我知道似乎有答案（这可能是重复的），但实际上没有其他方法可以解决问题:(

我还尝试在 docker-compose 中创建一个命名网络（例如 Front-Proxy 示例，但这也不起作用！）

同样，如果您有任何其他建议，我们将不胜感激。

如您所见，在我想出自己的 docker-compose 和 envoy 配置文件之前，我经历了许多教程和小步骤。

docker-compose.yaml（为了简洁起见省略了一些部分，也忽略了拼写错误，因为我进行了搜索和替换，可能遗漏了一些东西）

所以，是的，我有点困在这里试图找出我错过/搞砸的东西（但在这两周后我可能只是代码盲）。 envoy.yaml 文件是从参考资料中复制的，所以我只是遗漏了一些明显的东西（希望这不仅仅是 ico 问题！）。

跟踪日志中有一些错误，包括上面的主要错误，但我还没有弄清楚问题（或欣赏/理解跟踪日志）！摘录：

对于任何指点或建议，我们深表歉意并提前致谢。我可以根据需要提供任何缺失的参考文档。

再次感谢！

解决方法

我打算再给它几天时间，但我想我发现了问题......似乎是手指粗，复制和粘贴。

  1. 我删除了上面评论中提到的有问题的空 http2 选项。这在集群中得到了解决：
- name: tags_service
    connect_timeout: 30s
    type: strict_dns
    lb_policy: round_robin
    # http2_protocol_options: {} !remove these lines
    load_assignment:
      cluster_name: tags_service
      endpoints:
      - lb_endpoints:
        - endpoint:
            address:
              socket_address:
                address: localapp-tags
                port_value: 80
  1. 一旦“错误”消失，我只剩下一个普通的空白页和内部 404 错误（通过 curl 看到）......我意识到需要修改路由器指令：
route:
  cluster: tags_service
  auto_host_rewrite: true
  prefix_rewrite: "/"  # add this line so that we remove the /{route}/ from the gw
  idle_timeout: 10s

现在我将返回并重新启用我之前的一些设置，也许会尝试Edge Proxy Settings。至少它现在运行正常，我学到了很多东西。

最好的部分是 SO 在这个过程中扮演的角色。 （这不是讽刺！）在用不同的工作示例跳来跳去几天之后，我当然将一些不正确的东西复制到我的配置中（我猜我需要更多的 RTFM）。发布一个 SO 问题会让人们重新评估所采取的所有步骤和流程，并点燃一点火。

谢谢！
