apicurio-studio 🚀 - Kubernetes 上的 API 编辑丢失连接

我假设#813 中的信息对您没有帮助？这看起来像同样的问题。也许@0x218可以详细说明适用于他们安装的更改？或者@t-rap 有什么想法？我的 Kubernetes 专业知识非常有限。

EricWittmann 于 2020-06-07

是的，我尝试在建议的 Nginx Ingress @ 0x218 中应用版本、升级和连接标头。然而，我无法连接到网络套接字。

我可以提供任何日志以进一步了解问题吗？

cemnura 于 2020-06-08

如果您可以从 -ws pod 提供“完整”浏览器控制台输出和服务器日志，那可能会有所帮助。

cemnura 于 2020-06-10

伙计，我不知道可能出了什么问题。我要请您确保 -ws 和 -api pod 连接到同一个数据库。如果不是，您会收到连接错误，但在这种情况下，-ws pod 日志会显示错误，并且您不会收到 404 我不认为。

看来这一定是某种 Ingress 问题，我对 k8s 的了解还不够，无法提供帮助！ :(

EricWittmann 于 2020-06-10

我还尝试通过 NodePort 直接公开 ws pod。然而我仍然没有成功。

我要再试一次。增加日志级别有帮助吗？

cemnura 于 2020-06-10

它不会受伤。 -ws 日志中有一些关于身份验证的内容我不太了解，因为 -ws 组件没有启用任何身份验证。也许增加日志级别会更清楚地说明这一点。

EricWittmann 于 2020-06-10

您认为我应该将日志级别提高到什么级别？

cemnura 于 2020-06-10

可能从 DEBUG 开始，看看会发生什么。 :)

EricWittmann 于 2020-06-10

我增加了日志级别以进行调试。然而，没有有益的日志。

您包含的服务器日志实际上是-ui pod 的日志，而不是-ws pod 的日志。

EricWittmann 于 2020-06-15

错误码1006表示浏览器异常关闭了web socket。 :( 遗憾的是，浏览器很可能不会给你一个理由。这里有一些信息：

https://stackoverflow.com/questions/19304157/getting-the-reason-why-websockets-closed-with-close-code-1006

您也许可以尝试找到某种 websocket 测试工具并尝试使用它。它可能会为您提供一些我们可以使用的诊断信息。

EricWittmann 于 2020-06-15

使用以下命令检索的日志

kubectl logs apicurio-studio-ws-7c458cf8d8-cgscc

是否有我可以搜索的特定日志？

cemnura 于 2020-06-15

您对测试 Web 套接字有什么建议吗？

cemnura 于 2020-06-15

我找到了一种通过https://websocket.org/echo.html测试网络套接字的方法。

我将 ws 连接代码复制到我的计算机上。我应该发送什么信息？

cemnura 于 2020-06-15

这真的很奇怪，因为您在上面发布的输出清楚地显示了 keycloak auth redirect 和其他与 keycloak 相关的输出，以及对config.js和version.js的请求——这些都是 UI 所做的事情。 websocket 组件根本不包含 Keycloak。您能否从所有三个pod 中获取日志输出？那会很有趣。也许实际上是吊舱有问题！

至于测试网络套接字。只需尝试连接，看看会发生什么。如果它工作正常，你应该得到这样的东西：

如果您的连接在“连接”阶段被破坏，那么初始连接可能会失败。

EricWittmann 于 2020-06-15

我通过复制 websocket.org 上提供的代码来测试 websocket，并将其作为 websocket.html 保存在我的硬盘上，以测试我本地网络上的 ws pod。不幸的是，我无法连接到本地网络中的 ws。但是，我能够连接公共 websocket
wss://studio-ws.apicur.io/designs 。因此，我认为 websocket 测试是可行的。

我提供了附件中的所有日志

kubectl 记录 apicurio-studio-ui-5c6f5df485-lcdxp > apicurio-studio-ui.log
kubectl 记录 apicurio-studio-ws-77dc7f7b87-57dcs > apicurio-studio-ws.log
kubectl 记录 apicurio-studio-api-79d9d799cb-mgsmx > apicurio-studio-api.log

apicurio-studio-api.log
apicurio-studio-ui.log
apicurio-studio-ws.log

我终于让它工作了！我直接通过 NodePort 暴露了ws pod。我现在确定问题出在入口配置上。

惊人的！！感谢您推动这一点（不放弃）。很抱歉，我无法提供更多帮助。我的kubernetes知识水平低。您可以发布您需要添加的任何 YAML 配置以使其正常工作吗？我们最终将为 Apicurio Studio 创建一个运算符，但我不知道具体何时会发生。

EricWittmann 于 2020-06-16

老实说，我没有进行特定的 yaml 配置。

我创建了一个 NodePort 服务，这意味着 ws pods 8080 端口在随机端口上的机器 IP 上公开。

这就是我创建 NodePort 的方式
kubectl expose deployment apicurio-studio-ws --type NodePort --name test

这给了我一个随机端口 32204，可以通过机器 IP:32204 访问。

kubectl 获取 svc

NAME                           TYPE        CLUSTER-IP       EXTERNAL-IP   PORT(S)          AGE
test                           NodePort    10.152.183.2     <none>        8080:32204/TCP   10h

我仍然认为入口 nginx 应该是暴露 websocket 的首选方式，因为 NodePort 端口是随机的，不能在apicurio-configmap.yaml中预先配置。

在我的情况下是

apicurio-configmap.yaml

apiVersion: v1
kind: ConfigMap
metadata:
  name: apicurio-configmap
data:
  apicurio-db-connection-url: jdbc:mysql://apicuriodb:3306/apicuriodb

  apicurio-ui-feature-share-with-everyone: "true"

cemnura 于 2020-06-16

好的很有趣。不知道为什么 nginx 方法不适合你。 :(但很高兴你有一些工作！

EricWittmann 于 2020-06-17

我找到了一种通过入口暴露 ws pod 的方法。此解决方案更具可配置性。

Screen Shot 2020-06-19 at 1 40 21 AM

在这个解决方案中，我通过入口为 WS pod 创建了一个单独的 URL。

我会提供一个 PR 进行评估。

嘿，很抱歉迟到了。

@cemnura您使用的是什么入口，在哪个版本中？

nginx-ingress-controller 已经有很多修复和更改，如果你使用它的话。

奇怪的一件事是 websocket 行为，尤其是当您尝试在 http/https 之间切换时。

@EricWittmann如果您愿意，我可以测试补丁版本是否有效（nginx-ingress-version 更新到最新版本）

cemnura 于 2020-06-22

非常感谢@cemnura
你能测试一下我做的叉子（见下文）吗？提前（再次）感谢:)

我使用 ingress-nginx-controller 版本 0.24.1 和 apicurio-studio 0.2.44.Final 在https://github.com/t-rap/apicurio-studio-981/上测试了配置
我将子路径“/designs”添加到入口 apicurio-studio-ws，因为这是一个需要由 ws 处理的子路径。

我将在 ingress-controller 0.25.1 和 apicurio-studio 0.2.46 上运行一些测试。Final 可能在周末。
由于入口控制器由 kubernetes 维护，因此需要识别大量更改。

我还删除了配置片段，因为它不再需要了（我的错，duh）

完成后我会提供更新。

我能够使用提供的 Kubernetes 清单 @t-rap 在与ui pod 相同的 url 上公开ws pod。

但是，有一些小的变化。

我将 ws pod 入口名称更改为apicurio-studio-ws

https://github.com/Apicurio/apicurio-studio/blob/17a8e6bc21cae5a90aebb1a7a0e64350aeb30f57/distro/kubernetes/apicurio-studio-ingresses.yaml#L38 -L41

删除了 $ apicurio-configmap.yaml中apicurio-ui-editing-url键的/ws后缀

https://github.com/Apicurio/apicurio-studio/blob/17a8e6bc21cae5a90aebb1a7a0e64350aeb30f57/distro/kubernetes/apicurio-configmap.yaml#L9

删除了 apicurio-studio-ingresses.yaml 中 ingress 配置中的apicurio-studio-ingresses.yaml /ws路径

这是我的配置
