azure - Traefik 与 Service Fabric — 无法连接到 Service Fabric 服务器

Question

我已使用以下配置在我的 Azure Service Fabric 集群上部署了 Traefik:

# Enable Service Fabric configuration backend
[servicefabric]

# Service Fabric Management Endpoint
clustermanagementurl = "https://localhost:19080"

# Service Fabric Management Endpoint API Version
apiversion = "3.0"

insecureSkipVerify = true

但是，当打开 Traefik 仪表板时，我看到一个空屏幕，因为它无法映射我的所有 Fabric 应用程序。

查看我的一台虚拟机上的 Traefik 日志，我反复看到此错误:

level=error msg="failed to connect to Service Fabric server Get https://localhost:19080/Applications/?api-version=3.0: x509: certificate is valid for <hidden>.eastus.cloudapp.azure.com, not localhost on https://localhost:19080/Applications/?api-version=3.0"

我的 Azure Service Fabric 群集具有由受信任的 CA 签名的 SSL 证书:

如何解决这个问题？

如果有帮助，这是 Traefik 加载的配置(根据日志):

有人建议使用我的集群的远程地址而不是 localhost ，这样做会导致不同的错误:

Provider connection error: failed to connect to Service Fabric server Get https://<hidden>.eastus.cloudapp.azure.com:19080/Applications/?api-version=3.0: stream error: stream ID 1; HTTP_1_1_REQUIRED on https://<hidden>.eastus.cloudapp.azure.com:19080/Applications/?api-version=3.0; retrying in 656.765021ms

Answer 1

感谢迭戈的评论(在我的问题下)，我通过添加以下内容成功解决了这个问题。

出了什么问题？

1. 我的 SF 集群是安全的，需要客户端证书才能登录 - Traefik TOML 文件中未指定该证书。 (希望记录的错误能提供更多信息)

2. 查看 Traefik 日志，特别是 SF 部分(查找以 Starting provider *servicefabric.Provider 开头的跟踪:

   "Watch": false,
   "Filename": "",
   "Constraints": null,
   "Trace": false,
   "DebugLogGeneratedTemplate": false,
   "ClusterManagementURL": "https://localhost:19080",
   "APIVersion": "3.0",
   "UseCertificateAuth": false,      <-------- Important
   "ClientCertFilePath": "",         <-------- Important
   "ClientCertKeyFilePath": "",      <-------- Important
   "InsecureSkipVerify": false
   

   • UseCertificateAuth -- 表示Traefik查询集群管理端点时是否使用客户端证书。
   • ClientCertFilePath -- 客户端证书公钥文件路径。
   • ClientCertKeyFilePath -- 客户端证书私钥文件路径。

(两个路径都应该相对于 traefik.exe )

不安全SkipVerify

Traefik 的 SF 配置(上图)包括一个名为 InsecureSkipVerify 的设置。

• InsecureSkipVerify -- 如果设置为false ，那么 Traefik 将拒绝与管理端点的连接，除非使用的 SSL 证书由受信任的 CA 签名。
• 如果证书是为远程地址签名的，而 Traefik 使用 https://localhost，这可能会出现问题作为集群的端点——然后 Traefik 会打印类似如下的错误:

failed to connect to Service Fabric server Get https://localhost:19080/Applications/?api-version=3.0: x509: certificate is valid for .eastus.cloudapp.azure.com, not localhost

要克服这个问题，您可以:

• 设置InsecureSkipVerify = true并重新部署
• 将管理端点设置为远程地址: clustermanagementurl = "https://<hidden>.eastus.cloudapp.azure.com:19080"

再次感谢Diego给我的提示，让我理解并分享上述解释。
