Cloud Load Balancing HTTPS 重定向不適用於特定主機

在我的負載平衡器中，我有 6 台主機，在所有主機中，除了一台 HTTPS 重定向運作良好。我嘗試了所有可能的配置，並閱讀了 Google 提供的所有文件（概念、操作指南、參考），例如https://cloud.google.com/load-balancing/docs/https/setting-up-http-https-redirect#setting_up_the_http_load_balancer無濟於事...

讓我發瘋的是，在同一個主機中url-map，有一個主機，其 HTTPS 重定向工作 100%，這是不起作用的主機的「相同」副本。這是我的url-map兩台主機隔離的情況：

defaultUrlRedirect:
  httpsRedirect: true
  redirectResponseCode: MOVED_PERMANENTLY_DEFAULT
  stripQuery: false

hostRules:
 - hosts:
   # I'm not using an actual record for this particular host, the following two are real
 - app.rocketseat.dev
  pathMatcher: path-matcher-staging

我想，也許後端服務/儲存桶配置可能有所不同，但它們也是相同的。

答案1

根據您提供的資訊以及在類似情況下，您可能為 HTTP 到 HTTPS 重新導向配置了一個 URL 對應。然而，您需要建立一個 HTTP URL 映射，其唯一目的是將流量重新導向到您在其中配置 hostRules 和 pathMatchers 的 HTTPS URL 映射。

在這個例子，「web-map-http」的建立只是為了將 HTTP 流量重新導向到 HTTPS URL 映射“web-map-https”，而「web-map-https」是您配置 hostRules 和 pathMatchers 的位置。

Cloud Console 應顯示兩個負載平衡器

為 HTTP 到 HTTPS 重定向和主機規則建立一個 url 映射可能有效，但這不是建議的方法。

答案2

我最終意識到問題不在於主機本身，而是我的 URL 映射中的 HTTPS 重定向僅適用於以下網域：谷歌域名。我嘗試將其餘網域遷移到同一個 DNS 提供者/服務（Google雲端DNS）但重定向仍然不起作用。某種較低層級的 HTTP 重定向或 GCP 和 Google Domains 之間的整合？我不知道，我從來沒有見過這樣的事情。

我再次嘗試遵循 HTTP 到 HTTPS 重定向例子。同樣，它不起作用，如果您按照範例進行操作，則在存取 HTTP URL 時總是會遇到 404 錯誤。

但是，如果您將帶有以下路徑匹配器的主機規則新增至 URL 對應：

defaultUrlRedirect:
  httpsRedirect: true
  redirectResponseCode: MOVED_PERMANENTLY_DEFAULT
  stripQuery: false
hostRules:
- hosts:
  - '*'
  pathMatcher: path-matcher-wildcard
kind: compute#urlMap
name: app-http-url-map
pathMatchers:
- defaultUrlRedirect:
    httpsRedirect: true
    redirectResponseCode: MOVED_PERMANENTLY_DEFAULT
    stripQuery: false
  name: path-matcher-wildcard
selfLink: https://www.googleapis.com/compute/v1/projects/my-project-id/global/urlMaps/app-http-url-map

您的所有流量將被重新導向到 HTTPS。 :)
