nginx - 无法使用 Ingress SubPath 访问 GUI

问题描述

此问题也已发布到 Gitlab 论坛。 https://forum.gitlab.com/t/unable-to-access-the-gui-with-ingress-subpath/32269 我认为即使在 StackOverFlow 上也会被专家阅读，所以我会发布它。请允许重复发布。

我想在 AWS EKS 上构建 GitLab CE 并使用 Ingress 中设置的子路径访问 GUI。如果hostingress 设置为/，则可以正常访问，如果不是/，例如/gitlab无法访问。使用 Nginx 入口控制器。

我该如何解决？

先感谢您。

附上以下内容作为参考信息。

入口 yaml

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: test-ingress
  annotations:
    kubernetes.io/ingress.class: nginx
    nginx.ingress.kubernetes.io/rewrite-target: /$2
spec:
  rules:
    # host:
    - http:
        paths:
        - path: /gitlab(/|$)(.*)
          backend:
            serviceName: gitlab
            servicePort: 12080

这不起作用，但我将rewrite-target设置更改为/并更改path为/Then you can access with GUI。

从浏览器访问/gitlab子路径时的行为

该 URL 将被重定向/gitlab到/users/sign_in并显示404 Not Found在屏幕上。

这是您正在访问的 URL。

http://{{{AWS CLB DNSName}}}/gitlab

标签： nginxkubernetesgitlabnginx-ingressamazon-eks

解决方案

重定向作为应用程序的默认行为发生，然后您得到 404，因为您没有“/users/sign_in”的条目。因此，也许如果您为“/users/sign_in”添加另一个条目作为路径，它会起作用

作为解决该问题的另一种选择是在路径中使用 / 并使用主机：

spec:
  rules:
    - host: gitlab.example.com
      http:
        paths:
        - path: /
          backend:
            serviceName: gitlab
            servicePort: 12080
