Path 如何修复ingress 404默认后端

几个月前我开始使用Kubernetes，实际上我将我的微服务迁移到我的rancher集群（RKE）。一切都很好，我的部署很好，服务也很好。我想使用入口

一切看起来都很好，服务由入口找到，播客由服务找到。然而，当我尝试去该网站时，我有一个来自入口控制器的404错误页面

您可以看到我对两条路径的配置：一条是nginx，另一条是grafana。 有人知道如何修复它并使用入口来执行反向代理

非常感谢你的帮助

我尝试在没有结果的情况下使用“重写目标”，不推荐使用“添加基本url”

实际上，Nginx入口控制器处理所有无法到达目标位置的请求，并将它们发送到默认位置，从而在

default backend-404

页面中生成每个请求

既然您已经决定实现基于路径的路由方案，重写规则可以通过

nginx.ingres.kubernetes.io/rewrite target

：

应用上述

入口

清单后，可以在以下重写示例中提供基于路径的路由：

www.scol-ea.ovh/nginx->www.scol-ea.ovh/

www.scol-ea.ovh/grafana->www.scol-ea.ovh/

---

我不建议跨已发布的清单或任何其他数据对象共享任何用户敏感数据，类似于您的公共端点。

我认为您应该在yaml中使用

nginx.ingres.kubernetes.io/backend-protocol:HTTPS

注释如果您在kubernetes中使用nginx作为部署代理，并且面临此问题，那么下面的配置可以解决重定向问题

您可以在grafan.ini文件中包含以下变量，也可以作为env变量公开，如下所示

GF_SERVER_DOMAIN=abc.google.com
GF_SERVER_ROOT_URL=%(protocol)s://%(domain)s:/grafana

因此，Grafana部署将如下图所示

        apiVersion: apps/v1
        kind: Deployment
        metadata:
          name: grafana
          namespace: monitoring
        spec:
          replicas: 1
          selector:
            matchLabels:
              app: grafana
            spec:
              containers:
              - name: grafana
                image: grafana/grafana:latest
                env:
                - name: GF_SERVER_DOMAIN
                  value: "abc.google.com"
                - name: GF_SERVER_ROOT_URL
                  value: "%(protocol)s://%(domain)s:/grafana"

                ports:
                - name: grafana
                  containerPort: 3000
                resources:
                  limits:
                    memory: "2Gi"
                    cpu: "1000m"
                  requests: 
                    memory: "1Gi"
                    cpu: "500m"
                volumeMounts:
                  - mountPath: /var/lib/grafana
                    name: grafana-storage-volume
                  - mountPath: /etc/grafana/provisioning/datasources
                    name: grafana-datasources
                    readOnly: false

您必须更新nginx服务器位置块，如下所示

       location /grafana {
           proxy_pass http://grafana.monitoring.svc.cluster.local:3000;
           rewrite ^/grafana/(.*) /$1 break;
           proxy_set_header Host $host;
        }

       location /grafana {
           proxy_pass http://grafana.monitoring.svc.cluster.local:3000;
           rewrite ^/grafana/(.*) /$1 break;
           proxy_set_header Host $host;
        }
