找不到Kubernetes Ingress Nginx控制器

Question

Ingress Nginx控制器正在为React应用程序返回404 Not Found。我将其缩小到React应用程序，因为如果我尝试访问posts.com/posts，它实际上会返回现有帖子的JSON列表，但对于前端应用程序，它会不断显示得到http://posts.com/404(未找到(

我看了看其他一些堆叠式的问题，但遗憾的是没有用。

入口srv.yaml

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
name: ingress-srv
annotations:
kubernetes.io/ingress.class: nginx
nginx.ingress.kubernetes.io/use-regex: "use"

port:

- path: /?(.*)
pathType: Prefix
backend:
service:

客户端depl.yaml

spec:
selector: 
app: client
ports: 
- name: client

port: 3000
targetPort: 3000

前端Dockerfile

FROM node:alpine
ENV CI=true
WORKDIR /app
COPY package.json ./
RUN npm install
COPY ./ ./ 
CMD ["npm", "start"]

记录吊舱：

如果您需要任何其他日志，我很乐意提供。谢谢

在您的yamls中，有一个路径"/"用于处理查询参数，但该路径将不接收来自"查询"的业务/"路径，因为没有匹配的前缀。所以你必须创建一条路径"/"使用类型前缀来解决问题。然后您可以忽略当前的"/"路径，因为它将匹配前缀为"0"/"路径

请尝试这个：

ingress-srv.yaml

Answer 2

所以这个问题真的很愚蠢-我实际上设置了nginx.ingress.kubernetes.io/use-regex:"使用"；代替nginx.ingress.kubernetes.io/use-regex:"；真的"；。。。经过三天的文档检查，我终于找到了它。如果有人遇到类似的问题，你就知道了。

您必须在规范中添加以下规则

- path: /
pathType: Prefix
backend:
service:
name: client-srv
port:
number: 3000

这匹配所有路径。
