docker - (NGINX + Skaffold)-即使编译正确，在本地计算机上运行微服务系统也会始终生成404？

Question

我在本地计算机上运行Multiservices系统，当我在Chrome中键入域时，总是得到:

404 Not Found
nginx/1.19.1

考虑客户:
Dockerfile.dev:

FROM node:13.14.0
WORKDIR /app
COPY package.json .
RUN npm i
COPY . .
CMD ["npm","run","start"]

client-deployment.yaml:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: client-depl
spec:
  replicas: 1
  selector:
    matchLabels:
      app: multi-client
  template:
    metadata:
      labels:
        app: multi-client
    spec:
      containers:
        - name: multi-client
          image: MYDOCKERID/multi-client
                
---
apiVersion: v1
kind: Service
metadata:
  name: client-cluster-ip-service
spec:
  selector:
    app: multi-client
  ports:
    - name: multi-client
      protocol: TCP
      port: 3000
      targetPort: 3000

Skaffold.yaml:

apiVersion: skaffold/v2alpha3
kind: Config
deploy:
  kubectl:
    manifests:
      - ./k8s/*
build:
  local:
    push: false
  artifacts:
    - image: MYDOCKERID/multi-client
      context: client
      docker:
        dockerfile: Dockerfile.dev
      sync:
        manual:
          - src: 'src/**/*.js'
            dest: .


// ... more services , they work OK  

我在主机文件中添加了以下条目:

# Copyright (c) 1993-2009 Microsoft Corp.
#
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
#
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
#
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.
#
# For example:
#
#      102.54.94.97     rhino.acme.com          # source server
#       38.25.63.10     x.acme.com              # x client host
# localhost name resolution is handled within DNS itself.
#   127.0.0.1       localhost
#   ::1             localhost

127.0.0.1 fibonacci.dot

当我在Chrome中输入 fibonacci.dot时，我得到:

这是控制台输出:

我们该如何解决？为什么我会得到404？

根据日志

- ingress.extensions/ingress-fibonacci-service configured

听起来您的应用程序是由入口服务的，因此很可能它所经过的路径不是 /。您可以看到入口中的内容。
您可以检查入口的配置和入口 Controller 的日志(取决于您使用的内容)

$ kubectl get ingress ingress-fibonacci-service -o=yaml
$ kubectl logs <ingress-controller-pod>

如果您使用的是Nginx入口 Controller 。检查配置

$ kubectl exec -t <ingress-pod> cat nginx.conf
