Kubernetes nginx入口多路径

Question

我有点麻烦，我想创建具有多条路径的入口

下面是我的/template/ingress.yaml

{{- if .Values.ingress.enabled -}}
{{- $ingressPath := .Values.ingress.path -}}
{{- $appName := .Values.appName -}}
apiVersion: extensions/v1beta1
kind: Ingress
metadata: 
  name: {{ .Values.appName }}-ingress
  labels:
    app: {{ .Values.appName }}
    chart: {{ template "chart.chart" . }}
    release: {{ .Release.Name }}
    heritage: {{ .Release.Service }}
{{- with .Values.ingress.annotations }}
  annotations:
{{ toYaml . | indent 4 }}
{{- end }}
spec:
{{- if .Values.ingress.tls }}
  tls:
  {{- range .Values.ingress.tls }}
    - hosts:
      {{- range .hosts }}
        - {{ . }}
      {{- end }}
      secretName: {{ .secretName }}
  {{- end }}
{{- end }}
  rules:
  {{- range .Values.ingress.hosts }}
    - host: {{ . }}
      http:
        paths:
          - path: {{ $ingressPath }}
            backend:
              serviceName: {{ $appName }}-service
              servicePort: 80
  {{- end }}
{{- end }}

这是我的values.yaml文件

appName: vsemPrivet
replicaCount: 1
image:
  repository: kakoito.domen.kg
  tag: dev-56739-272faaf
  pullPolicy: Always
imagePullSecretName: regcred
nodeSelector:
  project: vazhni-project
service: vsem-privet
  name: 
  type: ClusterIP
  protocol: TCP
  targetPort: 8080

## Configure ingress resourse
## ref: https://kubernetes.io/docs/concepts/services-networking/ingress/
ingress:
  enabled: true
  annotations:
    kubernetes.io/ingress.class: "nginx-prod-01"
    nginx.ingress.kubernetes.io/rewrite-target: "/"
    nginx.ingress.kubernetes.io/enable-cors: "true"
    nginx.ingress.kubernetes.io/cors-allow-methods: "GET, POST, PUT, DELETE, OPTIONS, HEAD"
    nginx.ingress.kubernetes.io/cors-allow-origin: "*"
    nginx.ingress.kubernetes.io/cors-allow-credentials: "true"
    nginx.ingress.kubernetes.io/cors-allow-headers: "*"
    nginx.ingress.kubernetes.io/cors-max-age: "3600"
    nginx.ingress.kubernetes.io/from-to-www-redirect: "true"
  hosts:
    - mirtebe4elovek.com
  path: /letter
  hosts:
    - mirtebe4elovek.com
  path: /swagger-ui
  hosts:
    - mirtebe4elovek.com
  path: /webjars

  tls:
    - secretName: ssl-secret
      hosts:
        - qa-ibank.anthill.fortebank.com

因此，在我的场景中，我想创建3个不同的路径，但是当我执行helm install，然后kubectl描述我的操作时，我得到了以下结果

Name:             service-core-ingress
Namespace:        default
Address:          
Default backend:  default-http-backend:80 (<none>)
TLS:
  ssl-secret terminates mirtebe4elovek.com
Rules:
  Host                            Path  Backends
  ----                            ----  --------
  mirtebe4elovek.com  
                                  /webjars   my-service:80 (<none>)
Annotations:
  kubernetes.io/ingress.class:                         nginxnginx
  nginx.ingress.kubernetes.io/cors-allow-methods:      GET, POST, PUT, DELETE, OPTIONS, HEAD
  nginx.ingress.kubernetes.io/cors-max-age:            3600
  nginx.ingress.kubernetes.io/rewrite-target:          /
  nginx.ingress.kubernetes.io/cors-allow-credentials:  true
  nginx.ingress.kubernetes.io/cors-allow-headers:      *
  nginx.ingress.kubernetes.io/cors-allow-origin:       *
  nginx.ingress.kubernetes.io/enable-cors:             true
  nginx.ingress.kubernetes.io/from-to-www-redirect:    true
Events:                                                <none>

如你所见，我只有一个路径/webjars，但是另外两个在哪里? /letters和/swagger-ui，我已经在我的values.yaml文件中描述过了，我该如何解决这个问题呢？

在Helm中，range运算符用于遍历集合。看起来这里需要在单个主机mirtebe4elovek.com上有多条路径

您可以按如下方式修改ingress.yaml。

rules:

    - host: {{ .Values.ingress.host }}
      http:
        paths:
        {{- range .Values.ingress.paths }}
          - path: {{ . }}
            backend:
              serviceName: {{ $appName }}-service
              servicePort: 80
        {{- end }}

value.yaml文件如下所示：

ingress:
  enabled: true
  annotations:
    kubernetes.io/ingress.class: "nginx-prod-01"
    nginx.ingress.kubernetes.io/rewrite-target: "/"
    nginx.ingress.kubernetes.io/enable-cors: "true"
    nginx.ingress.kubernetes.io/cors-allow-methods: "GET, POST, PUT, DELETE, OPTIONS, HEAD"
    nginx.ingress.kubernetes.io/cors-allow-origin: "*"
    nginx.ingress.kubernetes.io/cors-allow-credentials: "true"
    nginx.ingress.kubernetes.io/cors-allow-headers: "*"
    nginx.ingress.kubernetes.io/cors-max-age: "3600"
    nginx.ingress.kubernetes.io/from-to-www-redirect: "true"
  host: "mirtebe4elovek.com"
  paths:
    - "/letter"
    - "/swagger-ui"
    - "/webjars"
