Nginx-ingress设置注释与Kubernetes Helm一起使用安装values.yaml-Java 学习之路

在Google Cloud 平台/容器引擎上运行 - 如何将其设置为指向此Ingress，如下所示？

我已经使用Helm在Kubernetes上安装了Nginx-ingress，它适用于 default backend - 404 .

我希望能够使用不同的http uri路径，如 <domain.com>/v1 ， <domain.com>/v2 等 .

对于我想要使用Ingress的图表，我在 values.yaml 中有以下内容：

# Default values for app-go.
# This is a YAML-formatted file.
# Declare variables to be passed into your templates.

replicaCount: 1

image:
  repository: gcr.io/<project name>/app-go
  tag: latest
  pullPolicy: IfNotPresent

service:
  type: ClusterIP
  port:

# kubernetes.io/tls-acme: "true",

ingress:
  enabled: true
  annotations: {
    kubernetes.io/ingress.class: "nginx",
    kubernetes.io/ingress.global-static-ip-name: "kube-ingress"
  }

    # kubernetes.io/ingress.class: nginx
    # kubernetes.io/tls-acme: "true"
  path: /
  hosts:
    - <domain.com>
  tls: []
  #  - secretName: chart-example-tls
  #    hosts:
  #      - chart-example.local

resources: {}
  # We usually recommend not to specify default resources and to leave this as a conscious
  # choice for the user. This also increases chances charts run on environments with little
  # resources, such as Minikube. If you do want to specify resources, uncomment the following
  # lines, adjust them as necessary, and remove the curly braces after 'resources:'.
  # limits:
  #  cpu: 100m
  #  memory: 128Mi
  # requests:
  #  cpu: 100m
  #  memory: 128Mi

nodeSelector: {}

tolerations: []

affinity: {}

如何为不同路径指定Nginx-ingress的注释 .

helm version      
Client: &version.Version{SemVer:"v2.8.1", GitCommit:"6af75a8fd72e2aa18a2b278cfe5c7a1c5feca7f2", GitTreeState:"clean"}
Server: &version.Version{SemVer:"v2.8.0", GitCommit:"14af25f1de6832228539259b821949d20069a222", GitTreeState:"clean"}

如何为不同路径指定Nginx-ingress的注释 .

如果您的意思是在同一域名中使用基于URI的不同入口注释（可用于指向不同服务的不同路径），那么简单的答案是：您不能 .

注释是kubernetes API对象上元数据的一部分，您的整个Ingress就是这样一个对象，因此您无法根据http uri路径对它进行区分 .

我继续并转载你的用例 .
假设通过helm安装nginx入口控制器顺利进行，当列出资源时，一切似乎都很好，你需要在入口yaml文件中指定路径，如下所示：

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: ingress-resource
  annotations:
    kubernetes.io/ingress.class: nginx
    nginx.ingress.kubernetes.io/ssl-redirect: "false"
spec:
  rules:
  - host: test.demo.com
    http:
      paths:
      - path: /path1
        backend:
          serviceName: s1
          servicePort: 8080
      - path: /path2
        backend:
          serviceName: s1
          servicePort: 8080
      - path: /path3
        backend:
          serviceName: s2
          servicePort: 80
  - host: demo.test.com
    http:
      paths:
      - backend:
          serviceName: s2
          servicePort: 80

然后，卷曲-H -I 'Host: test.demo.com' http://external-lb-ip/path1，例如，应该返回200 .
