Question

我部署了一个舵图（helm install --name=my-release stable/kube-ops-view），该图通过clusterIP创建了一个svc，我试图通过traefik入口创建到它的路由，但是它不起作用

我已经能够使用类似的入口配置路由其他应用程序（nginx）

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: demo-ingress
  namespace: kube-ops-view #svc is created in this namespace
spec:
  rules:
  - host:
    http:
      paths:
      - path: /kube
        backend:
          serviceName: kube-ops-view
          servicePort: 80

入口应该起作用

Answer 1

我能够使其在GKE集群上运行。创建集群后：

1）已安装头盔

2）已安装的NGINX入口控制器]（https://kubernetes.github.io/ingress-nginx/deploy/）

下一步.. 您应该将Rewrite target与nginx.ingress.kubernetes.io/rewrite-target annotation结合使用。

从0.22.0版开始，使用注释进入定义 nginx.ingress.kubernetes.io/rewrite-target不向后与以前的版本兼容。在0.22.0及更高版本中，任何请求URI中需要传递给重新编写的路径必须在捕获组中明确定义。

您的入口应该看起来像

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  annotations:
    kubernetes.io/ingress.class: nginx
    nginx.ingress.kubernetes.io/rewrite-target: /$2
  name: kubeops-kube-ops-view
  namespace: default
spec:
  rules:
  - http:
      paths:
      - backend:
          serviceName: kubeops-kube-ops-view
          servicePort: 80
        path: /kube(/?|$)(.*)

还有另一个选择：您可以在舵图中启用入口，而无需编写入口Yaml。

我的方式：

helm fetch stable/kube-ops-view --untar

编辑values.yaml

ingress:
  enabled: true
  path: /kube(/|$)(.*)
# hostname: kube-ops-view.local
  annotations: {
    kubernetes.io/ingress.class: nginx,
    nginx.ingress.kubernetes.io/rewrite-target: /$2
  }
  tls: []
  ## Secrets must be manually created in the namespace
  #   - secretName: kube-ops-view.local-tls
  #     hosts:
  #       - kube-ops-view.local

编辑模板/ingress.yaml

{{- if .Values.ingress.enabled -}}
apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: {{ template "kube-ops-view.fullname" . }}
  labels:
    app: {{ template "kube-ops-view.fullname" . }}
    chart: "{{ .Chart.Name }}-{{ .Chart.Version }}"
    release: "{{ .Release.Name }}"
    heritage: "{{ .Release.Service }}"
{{- if .Values.ingress.annotations }}
  annotations:
{{ toYaml .Values.ingress.annotations | indent 4 }}
{{- end }}
spec:
  rules:
    - host:
      http:
        paths:
          - path: {{ .Values.ingress.path }}
            backend:
              serviceName: {{ template "kube-ops-view.fullname" . }}
              servicePort: {{ .Values.service.externalPort }}
{{- if .Values.ingress.tls }}
  tls:
{{ toYaml .Values.ingress.tls | indent 4 }}
{{- end -}}
{{- end -}}

验证并安装：掌舵安装--server-dry-run --debug kube-ops-view 头盔安装kube-ops-view --name kubeops

检查结果：

入口路由不适用于使用Helm部署的服务
