Question

我是Kubernetes平台的新手，试图启用HTTPS安全连接到Kubernetes平台中部署的tomcat Web应用程序。我对manifest.yml与部署，服务和入口控制器有关感到困惑。

apiVersion: v1

  labels:
    app: tomcat-webapp
spec:
  ports:
    - port: 80
      targetPort: 8080
      #nodePort: 30010
      protocol: TCP
      name: http

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: tomcat-webapp
spec:
  rules:
    - host: "tomcat-webapp.apps.net"
      http:
        paths:
          - path: /
            backend:
              serviceName: tomcat-webapp
              servicePort: 80
  tls:
    - hosts:
        # dont forget to update this url too
        - "tomcat-webapp.apps.net"

所以我还必须在部署（在端口：-containerPort：8080下）服务中指定端口8443（Https端口）（例如端口：-端口：80 targetPort：8080协议：TCP名称：http）和入口（在下面） backend：serviceName：tomcat-webapp servicePort：80）吗？

保持简单：

apiVersion: v1
kind: Service
metadata:
  name: tomcat-webapp
  labels:
    app: tomcat-webapp
spec:
  ports:
    - port: 8080
  selector:
    app: tomcat-webapp

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: tomcat-webapp
spec:
  rules:
    - host: "tomcat-webapp.apps.net"
      http:
        paths:
          - path: /
            backend:
              serviceName: tomcat-webapp
              servicePort: 8080
  tls:
    - hosts:
        - "tomcat-webapp.apps.net"`

据我从您的Deployment配置了解，您的Java应用程序在端口8080上运行，并期望https流量。这不适用于上述Ingress配置-您的Java应用程序应在端口8080上侦听并期望http流量。

如果您确实希望Java应用程序侦听HTTPS，则可以通过以下方式配置Ingress：

apiVersion: extensions/v1beta1
kind: Ingress
metadata:
  name: tomcat-webapp
  annotations:
    kubernetes.io/ingress.class: "nginx"
    nginx.ingress.kubernetes.io/backend-protocol: "HTTPS"
... # the rest is the same
