使用入口在远程Kubernetes集群中的访问服务

Question

我正在尝试访问部署在远程机器上的现有kubernetes集群中的服务。我已经将群集配置为可以从本地Mac通过kubectl访问。

$ kubectl cluster-info
Kubernetes master is running at https://192.168.58.114:6443
KubeDNS is running at https://192.168.58.114:6443/api/v1/namespaces/kube-system/services/kube-dns:dns/proxy

我要连接的服务的入口配置为：

kind: Ingress
apiVersion: extensions/v1beta1
metadata:
  name: gw-ingress
  namespace: vick-system
  selfLink: /apis/extensions/v1beta1/namespaces/vick-system/ingresses/gw-ingress
  uid: 52b62da6-01c1-11e9-9f59-fa163eb296d8
  resourceVersion: '2695'
  generation: 1
  creationTimestamp: '2018-12-17T06:02:23Z'
  annotations:
    kubectl.kubernetes.io/last-applied-configuration: >
      {"apiVersion":"extensions/v1beta1","kind":"Ingress","metadata":{"annotations":{"kubernetes.io/ingress.class":"nginx","nginx.ingress.kubernetes.io/affinity":"cookie","nginx.ingress.kubernetes.io/session-cookie-hash":"sha1","nginx.ingress.kubernetes.io/session-cookie-name":"route"},"name":"gw-ingress","namespace":"vick-system"},"spec":{"rules":[{"host":"wso2-apim-gateway","http":{"paths":[{"backend":{"serviceName":"gateway","servicePort":8280},"path":"/"}]}}],"tls":[{"hosts":["wso2-apim-gateway"]}]}}
    kubernetes.io/ingress.class: nginx
    nginx.ingress.kubernetes.io/affinity: cookie
    nginx.ingress.kubernetes.io/session-cookie-hash: sha1
    nginx.ingress.kubernetes.io/session-cookie-name: route
spec:
  tls:
    - hosts:
        - wso2-apim-gateway
  rules:
    - host: wso2-apim-gateway
      http:
        paths:
          - path: /
            backend:
              serviceName: gateway
              servicePort: 8280
status:
  loadBalancer:
    ingress:
      - ip: 172.17.17.100

我的服务清单是：

我的/ etc / hosts文件如下所示：

##
# Host Database
#
# localhost is used to configure the loopback interface
# when the system is booting.  Do not change this entry.
##
127.0.0.1   localhost
255.255.255.255 broadcasthost
::1             localhost

172.17.17.100 wso2-apim-gateway wso2-apim wso2sp-dashboard

从本地浏览器访问此服务应使用的URL是什么？我应该再进行其他配置吗？

Answer 1

访问此端口最简单的方法是端口转发，无需修改主机文件。

kubectl -n vick-system port-forward svc/wso2sp-dashboard 9643

这将允许您浏览到http://localhost:9643并访问该服务。

请注意，svc/name仅支持kubectl >= 1.10
