如何在Kubernetes中使用负载均衡器服务公开多个端口 [英] How to expose multiple port using a load balancer services in kubernetes
问题描述
我已经使用Google云平台(容器引擎)创建了一个集群,并使用以下yaml文件部署了一个pod:
I have created a cluster using the google cloud plateform (container engine) and deployed a pod using the following yaml file:
apiVersion: extensions/v1beta1
kind: Deployment
metadata:
name: deployment-name
spec:
replicas: 1
template:
metadata:
name: pod-name
labels:
app: app-label
spec:
containers:
- name: container-name
image: gcr.io/project-id/image-name
resources:
requests:
cpu: 1
ports:
- name: port80
containerPort: 80
- name: port443
containerPort: 443
- name: port6001
containerPort: 6001
然后,我想创建一个服务,以使Pod能够在所有这些端口上进行侦听.我知道他跟随yaml文件可以创建一个在一个端口上侦听的服务:
Then I want to create a service that enables the pod to listen on all these ports. I know that he following yaml file works to create a service that listens on one port:
apiVersion: v1
kind: Service
metadata:
name: service-name
spec:
ports:
- port: 80
targetPort: 80
selector:
app: app-label
type: LoadBalancer
但是,当我希望Pod在这样的多个端口上侦听时,它不起作用:
However when I want the pod to listen on multiple ports like this, it doesn't work:
apiVersion: v1
kind: Service
metadata:
name: service-name
spec:
ports:
- port: 80
targetPort: 80
- port: 443
targetPort: 443
- port: 6001
targetPort: 6001
selector:
app: app-label
type: LoadBalancer
如何使我的Pod监听多个端口?
How can I make my pod listen to multiple ports?
推荐答案
您有两个选择:
- 您可以有多个服务,每个端口一个.正如您所指出的,每个服务将以不同的IP地址结尾
- 您可以使用具有多个端口的一项服务.在这种情况下,必须为所有端口命名.
在您的情况下,该服务将变为:
In your case, the service becomes:
apiVersion: v1
kind: Service
metadata:
name: service-name
spec:
ports:
- name: http
port: 80
targetPort: 80
- name: https
port: 443
targetPort: 443
- name: something
port: 6001
targetPort: 6001
selector:
app: app-label
type: LoadBalancer
这是必要的,以便可以消除端点的歧义.
This is necessary so that endpoints can be disambiguated.
