【CKA模拟题】如何发布一个SVC资源

题干

For this question, please set this context (In exam, diff cluster name)

kubectl config use-context kubernetes-admin@kubernetes

You have an existing Nginx pod named nginx-pod . Perform the following steps:

• Expose the nginx-pod internally within the cluster using a Service named nginx-service .
• Use port forwarding to service to access the Welcome content of nginx-pod using the curl command.

你有一个名为Nginx -pod的现有Nginx pod。请执行以下步骤:

• 使用一个名为nginx-service的服务在集群内部公开nginx-pod。
• 使用端口转发服务，使用curl命令访问nginx-pod的欢迎内容。

解题思路

1. 切换K8S集群环境

kubectl config use-context kubernetes-admin@kubernetes

2. 通过kubectl export命令发布SVC

controlplane $ kubectl expose pod nginx-pod  --name nginx-service                          
service/nginx-service exposed

3. 验证结果

controlplane $ k get svc nginx-service 
NAME            TYPE        CLUSTER-IP      EXTERNAL-IP   PORT(S)   AGE
nginx-service   ClusterIP   10.103.170.66   <none>        80/TCP    2m23s
