• # 查看service 詳細信息
• kubectl describe service 資源名

# 服務名稱
Name:              nginx
# 命名空間
Namespace:         default
# 標籤
Labels:            run=nginx
Annotations:       <none>
# 標籤
Selector:          run=nginx
# 網絡代理類型
Type:              ClusterIP
# 集羣惟一IP
IP:                10.10.10.17
# Service端口
Port:              <unset>  88/TCP
# 容器端口
TargetPort:        80/TCP
# 代理容器IP
Endpoints:         172.17.1.2:80,172.17.2.2:80,172.17.2.3:80

注：kubernetes默認負載均衡模式爲ClusterIP。

注：標籤主要是識別資源的描述符號。

注：顯示集羣信息 kubectl cluster-info 顯示運行API狀況。
