Deployment和Service删除

🗑️ 完整删除步骤

1. 删除 Deployment（会同时删除 Pod）

kubectl delete deployment nginx -n default

这会删除名为 nginx 的 Deployment
Deployment 管理的所有 Pod 也会被自动删除

2. 删除 Service

kubectl delete service nginx-svc-nodeport -n default

这会删除 NodePort 类型的 Service

3. 验证删除结果

# 检查 Deployment
kubectl get deployments -n default

# 检查 Pod
kubectl get pods -n default

# 检查 Service
kubectl get services -n default

所有相关资源应显示 "No resources found"

#默认命名空间是 default
#查看deployment
[root@k8s-master ~]# kubectl get deployments.apps 
NAME    READY   UP-TO-DATE   AVAILABLE   AGE
nginx   2/2     2            2           116s
#删除名为nginx的deployment（会同时删除 Pod）（因为是在default空间里，所以-n指向default命名空间删除名为nginx的deployment）
[root@k8s-master ~]# kubectl delete deployment nginx -n default
deployment.apps "nginx" deleted
#删除 Service
#这会删除 NodePort 类型的 Service
[root@k8s-master ~]# kubectl delete service nginx-svc-nodeport -n default
