我能在我的测试环境中重现这个问题。重现步骤如下：
- 从 Kubernetes Engine > 工作负载 > 部署 创建一个部署。
- 输入您的应用程序名称、命名空间和标签。
- 选择集群或创建新的集群。
您可以在这里查看 YAML 文件，这里是示例：
---
apiVersion: "apps/v1"
kind: "Deployment"
metadata:
name: "nginx-1"
namespace: "default"
labels:
app: "nginx-1"
spec:
replicas: 3
selector:
matchLabels:
app: "nginx-1"
template:
metadata:
labels:
app: "nginx-1"
spec:
containers:
- name: "nginx"
image: "nginx:latest"
---
apiVersion: "autoscaling/v2beta1"
kind: "HorizontalPodAutoscaler"
metadata:
name: "nginx-1-hpa"
namespace: "default"
labels:
app: "nginx-1"
spec:
scaleTargetRef:
kind: "Deployment"
name: "nginx-1"
apiVersion: "apps/v1"
minReplicas: 1
maxReplicas: 5
metrics:
- type: "Resource"
resource:
name: "cpu"
targetAverageUtilization: 80
部署后，如果您进入 Kubernetes Engine > 工作负载 > nginx-1（单击它）
a.) 您将获得部署详细信息（概述、详细信息、修订历史记录、事件、YAML）
b.) 单击 YAML 并从 YAML 选项卡中复制内容
c.) 创建新的 YAML 文件并粘贴内容并保存文件
d.) 现在，如果您运行命令 $kubectl apply -f newyamlfile.yaml，它将显示以下错误：
Warning: kubectl apply should be used on resource created by either kubectl create --save-config or kubectl apply

为了解决这个问题，你需要找到准确的yaml文件，然后按照你的要求进行编辑，之后你可以运行
$kubectl apply -f nginx-1.yaml。
希望这些信息对你有所帮助。
