我在尝试应用补丁时遇到以下错误：

答案 0 :(得分：7)
您的yaml配置似乎是从生成的内容中复制粘贴的，因此可能包含诸如creationTimestamp之类的字段，这些字段不属于声明性配置文件。
仔细检查并清理。删除特定于实例的内容。您的最终Yaml应该足够简单，以便您可以轻松理解。

请注意将最后一个resourceVersion放入更新中，您可以使其运行：
kubectl get deployment <DEPLOYMENT-NAME> -o yaml | grep resourceVersion
答案 2 :(得分：3)
您可能已经编辑了相同的导出部署文件。
1-尝试使用以下方法重新导出它：
$pathExists = Invoke-Command -ComputerName <remoteServerName> -Credential $credentials
-ScriptBlock {
Test-Path -Path <AbsolutePath> "UNC path does not work here and you must use Absolute
path. eg. instead of \\Server use D:\Dir1 or D:\Dir1\File1.bat"
}
if (-not ($pathExists))
{
write-host "Directory or File does not exist"
}
else
{
write-host "Directory or File exist"
}
2-在“ deployment-file.yaml”中进行所需的修改
3-应用以下更改：
kubectl get deployment <DEPLOYMENT-NAME> -o yaml > deployment-file.yaml
或：
您可能希望直接编辑部署。.使用：
kubectl apply -f deployment-file.yaml
如果您不熟悉VI编辑器，请更改默认编辑器：kubectl edit deployment <DEPLOYMENT-NAME> -o yaml

从文件中删除这些行：
creationTimestamp:
resourceVersion:
selfLink:
uid:
然后尝试再次申请。
答案 4 :(得分：2)
出现这个错误是因为deployment.yaml 有一个resourceVersion 条目。删除它，因为它不需要，您将能够应用新配置。

我能够在测试环境中重现该问题。重现步骤：
您可以在此处查看YAML文件，这是示例：
---
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，如果要转到 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：

要解决该问题，您需要找到确切的yaml文件，然后根据需要对其进行编辑，然后可以运行$kubectl apply -f nginx-1.yaml
希望此信息对您有帮助。
