Question

我有一个正在运行的詹金斯（Jenkins）吊舱，我正在尝试执行以下命令：

sudo kubectl --kubeconfig /opt/jenkins_home/admin.conf apply -f /opt/jenkins_home/ab-kubernetes/ab-back.yml

出现以下错误：

服务器错误（未找到）：服务器找不到请求的资源

这里有什么问题？

ab-back.yml文件

更新：

kubectl version如下：

Client Version: version.Info{Major:"1", Minor:"11", GitVersion:"v1.11.0", GitCommit:"91e7b4fd31fcd3d5f436da26c980becec37ceefe", GitTreeState:"clean", BuildDate:"2018-06-27T20:17:28Z", GoVersion:"go1.10.2", Compiler:"gc", Platform:"linux/amd64"}
Server Version: version.Info{Major:"1", Minor:"6", GitVersion:"v1.6.0", GitCommit:"fff5156092b56e6bd60fff75aad4dc9de6b6ef37", GitTreeState:"clean", BuildDate:"2017-03-28T16:24:30Z", GoVersion:"go1.7.5", Compiler:"gc", Platform:"linux/amd64"}

在以--v=4的形式应用日志时，kubectl apply可以正常工作并提供日志，如下所示：

I0702 11:40:17.721604    1601 merged_client_builder.go:159] Using in-cluster namespace
I0702 11:40:17.734648    1601 decoder.go:224] decoding stream as YAML
service/dg-back-svc created
deployment.extensions/dg-core-backend-d created

但是kubectl create给出的错误是：

I0702 11:41:12.265490    1631 helpers.go:201] server response object: [{
  "metadata": {},
  "status": "Failure",
  "message": "the server could not find the requested resource",
  "reason": "NotFound",
  "details": {

        "reason": "UnexpectedServerResponse",
        "message": "unknown"
      }
    ]
  },
  "code": 404
}]

此外，在执行kubectl get pods --v=10时，它还会将日志记录为：

  "metadata": {},
  "status": "Failure",
  "message": "only the following media types are accepted: application/json, application/yaml, application/vnd.kubernetes.protobuf",
  "reason": "NotAcceptable",

}

Answer 1

问题出在版本中，请尝试使用客户端的旧版本或升级服务器。 kubectl支持一种版本的向前和向后倾斜：

来自documentation

客户端的偏斜版本不得超过大师，但最多可以领导一个次要版本。对于例如，v1.3主节点应与v1.1，v1.2和v1.3节点一起使用，并应与v1.2，v1.3和v1.4客户端一起使用。

Answer 2

Kubernetes服务器没有extensions/v1beta1此资源。这就是为什么您无法创建dg-core-backend-d的原因您可以通过输入kubectl api-versions

进行检查

从内部Pod中创建kubectl
