Question

我尝试了多种方法来指定docker run命令但最终会出错。

当我运行kubectl get pods时，状态会返回以下错误。

rpc error: code = 2 desc = failed to start container "3329716cb47a0f795b2372dd630ca1017b0bad8bf4ab0e05490d1ac5eb28ca1b": Error response from daemon: {"message":"container 3329716cb47a0f795b2372dd630ca1017b0bad8bf4ab0e05490d1ac5eb28ca1b encountered an error during CreateProcess: failure in a Windows system call: The system cannot find the file specified.

我用于kubectl apply命令创建pod的Json文件是：

{
 "apiVersion": "v1",
 "kind": "Pod",
 "metadata": {
   "name": "buildagent",
   "labels": {
     "name": "buildagent"
   }
 },
 "spec": {
   "containers": [
     {
       "name": "buildagent",
       "image": "raychen320/buildagent:1.0",
       "command": [
                    "powershell.exe -command",
                    "docker run -e VSTS_ACCOUNT=apitest -e VSTS_TOKEN=tgctxxx -e VSTS_POOL=testpool --name myagent raychen320/buildagent:1.0"
            ],
       "ports": [
         {
         "containerPort": 80
         }
       ]
     }
   ],
   "nodeSelector": {
    "beta.kubernetes.io/os": "windows"
    }
  }
}

我应该在命令中设置什么？

Answer 1

您正在尝试启动一个名为powershell.exe -command的可执行文件，该文件显然不存在。你应该尝试推出的更像是：

command: "powershell.exe"
args:
- "-command"
- "docker run..."

Answer 2

Docker在您的系统路径中找不到powershell.exe。也许你应该在“命令”

中使用powershell.exe的完整路径

无法在json中使用指定命令启动容器
