Question

我正在尝试使用curl在Kubernetes中创建一个Pod。

这是YAML：

cat > nginx-pod.yaml <<EOF
apiVersion: v1
kind: Pod
metadata:
  name: nginx1
spec:
  containers:
  - name: nginx
    image: nginx:1.7.9
    ports:
    - containerPort: 80
EOF

我具有有权操作的令牌，并且我写了以下curl命令：

curl -k -v -X POST -H "Authorization: Bearer $TOKEN" -H 'Content-Type: application/json;charset=utf-8' https://127.0.0.1:6443/api/v1/namespaces/default/pods --data '{"name":"","namespace":"default","content":"apiVersion: v1\nkind: Pod\nmetadata:\n  name: nginx1\nspec:\n  containers:\n  - name: nginx\n    image: nginx:1.7.9\n    ports:\n    - containerPort: 80\n","validate":true}'

应与nginx-pod.yaml文件等效。
YAML是可以的，因为当我运行kubectl create -f nginx.pod.yaml时，它会创建它。
但是，当我尝试使用curl运行它时，我收到了：

< Content-Length: 617
<
{
  "kind": "Status",
  "apiVersion": "v1",
  "metadata": {

  },
  "status": "Failure",
  "message": "Pod \"\" is invalid: [metadata.name: Required value: name or generateName is required, spec.containers: Required value]",
  "reason": "Invalid",
  "details": {
    "kind": "Pod",
    "causes": [
      {
        "reason": "FieldValueRequired",
        "message": "Required value: name or generateName is required",
        "field": "metadata.name"
      },
      {
        "reason": "FieldValueRequired",
        "message": "Required value",
        "field": "spec.containers"
      }
    ]
  },
  "code": 422
* Connection #0 to host 127.0.0.1 left intact

我尝试将Content-Type更改为Content-type: text/x-yaml，但没有帮助。

任何想法可能是什么原因？

错误之一与“ metadata.name”字段有关。

有效载荷似乎不相等。

这是您要发送的JSON负载：

{
  "name": "",
  "namespace": "default",
  "content": "apiVersion: v1\nkind: Pod\nmetadata:\n  name: nginx1\nspec:\n  containers:\n  - name: nginx\n    image: nginx:1.7.9\n    ports:\n    - containerPort: 80\n",
  "validate": true
}

您的有效载荷应该是这样的。我是用kubectl convert -f <yaml.file> -o=json创建的，这是我相信kubectl在发送有效负载之前所做的。

{
    "kind": "Pod",
    "apiVersion": "v1",
    "metadata": {
        "name": "nginx1",
        "creationTimestamp": null
    },
    "spec": {
        "containers": [
            {
                "name": "nginx",
                "image": "nginx:1.7.9",
                "ports": [
                    {
                        "containerPort": 80,
                        "protocol": "TCP"
                    }
                ],
                "resources": {},
                "terminationMessagePath": "/dev/termination-log",
                "terminationMessagePolicy": "File",
                "imagePullPolicy": "IfNotPresent"
            }
        ],
        "restartPolicy": "Always",
        "terminationGracePeriodSeconds": 30,
        "dnsPolicy": "ClusterFirst",
        "securityContext": {},
        "schedulerName": "default-scheduler"
    },
    "status": {}
}

试过这个，对我来说很好：

curl -k -v -X POST -H "Authorization: Bearer $TOKEN" -H 'Content-Type: application/json;charset=utf-8' https://127.0.0.1:6443/api/v1/namespaces/default/pods -d@payload.json
