kubernetes - 如何在命令行中启动 pod，而不在 kubernetes 中部署？

Question

我想以简单的方式调试 pod，因此我想在不部署的情况下启动 pod。

但它会自动创建部署

$ kubectl run nginx --image=nginx --port=80
deployment "nginx" created

所以我必须创建 nginx.yaml 文件

---
apiVersion: v1
kind: Pod
metadata:
  name: nginx
spec:
  containers:
    - name: nginx
      image: nginx
      ports:
        - containerPort: 80

并像下面一样创建 pod，然后它只创建 pod

kubectl create -f nginx.yaml
pod "nginx" created

如何在命令行中指定 kind:Pod 以避免部署？
