I want to debug the pod in a simple way, therefore I want to start the pod without deployment.

But it will automatically create a deployment

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

So I have to create the nginx.yaml file

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

And create the pod like below, then it creates pod only

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

How can I specify in the command line the kind:Pod to avoid deployment?

// I run under minikue 0.20.0 and kubernetes 1.7.0 under Windows 7
