instruction: Create a Dockerfile for Alpine Linux with production best practices
output: ```dockerfile
  From the Docker Dashboard, navigate to Settings, and select the Kubernetes tab.Select the checkbox labeled Enable Kubernetes, and select Apply. Docker Desktop automatically sets up Kubernetes for you. You'll know that Kubernetes has been successfully enabled when you see a green light beside 'Kubernetes running' in the Settings menu.To confirm that Kubernetes is up and running, create a text file called pod.yaml with the following content:
  
  apiVersion: v1
  kind: Pod
  metadata:
   name: demo
  spec:
   containers:
   - name: testpod
   image: alpine:latest
   command: ["ping", "8.8.8.8"]This describes a pod with a single container, isolating a simple ping to 8.8.8.8.In PowerShell, navigate to where you created pod.yaml and create your pod:
  
  $ kubectl apply -f pod.yaml
  Check that your pod is up and running:
  
  $ kubectl get pods
  You should see something like:
  
  NAME READY STATUS RESTARTS AGE
  demo 1/1 Running 0 4sCheck that you get the logs you'd expect for a ping process:
  
  $ kubectl logs demo
  You should see the output of a healthy ping process:
  
  PING 8.8.8.8 (8.8.8.8): 56 data bytes
  64 bytes
