instruction: Create a Dockerfile for workloads
output: ```dockerfile
  from the network.Also, notice that while Kubernetes YAML can appear long and complicated at first, it almost always follows the same pattern:The apiVersion, which indicates the Kubernetes API that parses this objectThe kind indicating what sort of object this isSome metadata applying things like names to your objectsThe spec specifying all the parameters and configurations of your object.Deploy and check your applicationIn a terminal, navigate to where you created bb.yaml and deploy your application to Kubernetes:
  
  $ kubectl apply -f bb.yaml
  You should see output that looks like the following, indicating your Kubernetes objects were created successfully:
  
  deployment.apps/bb-demo created
  service/bb-entrypoint createdMake sure everything worked by listing your deployments:
  
  $ kubectl get deployments
  if all is well, your deployment should be listed as follows:
  
  NAME READY UP-TO-DATE AVAILABLE AGE
  bb-demo 1/1 1 1 40sThis indicates all one of the pods you asked for in your YAML are up and running. Do the same check for your services:
  
  $ kubectl get services
  
  NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
  bb-entrypoint NodePort 10.106.145.116 <none> 3000:30001/TCP 53s
  kubernetes ClusterIP 10.96.0.1 <none> 443/TCP 138d
  In addition to the default kubernetes service, we see our bb-entrypoint service, accepting traffic on port 30001/TCP.Open a browser and visit your Todo app at localhost:30001. You should see your Todo application, the same as when you ran it as a stand-alone container in Part 2 of the tutorial.Once satisfied, tear down your application:
  
  $ kubectl delete -f bb.yaml
  ConclusionAt this point, you have successfully used Docker Desktop to deploy your application to a fully-featured Kubernetes environment on your development machine. You can now add other components to your app and taking advantage of all the features and power of Kubernetes, right on your own machine.In addition to deploying to Kubernetes, you have also described your application as a Kubernetes YAML file. This simple text file contains everything you need to create your application in a running state. You can check it in to version control and share it with your colleagues. This let you distribute your applications to other clusters (like the testing and production clusters that probably come after your development environments).Kubernetes referencesFurther documentation for all new Kubernetes objects used in this article are available here:Kubernetes PodsKubernetes DeploymentsKubernetes Services
