Deploy the given architecture to vote namespace.
在这里插入图片描述
1、Create a new namespace: name = ‘vote’

kubectl create ns vote

2、

Create new deployment. name: ‘worker’
image: ‘kodekloud/examplevotingapp_worker’
status: ‘Running’

kubectl create deployment worker --image kodekloud/examplevotingapp_worker

3、

Create a new service: name = vote-service
port = ‘5000’
targetPort = ‘80’
nodePort= ‘31000’
service endpoint exposes deployment ‘vote-deployment’

apiVersion: v1
kind: Service
metadata:
  name: vote-service
  namespace: vote
spec:
  type: NodePort
  selector:
    app.kubernetes.io/name: vote-deployment
  ports:
    - protocol: TCP
      port: 5000
      targetPort: 80
      nodePort: 31000

4、

Create a deployment: name = ‘vote-deployment’
image = ‘kodekloud/examplevotingapp_vote:before’
status: ‘Running’

kubectl create deployment vote-deployment --image kodekloud/examplevotingapp_vote:before -n vote

在这里插入图片描述

5、

New Service, name = ‘redis’
port: ‘6379’
targetPort: ‘6379’
type: ‘ClusterIP’
service endpoint exposes deployment ‘redis-deployment’

apiVersion: v1
kind: Service
metadata:
  name: redis-service
  namespace: vote
spec:
  selector:
    app.kubernetes.io/name: redis-deployment
  ports:
