kubernetes实验挑战三（| Vote App | Redis | Postgresql DB | Deployment | service）
Deploy the given architecture to vote namespace.
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
5、
- New Service, name = ‘redis’
- port: ‘6379’
- targetPort: ‘6379’
- type: ‘ClusterIP’
- service endpoint exposes deployment ‘redis-deployment’
apiVersion: v1
kind: Service

namespace: vote
spec:
selector:
app.kubernetes.io/name: redis-deployment
ports:
- protocol: TCP

6、
Create new deployment, name: ‘redis-deployment’
image: ‘redis:alpine’
Volume Type: ‘EmptyDir’
Volume Name: ‘redis-data’
mountPath: ‘/data’
status: ‘Running’

7、
Create new deployment. name: ‘worker’
image: ‘kodekloud/examplevotingapp_worker’
status: ‘Running’
kubectl create deployment worker --image kodekloud/examplevotingapp_worker -n vote
8、

9、
Create new deployment. name: ‘db-deployment’
image: ‘postgres:9.4’ and add the env: ‘POSTGRES_HOST_AUTH_METHOD=trust’
Volume Type: ‘EmptyDir’
Volume Name: ‘db-data’
mountPath: ‘/var/lib/postgresql/data’
status: ‘Running’
# kubectl create deployment db-deployment --image=postgres:9.4 --dry-run=client -o yaml -n vote > db-deployment.yaml
