docker stack deploy --compose-file docker-stack.yml vote
```
Run the app in Kubernetes
-------------------------
The folder k8s-specifications contains the yaml specifications of the Voting App's services.
Run the following command to create the deployments and services objects:
```
$ kubectl create -f k8s-specifications/
deployment "db" created
service "db" created
deployment "redis" created
service "redis" created
deployment "result" created
service "result" created
deployment "vote" created
service "vote" created
deployment "worker" created
```
The vote interface is then available on port 31000 on each host of the cluster, the result one is available on port 31001.
