Voting app

The folder k8s-specs contains the yaml specifications of the Voting App's services.

First create the voting-app namespace

$ kubectl create namespace voting-app

Run the following command to create the deployments and services objects:

$ kubectl create -f k8s-specs/ -n voting-app

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.
