Hello @segevbor1,
Please follow these full steps to know what you have missed and try again :

Note: We will create deployments again so please before following the steps, Run kubectl delete deployment --all to delete old deployments and avoid any conflicts.

  1. Run git clone https://github.com/mmumshad/example-voting-app-kubernetes-v2.git

  2. Run cd example-voting-app-kubernetes-v2/

  3. Run vim postgres-deployment.yml and modify it’s content as below then save and exit.

Note: It’s a new update from Postgres.

apiVersion: apps/v1
 kind: Deployment
 metadata:
   name: postgres-deployment
   labels:
     app: demo-voting-app
 spec:
   replicas: 1
   selector:
     matchLabels:
       name: postgres-pod
       app: demo-voting-app
   template:
     metadata:
       name: postgres-pod
       labels:
         name: postgres-pod
         app: demo-voting-app
     spec:
       containers:
       - name: postgres
         image: postgres:9.4
         env:
         - name: POSTGRES_USER
           value: postgres
         - name: POSTGRES_PASSWORD
           value: postgres
         - name: POSTGRES_HOST_AUTH_METHOD
           value: trust
         ports:
         - containerPort: 5432

  1. Run kubectl create -f . if you create deployments for the first time, if you created the same deployments before Run kubectl apply -f . .

  2. Run kubectl get service to get the exposed ports.

For example if the output of the command as above you can accces the voting app by hitting One_of_the_worker_nodes_IP:32733 on your browser and the same for the resulting app >> One_of_the_worker_nodes_IP:30013.

Check :

Note: The voting application only accepts one vote per client. It does not register votes if a vote has already been submitted from a client.

Hope this helps!

Thanks,
