Hello,
I am currently having the issue on the voting app… That’s kind of a joke to have such issue(s) while training for CKAD xD
I don’t know if it’s down for today or if I can try again in 10mins…

Hello @yg.herve
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.
Run git clone https://github.com/mmumshad/example-voting-app-kubernetes-v2.git
Run cd example-voting-app-kubernetes-v2/
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:

env:

- name: POSTGRES_PASSWORD

value: trust
ports:
- containerPort: 5432
Run kubectl create -f . if you create deployments for the first time, if you created the same deployments before Run kubectl apply -f . .
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!
