Cluster information:
Kubernetes version: 1.24.1
Cloud being used: Azure
Installation method: Helm Chart
Explanation
I am very new to Kubernetes and decided to migrate one little side-project I have hosted here: GitHub - MrDesjardins/realtimepixel
I am trying to expose a frontend service that connects to a backend service that connects to a Redis service. Locally, I have a docker-compose, and it works. Now, moving to Kubernetes, I have some success (everything is green under Azure, but the exposed IP does not return anything. I added an ingress but haven’t seen a difference from only using the frontend service being a LoadBalancer.
Debug yaml output
The Helm Chart is producing the following output. I do not use that output, I use az login and Helm to install everything on Azure (see the action if relevant here realtimepixel/k8sdeploy.yml at master · MrDesjardins/realtimepixel · GitHub)

Can someone guide me on what is my mistake?
