Using the :latest tag for container images is not recommended in production environments. It can lead to unpredictable behavior when a new version is pushed to the registry, and it makes it difficult to track which version of the image is running or to roll back to a previous version. It's best practice to pin to a specific, immutable image tag (e.g., a version number or a git SHA).

The TUNNEL_URL is configured to point to http://localhost:8080, but no container is listening on this port. The ingress container, which serves the frontend, is configured to listen on port 3000. The tunnel should forward traffic to the ingress container. Please update the port to 3000 for the tunnel to work correctly.
