Error 502 Bad Gateway when deploying into ACI

[ChRocheFR]

I followed the tutorial for deploying this app in Azure Container Registry but tried to launch the app with Azure Container Instance (with a Linux machine). The deployment went well but when reaching the site, I got a 502 error.

Do not really know if I made a mistake or if this is due to the code itself.

Try changing the port in docker-compose.yaml from 8080 to 80 and point your browser to: http://127.0.0.1

version: '3'
services:
  azure-vote-back:
    image: redis
    container_name: azure-vote-back
    ports:
        - "6379:6379"

  azure-vote-front:
    build: ./azure-vote
    image: azure-vote-front
    container_name: azure-vote-front
    environment:
      REDIS: azure-vote-back
    ports:
        - "80:80"

Yeah accessing http://127.0.0.1 instead of http://localhost works.
