[FIXED] How to set reverse proxy using jwilder/nginx-proxy?

Issue

I'm trying to set a reverse proxy using jwilder/nginx-proxy container.

I have a small Express app:

var express = require("express");
var app = express();

app.get("/api", (req, res, next) => {
  res.json({ hello: "world" });
});

app.listen(3000, () => {
  console.log("Server running on port 3000");
});

and a docker-compose.yml:

version: "3.4"
services:
  reverse-proxy:
    image: jwilder/nginx-proxy
    ports:
      - 80:80
    volumes:
      - /var/run/docker.sock:/tmp/docker.sock:ro
    networks:
      - testt

  testt:
    container_name: testt
    image: node:lts
    working_dir: /var/www/html/app/
    entrypoint: /bin/bash
    environment:
      - HOST=0.0.0.0
      - VIRTUAL_HOST=testt.dev # for reverse proxy
      - VIRTUAL_PORT=3000 # for reverse proxy
    ports:
      - 3000:3000
    volumes:
      - ./testt/:/var/www/html/app
    tty: true
    networks:
      - testt

networks:
  testt:
    external: true

That is all I have set. Nothing else.

When I run localhost:3000/api I get the expected result {"hello":"world"}. The same I'd expect to get when I run http://testt.dev/api in the browser, but it is not working (DNS_PROBE_FINISHED_NXDOMAIN).

What else do I have to set and where? Do I have to set something to HOSTS file?

Thank you

Solution

I think you need url and then letesencrypt_host and letsencrypt_email if you wants certs. Try:

version: '3.7'
services:

    ghost01:
        image: "ghost"
        user: "1000"
        environment:
            - url=https://test01.zathras.io
            - VIRTUAL_HOST=test01.zathras.io
            - VIRTUAL_HOST_ALIAS=test01.zathras.io
            - LETSENCRYPT_HOST=test01.zathras.io
            - LETSENCRYPT_EMAIL=qdzlug@gmail.com
        networks:
            - webproxy
networks:
    webproxy:
        external: true
