Question
Trying to setup an nginx-proxy container for other containers particularly nodejs apps using docker-compose.
I am following the tutorial in this blog. According to the tutorial once the nginx-proxy and let'sencrypt is setup the other apps need the docker-compose.yml file like so to work with the proxy:
version: '3'
services:
example-app:
image: example/example-app
expose:
- 80
environment:
VIRTUAL_HOST: app.example.com
LETSENCRYPT_HOST: app.example.com
LETSENCRYPT_EMAIL: foo@example.com
networks:
default:
external:
name: nginx-proxy
For my nodejs app I’ve setup my docker-compose.yml file as follows:
version: '3'
services:
app:
image: node:carbon
expose:
- 80
volumes:
- .:/home/path/to/code
environment:
VIRTUAL_HOST: app.example.com
LETSENCRYPT_HOST: app.example.com
LETSENCRYPT_EMAIL: foo@example.com
command: npm start
networks:
default:
external:
name: nginx-proxy
I’ve setup simple package.json and index.js files to run a Hello World app. I run docker-compose up -d
, which runs without issues and adds the website. However, when I go to the domain, I get an nginx 503 error. I was wondering if anyone could help point me in the right direction, or maybe even take a different approach to this problem if needed.
