I have two apps (app1 and app2) and I would like to run them on my domains (domain1 and domain2). I use docker containers to do this and a docker reverse proxy. If I run each docker app independently, they work well. When I execute docker-compose up -d and I visit my domains, I can see the following message: Welcome to nginx!. I can't see my apps running.

My docker-compose.yml is the following:

version: "3.7"

services:
 proxy:
  image: jwilder/nginx-proxy
  container_name: proxy
  labels:
   com.github.jrcs.letsencrypt_nginx_proxy_companion.nginx_proxy: "true"
  ports:
   - "80:80"
   - "443:443"
  volumes:
   - certs:/etc/nginx/certs
   - vhostd:/etc/nginx/vhost.d
   - html:/usr/share/nginx/html
   - /var/run/docker.sock:/tmp/docker.sock

 letsencrypt:
  image: jrcs/letsencrypt-nginx-proxy-companion
  container_name: letsencrypt
  environment:
   - NGINX_PROXY_CONTAINER=proxy
  volumes:
   - certs:/etc/nginx/certs
   - vhostd:/etc/nginx/vhost.d
   - html:/usr/share/nginx/html
   - /var/run/docker.sock:/var/run/docker.sock

 app1:
  image: app1_image
  container_name: myapp1
  expose:
   - "9090"
  environment:
   - VIRTUAL_PORT=9090
   - VIRTUAL_HOST=domain1.com www.domain1.com
   - LETSENCRYPT_HOST=domain1.com www.domain1.com
   - [email protected]
  volumes:
   - /srv/shiny-server/app1/app/data:/srv/shiny-server/app1/app/data

 app2:
  image: app2_image
  container_name: myapp2
  expose:
   - "8080"
  environment:
   - VIRTUAL_PORT=8080
   - VIRTUAL_HOST=domain2.com www.domain2.com
   - LETSENCRYPT_HOST=domain2.com www.domain2.com
   - [email protected]
  volumes:
   - /srv/shiny-server/app2/app/data:/srv/shiny-server/app2/app/data

volumes:
 certs:
 html:
 vhostd:

If I don't use the detach mode and I execute the docker containers, I get the following error:

$ docker-compose up

I don't know if this error is causing the problem, buy I just see on my domains: Welcome to nginx! I can't see my apps running.

CodePudding user response：

I can't see your problem, but I can give some advices.

1. Mount of vhostd
   You have a mount vhostd:/etc/nginx/vhost.d. If you have settings in there, then you should share them with us.
   If not, then just remove the mount.

2. Multidomain pattern
   You specified multiple domains in a different pattern as jwilder/nginx-proxy.
   Instead of VIRTUAL_HOST=domain1.com www.domain1.com you should write VIRTUAL_HOST=domain1.com,www.domain1.com.
   See jwilder/nginx-proxy, chapter "Multiple Hosts"
