Error running notify command: nginx -s reload, exit status 1

[Harper04]

Hi,

i have a problem and no idea where to start debugging/i'm doing wrong.
I get the following log:

root@root:~# docker run -p 80:80 -v /var/run/docker.sock:/tmp/docker.sock:ro jwilder/nginx-proxy
forego     | starting nginx.1 on port 5000
forego     | starting dockergen.1 on port 5100

dockergen.1 | 2016/08/15 13:08:13 Contents of /etc/nginx/conf.d/default.conf did not change. Skipping notification 'nginx -s reload'

if remove the 9th container everything works (well, only the 9th has VIRTUAL_HOST set.)
This represents the docker-compose file of the 9th container.

version: '2'
services:
  master:
    image: master
    ports:
      - "9050:80"
      - "9022:22"
    environment:
      - VIRTUAL_PORT=9050
      - STAGE_ENV=local
      - VIRTUAL_HOST=mydomain.de

I've noticed that the upstream block of mydomain.de is empty.

I thought the problem could be that compose creates networks for each compose file and nginx-proxy only connects to the default bridge. Therefore i connected nginx-proxy to all networks and used docker-compose restart.
This seems to fix Error running notify command: nginx -s reload, exit status 1 but i still get a Welcome to nginx!-Page.

Sorry i think this is a duplicate of #502 or #438

I had the same issues, and the problem was exactly what you described. I solved it by creating a network called nginx-proxy:

docker create network nginx-proxy

Then I added the following to the bottom of my docker-compose file:

networks:
  default:
    external:
      name: nginx-proxy

Here is my complete docker-compose.yml:

version: '2'

services:

  prod:
    image: ${COMPOSE_PROJECT_NAME}-prod
    container_name: ${COMPOSE_PROJECT_NAME}-prod
    environment:
      - VIRTUAL_HOST=${COMPOSE_PROJECT_NAME}
    volumes:
      - ./prod/${COMPOSE_PROJECT_NAME}/web:/var/www/html/
      - ./prod/${COMPOSE_PROJECT_NAME}/data:/var/lib/mysql
    restart: always


  dev:
    image: ${COMPOSE_PROJECT_NAME}-dev
    container_name: ${COMPOSE_PROJECT_NAME}-dev
    environment:
      - VIRTUAL_HOST=${COMPOSE_PROJECT_NAME}.dev
    volumes:
      - ./dev/${COMPOSE_PROJECT_NAME}/web:/var/www/html
      - ./dev/${COMPOSE_PROJECT_NAME}/data:/var/lib/mysql


  nginx-proxy:
    image: jwilder/nginx-proxy
    container_name: nginx-proxy
    ports:
      - "80:80"
    volumes:
      - /var/run/docker.sock:/tmp/docker.sock:ro


networks:
  default:
    external:
      name: nginx-proxy

Closing as dup of #502
