8 years ago I've started seeing this on new instances as well. Edit: I messed up the volumes so /etc/nginx/vhost.d/default wasn't available. Can't reproduce.

8 years ago Hello, I don't understand why the subject is closed. Am I alone to have this issue ?
Thanks for your time.

8 years ago @SuperITMan There are several things that could go wrong to produce that output. Could you show us the nginx configuration generated? docker exec -it nginx cat /etc/nginx/conf.d/default.conf

8 years ago @SuperITMan I was struggling with this earlier too, the key is no servers are inside upstream in /etc/nginx/conf.d/default.conf:36. If you open your 'default.conf' you should see empty upstream configuration. If that's the case remove
-only-exposed from your docker-gen command
-notify-sighup nginx -watch-only-exposed-wait 5s:30s /etc/docker-gen/templates/nginx.tmpl /etc/nginx/conf.d/default.conf

8 years ago If the upstream configuration is empty it's that the "backend" web server doesn't expose any port ?
If it is the case add a --expose port when you start the backend container

8 years ago @JrCs I think you meant --expose port. Some how with -only-exposed docker-gen didn't pickup those with default EXPOSE from Dockerfile. Anyway I'm not really an expert here but removing -only-exposed resolved my issue I had that day

I expose ports with EXPOSE and have not had this problem.

8 years ago @ryneeverett you're right, my bad. I left out EXPOSE in my Dockerfile. Thanks

7 years ago I have the same issue,
I expose the port (8787) in the Dockerfile, I have an expose in the docker-compose.yml but with -only-exposed nothing happens. Without it the server appears in upstream but marked as "down".
Here's the dockerfile:
FROM rocker/hadleyverse
MAINTAINER Stefan Fritsch <fritsch@stat-up.com>
RUN apt-get update \
&& apt-get -y install nginx-light nano procps jags r-cran-rjags \
&& apt-get clean
RUN echo "fr_FR.UTF-8 UTF-8" >> /etc/locale.gen \
&& echo "de_DE.UTF-8 UTF-8" >> /etc/locale.gen \
&& locale-gen
RUN update-locale
EXPOSE 8787
WORKDIR /
CMD ["/init"]and here the docker-compose.yml (nginx&co. run on the same network, and as mentioned apache-php works)
version: '2'
networks:
default:

build: .

Hello,
I'm using your project since one month and I find it awesome ! Thanks for this :)
Yesterday, I decided to use your project as you recommended, in 3 different dockers. Unfortunately, it does not work. Impossible to get my sites in https and when I go on them via http, I obtain an error 503... I precise that this works when I launch only two containers.
This is the error I obtained when letsencrypt should generate the certificate :
For the 3 dockers, I made theses commands :
# Launch nginxdocker run -d -it -p 80:80 -p 443:443 \--name nginx \-v /etc/nginx/conf.d \-v /etc/nginx/vhost.d \-v /usr/share/nginx/html \-v /etc/nginx/certs:/etc/nginx/certs:ro \--restart="always" \nginx# Download templatecurl https://raw.githubusercontent.com/jwilder/nginx-proxy/master/nginx.tmpl > /tmp/templates/nginx.tmpl# Launch docker-gen for nginxdocker run -d \--name nginx-gen \--volumes-from nginx \-v /tmp/templates/nginx.tmpl:/etc/docker-gen/templates/nginx.tmpl:ro \-v /var/run/docker.sock:/tmp/docker.sock:ro \jwilder/docker-gen \-notify-sighup nginx -watch -only-exposed -wait 5s:30s /etc/docker-gen/templates/nginx.tmpl /etc/nginx/conf.d/default.conf# Launch letsencrypt-companiondocker run -it -d \--name nginx-letsencrypt \-e "NGINX_DOCKER_GEN_CONTAINER=nginx-gen" \--volumes-from nginx \-v /etc/nginx/certs:/etc/nginx/certs:rw \-v /var/run/docker.sock:/var/run/docker.sock:ro \jrcs/letsencrypt-nginx-proxy-companionI have no idea of the reason why it does not work but if some one of you has one it would be really cool !
I hope I give all necessary infos :)
