custom configuration via docker-compose.yml

[b3nk3]

Hi,

I am a bit unsure on how to implement this:

FROM jwilder/nginx-proxy
RUN { \
      echo 'server_tokens off;'; \
      echo 'client_max_body_size 100m;'; \
    } > /etc/nginx/conf.d/my_proxy.conf

In my compose file? I don't necesserly need a full custom config file, only the client_max_body_size part

One way is to put that in a local Dockerfile next to your docker-compose.yml and use build: . in docker-compose.yml. Then do docker-compose build before up.

I see, i don't really want to mess about with own dockerfiles...

So how would I add my custom config file? As a volume?
/host/path/to/custom/nginx.conf:/etc/nginx/conf.d/my_proxy.conf

[wader]

Hmm yeah that i think should work too... actually there is a example for doing that in README.md

[b3nk3]

I know, but that involves a dockerfile as well. I just want to keep it the simplest, compose only.

Sorry i was referring to the example in READMe.md for using a volume for custom config

docker run -d -p 80:80 -p 443:443 -v /path/to/my_proxy.conf:/etc/nginx/conf.d/my_proxy.conf:ro -v /var/run/docker.sock:/tmp/docker.sock:ro jwilder/nginx-proxy

For compose that should just be a - volumes: line.

Right, added my .conf as a volume, it works but then I get this error:

[emerg] 11#11: "daemon" directive is not allowed here in /etc/nginx/conf.d/nginx.conf:1

if i delete the daemon it goes to the user and so on....
Any clues?

Hmm how does /etc/nginx/conf.d/nginx.conf look? note that /etc/nginx/nginx.conf has this:

http {
    ... cut ...
    include /etc/nginx/conf.d/*.conf;
}
daemon off;

So if there is a daemon directive in /etc/nginx/conf.d/nginx.conf is will be inside `http { ... } which would give that error. Try strip out all global config from your config and only keep the http stuff if that is possible.

Hey,
How do you do this ? I want to do the same.

Thanks
