docker-compose nginx volumes not mounted -

i have docker-compose.yml nginx in when running volumes not found inside nginx container. dockerfile works fine in setup , src dir exists, dont understand why doesnt work here?

nginx says:

nginx_1 | 2015/06/04 09:33:32 [error] 13#0: *1 open() "/var/www/web/index.html" failed (2: no such file or directory), client: 172.17.42.1, server: , request: "get /index.html http/1.1", host: "localhost:8085"

tree:

. ├── code ├── docker-compose.yml ├── logs ├── nginx └── readme.md 

the docker-compose.yml

nginx:     build: nginx/     volumes:         - code/dist:/var/www     ports:         - 8085:80 

the dockerfile:

from ubuntu:14.04  env debian_frontend noninteractive  run apt-get update && apt-get install -y \     nginx  run echo "\ndaemon off;" >> /etc/nginx/nginx.conf add vhost.conf /etc/nginx/sites-enabled/default  add start.sh /start.sh expose 80  entrypoint ["/start.sh"] 

update

when rename nginx othernginx in docker-compose.yml works ??
why that?
seems interferes other container build, docker-compose not seperate containers between different docker-compose.yml?

looking @ error, nginx trying fetch index.html /var/www/web/index.html. however, mounting code var/www. figure container nginx might using earlier build uses /var/www/web/ directory , changing container name forced rebuild. docker-compose --build should force rebuild.
