nginx-proxy
|
||||
===========
|
||||
nginx-proxy sets up a container running nginx and [docker-gen][1]. docker-gen generate reverse proxy configs for nginx and reloads nginx when containers they are started and stop.
|
||||
|
||||
Automated nginx proxy for Docker containers using docker-gen
|
||||
See [Automated Nginx Reverse Proxy for Docker][2] for why you might want to use this.
|
||||
|
||||
To run it:
|
||||
|
||||
$ docker run -d -p 80:80 -v /var/run/docker.sock:/tmp/docker.sock -t jwilder/nginx-proxy
|
||||
|
||||
Then start any containers you want proxied with an env var VIRTUAL_HOST=subdomain.youdomain.com
|
||||
|
||||
$ docker run -e VIRTUAL_HOST=foo.bar.com -t ...
|
||||
|
||||
Provided your DNS is setup to forward foo.bar.com to the a host running nginx-proxy, the request will be routed to a container with the VIRTUAL_HOST env var set.
