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 stopped.
|
|
|
|
See [Automated Nginx Reverse Proxy for Docker][2] for why you might want to use this.
|
|
|
|
### Usage
|
|
|
|
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.
|
|
|
|
### Multiple Ports
|
|
|
|
If your container exposes multiple ports, nginx-proxy will default to the service running on port 80. If you need to specify a different port, you can set a VIRTUAL_PORT env var to select a different one. If your container only exposes one port and it has a VIRTUAL_HOST env var set, that port will be selected.
