# docker-cloud-subdomains

A Docker Cloud app which automatically makes other apps in your Docker Cloud account accessible as Heroku-style subdomains (e.g. myapp.example.com).

## Getting started

1. Create a stack on Docker Cloud using this stack file, filling in your Docker Cloud details and setting `DOCKERCLOUD_SUBDOMAINS_DOMAIN` to the domain name you want subdomains to appear on:

        traefik:

          image: traefik

          command: --web

          ports:

            - "80:80"

        updater:

          image: bfirsh/docker-cloud-subdomains

          environment:

            - "DOCKERCLOUD_SUBDOMAINS_DOMAIN=example.com"

            - "DOCKERCLOUD_USER"

            - "DOCKERCLOUD_APIKEY"

          links:

            - traefik

2. Get the address of the traefik service that you have just created in Docker Cloud (something ending with `.svc.dockerapp.io`). Set up a wildcard CNAME on the domain you want to use and point it at the service address.

3. You can now set the label `sh.fir.subdomains.subdomain` and `sh.fir.subdomains.port` on containers in your Docker Cloud apps to to expose ports under a particular subdomain. For example, you might put something like this in your stack file to make port 80 available at `myapp.example.com`:

        web:

           image: oscorp/myapp

           labels:

             - "sh.fir.subdomains.subdomain=myapp"

             - "sh.fir.subdomains.port=80"
