I’ve set up what should be a vanilla Docker-based Discourse install (except that I’ve imported an existing database from another, non-Docker install). Things mostly work, but OAuth via github (as well as twitter) fails with a `message=redirect_uri_mismatch` error. Inspecting the actual packets that are being sent over, I see this in the url:

```
redirect_uri=http%3A%2F%2Flocalhost%3A6080%2Fauth%2Fgithub%2Fcallback

```

So that explains that error message. What can I do to make Discourse use its real url (`discuss.codemirror.net` in this case)?

Edit: Forgot to mention, the container isn’t directly binding port 80/443, but being proxied through an nginx, since the host serves other sites as well.
