Can't specify a subpath

[trostli]

In version 5, I was able to set my URL in Ghost config to a subpath of my main app: https://example.com/blog

While the A record and actual ghost blog live at https://blog.example.com`, I used a reverse proxy to have to blog be accesible via https://example.com/blog.

Its not clear if thats possible with v6 with Docker setup. In the instruction I only see a way to set the root Domain. Is there a way to do this?

Ah I figured this out! I manually edited docker-compose.yml to add a subpath in the url field under the main ghost service. I think it would be handy to add an optional ENV var for this.
