Config.url for storage and frontend


It’s my first time using Ghost CMS.
I use it as a headless REST-API for the content of subpages.

  • Newest Docker-Version (installed yesterday) - ghost:4.3.2
  • What’s your URL?
    → Backend:
    → Frontend:

I changed the frontend-url with docker-compose exec ghost config url to the frontend-url (dev.)
But now, the images in posts and pages are not shown.

Is there any possibility to set two different URLs?
One for the frontend/preview/“View Site” and one for the storage (in my case the ghost content directory).

Thanks in advance for your help
