Selt hosted ghost

I want to run a few different sites is it possible to have one instance of ghost handling two different domains or do I install one instance for each domain?

I’m on the paid version of ghost.org now but its simply not worth the cost due to limitations. $29/mo for a simple newsletter is a rip off.

One instance of Ghost is one website – so, to handle multiple sites with multiple domains, you would need multiple instances of Ghost (that counts for all managed Ghost hosting providers as well as self-hosted installations).

thanks. setting up docker now.
