Trouble installing multiple instances on one server

I have been looking for a way to consolidate my ghost blogs onto a single server. Though I am comfortable with Linux and the command line, I am a novice when it comes to servers.

If anyone could offer help in achieving this I would be so grateful!

I have attempted to follow various guides, but all seem to be outdated or somewhat lacking.

I created a shell script to deploy multiple ghost on a single server. Check out this Semi automated multiple ghost deployment in a single server via Shell & Docker

& Let me know if you have any questions
