Multisite Discourse separate folder structure of each instance - 2018

Welcome to another episode of request help by Seasiri.

I know there are many multisite installation attempted and asked as I screen through it for whole day.
I want to make how-to setting up multisite with step by step after I get this to work. Therefore, let’s get start into the problem.

I try to setup multisite with separate folder structure for each site.

  1. I use this app.yml with my own detail setup. (Multiple docker containers for multiple Discourse forums?)
  2. Upon running i receive this error:

Ensuring launcher is up to date
Fetching origin
Launcher is up-to-date
cd /pups && git pull && /pups/bin/pups --stdin
/usr/bin/docker: invalid reference format.
See ‘/usr/bin/docker run --help’.
cat: cids/app_bootstrap.cid: No such file or directory
“docker rm” requires at least 1 argument.
See ‘docker rm --help’.
Usage: docker rm [OPTIONS] CONTAINER [CONTAINER…] [flags]
Remove one or more containers
rm: cannot remove ‘cids/app_bootstrap.cid’: No such file or directory
** FAILED TO BOOTSTRAP ** please scroll up and look for earlier error messages, there may be more than one

Are there any good tutorial or how to run the multisite discourse?
This is what I want to archive.

This is the domain I want each separate discourse to point to.

Best,
Sea
