Steps to install Discourse in a VM using Multipass

install-discourse-in-multipass-vm.sh

## Multipass on macOS
# Download and install: open https://multipass.run/download/macos

## Create Discourse VM and open shell
multipass launch --disk 8G --memory 4G --name discourse-server && multipass shell discourse-server

## Install NVM and Node 18 LTS
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.5/install.sh | bash && source ~/.bashrc &&  nvm install v18.18.2

##  Install yarn
npm -g install yarn

##  Run the Discourse install script:
cd ~ && bash <(wget -qO- https://raw.githubusercontent.com/discourse/install-rails/master/linux)

##  Clone the discourse repo
cd ~ && git clone https://github.com/discourse/discourse.git ~/discourse

##  Install everything
cd ~/discourse && source ~/.bashrc && bundle install && yarn install

## DB migrate
cd ~/discourse  && bin/rails db:create  && bin/rails db:migrate  && RAILS_ENV=test bin/rails db:create db:migrate

##  Run!
cd ~/discourse && bin/ember-cli -u

Here is how to find the IP for the Discourse VM:

echo "http://$(multipass info discourse-server |grep IPv4 |awk -F':' '{print $NF}'| tr -d ' '):4200"

You should perhaps not have the delete and purge command in the same script :)

Haha, true... I put that here instead:

## Delete and purge multipass instance when not needed anymore
multipass stop discourse-server &&  multipass delete discourse-server && multipass purge
