This article assumes you're already connected to a VM that has rbenv, postgres, and caddy installed, and an /apps folder created.

Steps

• Point the domain/subdomain that you want to use, to the ip address of the server (create an A record).

• Connect to that newly created domain using the VS Code Remote SSH extension (assuming you have an authorised ssh key or password).

  1. ssh root@staging.mydomain.com

• Pull your codebase down from Github into the apps folder. When prompted for credentials, don't enter your normal password. Instead, create a personal token here and enter it when prompted for a password.

  1. cd /apps
     git clone https://github.com/my_repo app_name

• Copy over your environment variables

• Run bundle install, rake db:create and rake db:migrate as usual

• Add passenger to your Gemfile

  1. gem 'passenger'
     bundle install

• Start a new daemonized server with passenger on port 1111 (use a different port if this VM already has other apps that are using that port)

  1. bundle exec passenger start --daemonize -p 1111

• Configure caddy to forward your newly running app (on port 1111) to your subdomain (from step 1)

  1. Open up /etc/caddy/Caddyfile

  2. staging.mydomain.com {
       reverse_proxy localhost:1111
     }

  3. Restart caddy

  4. service caddy restart
