Easy SSL Setup for Profit Trailer using Caddy 2

# meant to go with Ubuntu 18.04.

$ echo "deb [trusted=yes] https://apt.fury.io/caddy/ /" \
    | sudo tee -a /etc/apt/sources.list.d/caddy-fury.list
$ sudo apt update
$ sudo apt install caddy

# start/restart commands

$ sudo systemctl daemon-reload
$ sudo systemctl enable caddy
$ sudo systemctl start caddy

# Caddyfile wherever you want it

$ cd /opt
$ nano Caddyfile

# This is your caddyfile: 

{
 email yourmail@forletsencrypt.org
}

yoursub.dom.ain {
  reverse_proxy /long* http://localhost:7010
  reverse_proxy /short* http://localhost:7020
}

# ammend ports and folder names as need, remember to add the folder to PT settings as folder prefix.

# save the file and reload caddy from the folder where the file is

$ caddy reload

# First reload will take a bit to fetch the SSL cert, watch the output for errors.
# Hint: Caddy doesn't have a fixed config file location. It writes the config into caddy while reloading so you need to reload from folder where your config file is.
