Instructions for Oracle Cloud

[ddavness]

If you're deploying this on Oracle Cloud, we'll not be able to use ufw. You'll need to install firewalld instead. As such, run these commands before the setup:

sudo apt update
sudo apt install firewalld -y

# Port 22 (SSH) is already open to us by default
for PORT in 25/tcp 53/tcp 53/udp 80/tcp 443/tcp 465/tcp 587/tcp 993/tcp 995/tcp 4190/tcp
do
    sudo firewall-cmd --zone=public --permanent --add-port=$PORT
done

sudo firewall-cmd --reload

The run the setup as usual.
