Setup a reverse proxy server

In this step we will seutp Caddy as a proxy server, install Caddy Server with:

APT Based OS RPM Based OS

sudo curl -1sLf 'https://dl.cloudsmith.io/public/caddy/stable/gpg.key' | sudo gpg --dearmor -o /usr/share/keyrings/caddy-stable-archive-keyring.gpg
sudo curl -1sLf 'https://dl.cloudsmith.io/public/caddy/stable/debian.deb.txt' | sudo tee /etc/apt/sources.list.d/caddy-stable.list
sudo apt update
sudo apt install -y caddy
sudo ufw allow 80
sudo ufw allow 443
sudo ufw reload
sudo systemctl enable caddy --now

sudo dnf install -y 'dnf-command(copr)'
sudo dnf copr enable @caddy/caddy
sudo dnf install -y caddy
sudo firewall-cmd --permanent --zone=public --add-service=http
sudo firewall-cmd --permanent --zone=public --add-service=https
sudo firewall-cmd --reload
sudo systemctl enable caddy --now

Once installed Caddy will create the configuration file in /etc/caddy/Caddyfile, you can configure Caddy as reverse proxy with the following configuration:

:80 {
  reverse_proxy localhost:8080
}

With this setup the server server will recibe the request and past then to the wsgi in the backgroud.
