Reverse proxy

A simple reverse proxy

example.com {
    reverse_proxy localhost:5000
}

Only direct certain traffic, such as an api route

example.com {
    root * /var/www
    reverse_proxy /api/* localhost:5000
    file_server
}

Restart the service on failure

This will automatically restart the server after 5 seconds if the exit code when crashing was not 1.

To edit the below file, run

sudo systemctl edit caddy

[Service]
RestartPreventExitStatus=1
Restart=on-failure
RestartSec=5s

    redir https://www.{host}{uri}
}

www.example.com {
}

Remove www

www.example.com {
    redir https://example.com{uri}
