Hosting

Install nginx on your server. Then edit the configuration to map port 80 (or any other port) to 8000

sudo vi /etc/nginx/sites-available/default

Change it to this

server {
    listen 80;

    server_name localhost;

    location / {
        proxy_pass http://localhost:8000;
    }
}

Authentication

If you need to apply basic HTTP authentication, you can set user name and password through environment variables:

BASIC_AUTH_USER=user BASIC_AUTH_PWD=SecretPassword

You can also enable basic http authentication with user name and password on nginx to prevent unauthorized users from accessing your cronjobs. Refer this.
