Nginx TLS SNI routing, based on subdomain pattern

Nginx can be configured to route to a backend, based on the server's domain name, which is included in the SSL/TLS handshake (Server Name Indication, SNI).
This works for http upstream servers, but also for other protocols, that can be secured with TLS.

prerequisites

• at least nginx 1.15.9 to use variables in ssl_certificate and ssl_certificate_key.
• check nginx -V for the following:

  ...
  TLS SNI support enabled

Proxmox PVE Host Config Backup Script

This script can be used to backup essential configuration files from the Proxmox Virtual Enivronment (PVE) host.

The script will create backups using tar with specified backup prefix and date and time stamp in the file name. Script will also delete backups that are older then number of days specified.

Create backup script file

To create backup script that will be executed every day we can create backup script in /etc/cron.daily/ folder. We need to make it writeable by root (creator) only, but readable and executable by everyone:

touch /etc/cron.daily/pvehost-backup

Generate ssl certificates with Subject Alt Names on OSX
=======================================================

Open `ssl.conf` in a text editor.

Edit the domain(s) listed under the `[alt_names]` section so that they match the local domain name you want to use for your project, e.g. 

    DNS.1   = my-project.dev
    
Additional FQDNs can be added if required:
