We want to mirror all basic configurations and updates applied to a master Ubuntu droplet to other droplets.
They all use Apache, ProFTP, Webmin, MySQL, UFW, fail2ban, SSH, Docker.
Every install has specific services installed, as CRM, Web, ERP etc.
Cluster is for load, volumes are not mentioned to share system files.
Thanks for hints and ideas.
