Cloud-Init Config with Docker Letsencrypt Nginx Proxy for Digital Ocean Droplet Creation

Simplify the initial setup process when creating new VPS instances in host providers like Digital Ocean, by copy-pasting the user data provided in cloud-config.yml. Works with droplet creation using Ubuntu 16.04 image.

This config provides:

• Security enhancements (best practices recommended by Digital Ocean):
  • Disabled root login
  • Disabled username/password login
  • Create new user with sudo privileges and no password for ease of use
  • Restrict SSH login to using private key, custom username and custom port
  • Enabled Firewall (only ports 80/443 and custom SSH port are open)
• Automatic service/s launch on boot using /startup.sh
• Automatic SSL support and renewal (IPV6 included) for domains using Letsencrypt Nginx Proxy with Docker
• Latest Docker and Docker-Compose setup
• Docker command aliases
• Git command aliases

Usage

Open cloud-config.yml and do string search and replace as listed in comments.
