Introduction

This is assorted notes on what could go into the MakerFLOSS lab

Requirements

• A space to experiment with new software
• A place where software could be "test run" for some time
• A place where errors are not causing IP loss
  • even if errors are real big !!

More details

• Firewalled off from the production network
• Accessible from outside
• Potential for exposing services externally

Constraints

• Cost conscious
• Support constant change

Proposals

Short term

A VPS in a (European) cloud with one public IP

Midterm

Complement the VPS with some local hardware:

• Firewall with zones (VLANs, DNS/DHCP)
• Netbird access to services in Lab
• Switching infrastructure
• A primary "stable" Proxmox host
• A secondary experimentation machine
• A backup server
• Tunnel for external access via VPS public IP

Basic Services in Lab

• Git: Forgejo
• ...

Long term

replace VPS with a direct IP pinhole access

replace the "stable" FLOSS services running on VPS with modules runing on "stable" machine locally
