Nextcloud Docker Hosting Platform

Project Overview

I built a Docker-based proof of concept for managing multiple isolated Nextcloud instances—automated create/update/backup scripts and an Nginx reverse proxy. Each customer got their own Docker Compose stack, with container mountpoints on NAS storage. TLS used Let’s Encrypt by default, or the customer’s custom wildcard certificate when they had one. After the core automation worked, the return on investment for turning it into a hosted product was judged too low, and the project was abandoned.

What I Was Building Toward

The first-stage objective was a working platform where management scripts abstracted the actual Docker commands. Operators who did not have Docker experience could still assist customers during downtime when a Docker engineer was unavailable.

Beyond that, the idea was multi-tenant hosting without manual snowflake instances:

• Isolated Docker Compose stacks per customer (own MySQL/Redis and app containers)
• Data volumes on NAS mountpoints
• TLS via Let’s Encrypt, or a customer-supplied wildcard certificate when available
• Centralized backup and health-check scripts
• Canary update flow before promoting changes
• Shared reverse proxy with per-domain routing

Layout roughly looked like configuration, helper scripts, Nginx/SSL material, per-instance Compose files, and templates under a single host tree.

Why It Stopped

The project remained a POC. Once the core automation surface existed, continuing toward a full hosted service did not clear the ROI bar, so work stopped before it became a product I operated for customers. Status is archived: useful learning in container isolation, certificate handling, and multi-instance ops scripts—not a finished hosting business.

What I Kept From It

• Comfort with Docker Compose multi-service stacks and network/volume isolation
• Scripted instance lifecycle (create, backup, update, health-check, canary)
• Preference for automation that reduces manual host drift—even when the product itself does not ship
