Stop Sprinkling API Keys Everywhere: My Self-Hosted NewAPI Relay Station

Fri, 10 Jul 2026 15:30:00 +0800

TL;DR

NewAPI is not a free-model trick and it is not a mysterious proxy. In my setup, it is the front desk for AI usage: every app talks to one endpoint, while the gateway routes requests to authorized upstream providers and handles tokens, quotas, groups, model limits, logs, and usage accounting. For a personal deployment, the big win is not “one more dashboard”; it is no longer scattering upstream keys across every client, script, and agent.

This post explains why I wanted a self-hosted model relay, what people usually misunderstand, how to deploy a minimal Docker Compose version, why I add persistent storage, and how to use one-click scripts for Windows 11, Ubuntu 26.04, and macOS 26. It also includes an agent-driven setup prompt with strict boundaries. No private address, complete machine name, private domain, or real secret is included.

Docker Images, No More Begging: Build Your Own 13 GB Private Registry From Scratch

Fri, 26 Jun 2026 12:30:00 +0800

TL;DR

My home server runs a single registry:2 container that currently holds 13 GB of cached blobs across 95 repositories. Every NAS, Proxmox node, Mac, and Windows machine on my LAN pulls through it. A cold start of alpine:3.19 finishes in under a second, with zero traffic going out to the public Docker Hub.

This isn’t a one-line “install Docker and run a container” tutorial. I’ll show you the production-grade deployment script I actually run, walk through the Docker v2 auth flow, and call out the four reverse-proxy pitfalls that turn every docker login into a 401 mystery. You’ll leave able to: ① bring up an authenticated registry in 10 minutes; ② explain why the WWW-Authenticate header is sacred; ③ describe the whole thing to a non-technical family member without losing accuracy.
