Nginx Proxy Manager

Node.js backend generating and reloading nginx configs, a Vue frontend for managing proxy hosts/certificates, and a SQLite database storing proxy host definitions and cert metadata.

By design it's a single instance managing one nginx process's configuration — it isn't meant to be horizontally scaled, since having multiple instances editing the same proxy config would conflict. It scales in the sense of handling many proxied domains from one instance, not in the sense of adding replicas.

Runs as a single pod with a persistent volume for its SQLite data and Let's Encrypt certificate storage; mirror the official image via mirror.gcr.io. On Nexlayer, note that inbound routing is already handled by the platform's own ingress, so NPM is more relevant for self-hosted homelab-style deployments than as an in-platform component.
