Mapping incoming domains to the correct application container. Learn what domain routing means in self-hosted deployment and Better-PaaS workflows.

Overview

Mapping incoming domains to the correct application container.

Definition

Mapping incoming domains to the correct application container.

Real-world example

api.example.com → API container, www.example.com → marketing static site, both on one VPS with separate Caddy site blocks.

Common mistake

Two apps claiming the same hostname in the dashboard, causing unpredictable routing.

Better-PaaS in practice

Each domain attachment is tied to one app. Wildcard domains depend on Caddy configuration and DNS setup.

FAQ

Is domain routing only relevant to Better-PaaS?

No. domain routing appears across Docker, cloud platforms, and self-hosted tooling. Better-PaaS exposes the concept in deploy logs, dashboard fields, or docs when it affects your app.
