Custom domain name and configure HTTPS

This tutorial will demonstrate the core capabilities of Rainbond gateway management:

• Out of the box: No additional configuration required, use directly.
• Automatic domain name resolution: Supports dynamic binding of custom domain names.
• Multi-protocol support: Simultaneously supports HTTP/HTTPS and WebSocket protocols

Prerequisites

• Completed Rainbond Quick Installation.

Bind a custom domain name

• Wildcard domain name support: *.example.com matches all subdomains.
• Multi-tenant isolation: Different teams have independent domain name spaces.

🧩 Operation process

1. Deploy components using container images

   1. Enter the target team view and create a new application.
   2. Select Build from Image ➡️ Container.
      • Customize the application name.
      • Image address：registry.cn-hangzhou.aliyuncs.com/goodrain/nginx:alpine

2. Bind a custom domain name

   1. Enter the application view ➡️ Gateway management ➡️ Add route.
      • Domain name：demo.example.rainbond.com.
      • Select the component created above.
   2. Resolve the domain name demo.example.rainbond.com to the Rainbond gateway IP, such as: 192.168.1.1.
   3. Access the custom domain name, expected result: Welcome to nginx!.
