Custom Domain Setup for Worker - DNS Configuration with External DNS Provider
Hi ,
I need help setting up a custom domain for my Cloudflare Worker, but with a constraint: our main domain and DNS must remain managed with our external DNS provider.
Current Setup:
Worker name: my-worker
Desired custom domain pattern: *.staging.example.com
Goal: Route https://api.staging.example.com to my worker
Constraint: Main domain example.com and all DNS records must stay with external DNS provider (AWS Route 53)
Current plan: [Free/Pro/Business]
Questions:
Can I configure a Cloudflare Worker custom domain WITHOUT transferring my domain or DNS management to Cloudflare?
What DNS records do I need to create in my external DNS provider to point a subdomain to my Cloudflare Worker?
Is it possible to use Cloudflare Workers with custom domains while keeping the primary domain with external DNS?
Do I need to use CNAME records pointing to my workers.dev subdomain, or is there another approach?
What SSL certificate requirements exist when the domain DNS is managed outside Cloudflare?
Would upgrading to the Business plan and using the Partial DNS feature help with this setup?
Specifically:
Does Partial DNS allow better integration with external DNS providers?
Would Partial DNS solve custom domain issues when the main domain stays external?
Are there DNS delegation benefits with Partial DNS for this use case?
Important: We cannot move our domain or DNS management away from our current provider, but want to route specific subdomains to Cloudflare Workers.
