My application already runs inside Docker, and the stack is working fine. I now need the live traffic moved to a new production subdomain (for example, [login to view URL]) while the root domain’s front page simply points visitors to that subdomain. Here’s what the job involves: • The server is Docker-based; all compose files are in place, so you’ll work within that setup. • DNS access is ready, and SSL must remain intact. • I’d like the switch handled with no downtime, followed by a quick verification that everything resolves correctly. Deliverables 1. Update DNS and Docker-side reverse-proxy rules so the service answers on the new production subdomain. 2. Redirect or relink the existing root domain’s front page to the subdomain. 3. Supply a brief summary of the changes for future reference. If you have solid Docker networking experience, let me know your timeline and any questions you might have.

Repointing a Dockerized application to a production subdomain without interrupting live traffic is all about getting the order of changes right. I'll configure the new subdomain and SSL first, update the Docker reverse proxy (Nginx/Traefik/Caddy) to serve both domains during the transition, verify the application is responding correctly, and only then redirect the root domain to the new production URL. This approach keeps the migration seamless while avoiding downtime or certificate issues. Once complete, I'll verify DNS, HTTPS, and routing end-to-end and provide a concise summary of every change. I can start immediately.

Hi there, You've got a working Docker stack and just need live traffic moved to a new production subdomain with zero downtime while SSL stays intact — I'll sort the DNS and reverse-proxy side and verify everything resolves cleanly. What I'll do: ✅ Update DNS records and Docker reverse-proxy rules so the service answers on the new production subdomain ✅ Redirect/relink the root domain's front page to the subdomain without breaking existing connections ✅ Test SSL and host-header routing before switching, then confirm the cutover end-to-end and leave you a short change summary ✅ Docker / Docker Compose networking and reverse proxies ✅ DNS management (A, CNAME, TTL) and SSL certificates ✅ Ubuntu/Linux server administration ✅ Zero-downtime traffic moves ✅ Microsoft® Certified: MCSA | MCSE | MCT ✅ 300+ projects delivered, 280+ five-star reviews Why me: I've done these cutovers many times — usually in minutes, not hours. Quick question: do you already have a reverse proxy (nginx/traefik) in front of the Docker service, or should I handle that part too? I can deliver this in 1 day for $30 and start right now — just share the exact subdomain you want to use.

Hi, I understand you need a seamless migration of your Docker-based app to a subdomain without downtime, keeping SSL intact and ensuring the root domain redirects cleanly. I’ve done this before with a similar setup where we moved a SaaS app to a subdomain while maintaining zero downtime and automating SSL renewal through Traefik in Docker. I’d approach this using Docker Compose with Traefik as the reverse proxy, since it handles SSL termination and subdomain routing automatically. The biggest improvement will come from testing the new config in staging first to catch any DNS propagation delays. I’ll document every change and verify the setup before flipping the DNS switch, so you can roll back if anything goes wrong. This ensures your users experience no disruption while the infrastructure stays maintainable and secure. I can start right now. Thanks, Denis.

Since your Docker stack is already running, this is mostly a DNS and reverse proxy task. I'll point the subdomain's A record to your server, set up an Nginx or Traefik vhost, and issue a fresh SSL cert with Certbot so traffic switches over clean. Can start today, live within a few hours. The budget and timeline here are based on the post, I'll confirm both once I see your current DNS setup. Want to jump on a quick call?

Hi there. I see you need to redirect live traffic to a production subdomain for your Dockerized application. I've handled DNS configuration for web applications that required pointing domains to specific environments. My web development background means I understand how traffic routing works alongside application architecture, which helps ensure the cutover happens smoothly without disrupting your running stack. - Review your current DNS records and identify the exact changes needed for the subdomain redirect. - Configure the appropriate A/CNAME records to point traffic to your production environment. - Verify propagation and confirm live traffic reaches the correct endpoint. Is the subdomain already created in your DNS provider, or does that need to be set up as part of this task? I can start on this right away and keep all communication through Freelancer messages. This type of DNS work typically moves quickly once I have access to your domain registrar panel. Best regards, David R.

Greetings, The thing that decides whether this is truly zero-downtime is TTL, and it has to happen before the switch. If your current records are sitting on a long TTL, some resolvers keep pointing at the old setup for hours after the change and rollback is slow. So I'd drop the TTL first, let it propagate, then do the cutover and get the certificate for the new subdomain issued and verified while the old one is still serving traffic, so the proxy only ever flips onto a hostname that already has valid SSL. Docker, Nginx and DNS are my day-to-day work there's a containerised deployment in my profile portfolio, and I'm AWS certified. Timeline: about two hours of actual work, but the TTL needs to be lowered a few hours ahead, so the sensible plan is prep today and cut over tomorrow. You'll get the change summary the same day. Send me your compose file and your current reverse-proxy config and I'll tell you exactly what I'd change before touching anything.

Hello, Your Docker application can be moved to the production subdomain with updated DNS, reverse-proxy routing, SSL validation, and a clean root-domain redirect—without service interruption. I’ve handled similar Ubuntu, Docker, Nginx, Cloudflare DNS, and SSL deployments for multiple production SaaS platforms. The switch can be completed within a few hours, followed by DNS, HTTPS, redirect, container-network, and endpoint checks. I’ll also provide a clear change summary. Which reverse proxy are you using—Nginx, Traefik, or Caddy? Is DNS managed through Cloudflare? Best Regards Hasan
