Spinning up 20 microservices and PR preview subdomains with HTTP-01 challenges quickly hits Let’s Encrypt rate limits and fails whenever Cloudflare Orange Cloud WAF/CDN proxy is enabled on Flexible SSL.
Switching Dokploy’s embedded Traefik v3 instance to Cloudflare DNS-01 ACME challenges mints a single *.yourdomain.com wildcard certificate that secures unlimited dynamic subdomains automatically without per-subdomain HTTP-01 validation. (DokployHub BP-05)
In this BP-05 runbook on DokployHub, we pair interactive cgroup RAM sizing, browser-persisted checklist gates, and copyable configuration snippets grounded in 2026-11-12 public vendor rate cards.
DokployHub BP-05 Architecture & Hardening Checklist
-
Always set Cloudflare SSL/TLS encryption mode to Full (Strict)—never Flexible—otherwise Cloudflare sends plain HTTP to port 80 while Traefik redirects HTTP to HTTPS, causing an infinite 301 loop.
Confirm gate #1 in your BP-05 staging environment.
-
Create a least-privilege Cloudflare API Token scoped solely to Zone:DNS:Edit on your target zones and inject CF_DNS_API_TOKEN into Dokploy’s Traefik container environment.
Confirm gate #2 in your BP-05 staging environment.
-
Configure certificatesResolvers.letsencrypt.acme.dnsChallenge with provider: cloudflare and explicit recursive resolvers (1.1.1.1:53, 8.8.8.8:53) so local systemd-resolved caches never stall TXT record verification.
Confirm gate #3 in your BP-05 staging environment.
-
Lock permissions on /etc/dokploy/traefik/dynamic/acme.json to chmod 600; Traefik silently refuses to load or renew TLS certificates if acme.json is group- or world-readable.
Confirm gate #4 in your BP-05 staging environment.

How do I restore real visitor IP addresses inside Next.js or Go behind Cloudflare + Traefik? (DokployHub BP-05)
Configure entryPoints.websecure.forwardedHeaders.trustedIPs in Traefik with Cloudflare’s published IPv4/IPv6 CIDR ranges so Traefik trusts CF-Connecting-IP and X-Forwarded-For without letting attackers spoof headers directly against your VPS IP.
Why does Traefik serve the default self-signed certificate after adding a new wildcard router? (DokployHub BP-05)
Double-check two things: (1) acme.json has exact 0600 permissions, and (2) your router specifies tls.domains[0].main: "yourdomain.com" and sans: ["*.yourdomain.com"] using the DNS-01 resolver rather than HTTP-01.
