Subdomain Manager

Subdomain Manager (Cloudflare) Calagopus extension for managing server subdomains in Cloudflare. This extension includes: • Backend extension: backend-extensions/devluxxycloudflaresubdomain • Frontend extension: frontend/extensions/devluxxycloudflaresubdomain Features • Assign one managed subdomain per server • Cloudflare provider + managed zone/domain configuration • Regex blacklist rules for reserved labels • Alias rules for mapping allocation IP/IP alias to DNS target • Record templates (including SRV support) • Safe cleanup on assignment removal (including fallback cleanup for previously untracked records) • Allocation picker in server UI • Server type mapping in server UI: • Minecraft -> SRV • Web -> A Minecraft SRV Behavior For Minecraft server type, SRV names are generated with: minecraft.tcp. Example: • Label: sus • Base domain: luxxy.pro • Resulting SRV name: minecraft.tcp.sus.luxxy.pro SRV port defaults to the selected allocation port unless explicitly overridden by a record template. Cloudflare Token Requirements Use a scoped API token with: • Zone.DNS:Edit • Zone.Zone:Read On the zones you want to manage. Installation / Wiring This extension is already wired in this repo through: • backend-extensions/internal-list/src/lib.rs • frontend/extensions/devluxxycloudflaresubdomain/src/index.ts If you are setting up from scratch: 1. Ensure backend extension folder exists in backend-extensions/. 2. Ensure frontend extension folder exists in frontend/extensions/. 3. Ensure backend extension is included in backend-extensions/internal-list. 4. Run extension migrations. 5. Rebuild/restart panel backend and frontend. Database Migrations Migration path: database/extension-migrations/devluxxycloudflaresubdomain/20260402190000subdomainmanagerinit/ Includes tables for: • providers • managed domains • blacklist rules • alias rules • record templates • assignments • generated records • audit events UI Locations • Admin configuration is available via the extension card Configure action. • Server assignment page: • Server -> Subdomain Effective Permissions Used The extension currently uses built-in permissions: • Admin routes: • settings.read • settings.update • Server routes: • allocations.read • allocations.update Troubleshooting 1) cloudflare ... Authentication error • Verify token is valid and not expired. • Verify token has Zone.DNS Edit + Zone.Zone Read. • Verify token has access to the specific zone. 2) invalid zone identifier / zone verification failure • Ensure Zone ID is the Cloudflare zone UUID (32 hex chars), not zone name. 3) SRV target must be a hostname • SRV target cannot be an IP. • Use a hostname in alias/template target (for example n4.example.com). 4) Remove clicked but DNS record remained • Current cleanup includes fallback deletion by name + type in Cloudflare for records that were not previously tracked. • Retry remove once after updating extension. 5) Wrong SRV port • Ensure allocation selected in server page is correct. • SRV now defaults to selected allocation port when template port is empty.
