Resource limits:
- Add cpu_limit (cores) and memory_limit (MB) fields to Stage model
- Pass limits to Docker container via NanoCPUs and Memory in HostConfig
- Add CPU/Memory fields to stage creation form in project detail
- 0 = unlimited (default)
NPM access list:
- Add npm_access_list_id to Settings (global default) and Project (per-project override)
- Per-project overrides global when > 0
- NPM provider passes access_list_id when configuring proxy hosts
- Add GET /api/settings/npm-access-lists endpoint to list NPM access lists
- Add access list picker on NPM settings page (global)
- Add access list ID field on project edit form (per-project)
- DB migrations for all new columns
Replace direct npm.Client usage throughout the codebase with the
proxy.Provider interface, enabling pluggable proxy backends. The
deployer, API layer, and proxy manager now use provider-agnostic
route management (ConfigureRoute/DeleteRoute) instead of NPM-specific
API calls. Adds ProxyRouteID (string) to Instance model and
ProxyProvider setting to Settings, with SQLite migrations for
backward compatibility.
- CRITICAL: Change DNS zones endpoint from GET to POST to avoid
leaking API token in URL query parameters
- HIGH: Add sync.RWMutex to protect dnsProvider field in Server,
Deployer, and proxy Manager against concurrent read/write races
- HIGH: Capture old DNS provider reference synchronously before
launching background cleanup goroutine
- HIGH: Use getDNS()/getDNSProviderLocked() accessors instead of
direct field reads in all DNS operations
Add flexible DNS management to Docker Watcher. By default, wildcard DNS
is assumed (current behavior). When disabled, users can configure a
Cloudflare DNS provider with API token and zone selection. DNS A records
are automatically created/updated/deleted in sync with proxy consumers
(deployed instances and standalone proxies).
- Settings: wildcard_dns toggle, dns_provider, cloudflare credentials
- Cloudflare client: Provider interface with EnsureRecord/DeleteRecord/ListRecords
- DNS lifecycle hooks in deployer and proxy manager (best-effort)
- Settings UI: DNS config section with provider picker, zone selector, test button
- DNS Records page at /dns with filtering, sync status, reconciliation
- Records visible in both wildcard and managed modes
- Cleanup on provider change: removes old records when switching modes
Critical fixes:
- Fix StaleContainer frontend type to match nested backend response shape
- Guard ContainerID[:12] slice against empty/short IDs in ListAllProxies
High-priority fixes:
- Support comma-separated severity/source in event log filtering (IN clause)
- Eliminate N+1 queries in ListAllProxies and FindStaleInstances (pre-load maps)
- Stop leaking internal error messages to API clients (use slog + generic msgs)
Add standalone proxy management:
- Multi-step validation pipeline (DNS, TCP, HTTP) with diagnostic hints
- Proxy lifecycle: create/update/delete via NPM API with SSL auto-assign
- Periodic health monitoring (5min) with event log on status transitions
- Unified /api/proxies/all endpoint merging standalone + managed proxies
- Frontend types and API functions for downstream UI phases
