Control plane deployment

Run cargo run -p arkflow-server --bin arkflow-server as the Hub and start each compute node with health_check.hub_url, node_id, and node_token. Then build the console with cd console && npm ci && npm run build, and serve console/dist from a protected reverse proxy. The development Vite server proxies /api and /metrics to 127.0.0.1:8080; production should preserve the same-origin paths and set VITE_API_BASE only when the API prefix differs. Set VITE_API_TOKEN only in a controlled build environment when the ArkFlow listener has an operator credential configured. The compatibility credential may be a raw token (admin) or principal|role|secret, for example readonly|viewer|viewer-secret; viewer credentials can read resources and audit history but cannot mutate Streams, nodes, or rollouts.

The included console/Dockerfile builds static assets and serves them through Nginx. Its /api/ and /metrics locations proxy to an arkflow-hub:8080 service; deploy it on a private network with TLS and an authentication layer. Do not expose the API or the token-bearing console directly to the public internet. The ArkFlow default bind address is local-only.

Migration from the health-centric console

The old UI treated the backend as a health and aggregate-stream monitor. The resource-oriented console uses /api/v1/system, /nodes, /streams, /operations, /events, /configuration, and /components. Lifecycle requests are asynchronous and must be polled by operation ID. Existing /health, /readiness, /liveness, /metrics, /status, and /config* routes remain as compatibility aliases, but new integrations should use the resource endpoints. Configuration versions, operations, audit records, and bounded event history are durable in Hub mode. Rollouts are available under /api/v1/rollouts; use the action endpoint to pause, resume, cancel, or create a rollback. The authenticated /api/v1/events/stream SSE endpoint supports filters and Last-Event-ID; clients must reload REST snapshots after a resync event.

For reverse proxies, preserve Authorization, X-Correlation-ID, and the SSE text/event-stream response without buffering. Do not put credentials in query parameters.
