Fix K8s sidecar registration and stale cluster topology broadcast - #512
Merged
Merged
Conversation
Two coupled defects broke the Kubernetes metrics path and left the Cluster Topology view stale: 1. Sidecar registration (regressed in #379): the register handler required a pre-existing metricsServerMap entry, but in K8s the orchestrator never spawns collectors, so externally-managed sidecars were always rejected (401/404). Registration is now allowed when the nodeId belongs to the discovered cluster topology, and the sidecar's entry is created on first register. Scoped to K8s so the strict no-entry gate is preserved for spawned (Web/Electron) collectors. Sidecars authenticate with a shared ORCHESTRATOR_KEY provisioned to both the orchestrator and every sidecar via a Kubernetes Secret; resolveCollectorKey falls back to that key only in K8s mode. 2. Stale topology broadcast (regressed in #279): refreshAllClusterRegistries broadcast the registry every 30s but no longer re-discovered topology, so clients kept the connect-time snapshot. It now re-discovers each tracked cluster through a live client belonging to that cluster before broadcasting. Adds tests covering registry refresh on topology change and that reconcile acts on the refreshed topology. Updates the K8s example manifests (Secret + env wiring) and deployment docs.

Build connectionIdsByCluster once and use it both to pick a client for topology re-discovery and to target the broadcast, instead of making a second pass over `clients` for a separate clientByCluster map. The client is reached via clients.get(connectionId).client, keyed by the same connectionIds already grouped for the broadcast. No behavior change. Signed-off-by: ravjotb <ravjot.brar@improving.com>
app.yaml defined a Secret named valkey-admin-orchestrator-key with a committed placeholder value. Applying it after creating a real random Secret of the same name would overwrite the real key with the public placeholder, leaving the orchestrator and every sidecar signing with a known key (CWE-798). An attacker able to reach the orchestrator could then register a known cluster node with an attacker-controlled metrics URI. Remove the Secret definition from app.yaml — the manifest now only references the Secret by name. The key is created out-of-band with a user-supplied random value (kubectl create secret ...), so apply can never clobber it. Docs updated to state the Secret is created first and is intentionally not defined in the manifest. Signed-off-by: ravjotb <ravjot.brar@improving.com>

- Carry per-cluster connection metadata forward on refresh instead of reverting to initialConnectionDetails: updateClusterNodeRegistry now takes a required NodeInfo, and the refresh loop sources it from an existing node of that cluster. Narrow discoverCluster to NodeInfo and drop the redundant getClusterTopology wrapper. - Re-discover preconfigured clusters (K8s sidecars, headless Web) through the initial client each cycle, since they have no entry in `clients`; otherwise a node scaled in after boot never registers until a UI session opens. Await the boot-time K8s discovery. - Bound each cluster's re-discovery with a timeout so one hung CLUSTER SLOTS can't stall the whole broadcast loop. - examples/k8s/valkey-statefulset.yaml: give the inline metrics sidecar the ORCHESTRATOR_KEY it needs, and document that the Secret must exist and the cluster must be formed before the sidecars start. - Document that the shared orchestrator key is a cluster-scoped credential and that the K8s metrics host is not pinned to loopback. - Rework the topology-refresh test to exercise real discovery via a fake CLUSTER SLOTS client; drop a tautological reconcile test. Signed-off-by: ravjotb <ravjot.brar@improving.com>
updateClusterNodeRegistry keyed the registry on the clusterId derived from CLUSTER SLOTS (the first slot range's primary). That id changes on failover/resharding, so re-discovering an existing cluster could write a new entry under a different id and leave the old one orphaned in the map. Add an optional clusterId override: the refresh loop passes the cluster's existing id so the entry is overwritten in place, while boot-time first discovery still falls back to the derived id. Adds a test covering the changed-derived-id case. Signed-off-by: ravjotb <ravjot.brar@improving.com>
The branch's new behavior was largely untested, and the K8s-gated paths are unreachable from the default test suite because isKubernetes is a module-load constant. - orchestrator-k8s-register.test.ts sets DEPLOYMENT_MODE=K8 before import to cover the shared-key path: resolveCollectorKey falls back to ORCHESTRATOR_KEY (and still prefers a minted per-node key), and handleRegister admits a signed sidecar for a known cluster node with no pre-existing entry while rejecting unknown nodes and wrong-key signatures. - Extract resolveClusterRefreshTarget (the refresh client/nodeInfo choice) so it is unit-testable: a user-connected cluster carries its own node metadata forward; a preconfigured/headless cluster falls back to the initial client + initialConnectionDetails. Covered in metrics-orchestrator (user path / skip) and topology-refresh-preconfigured (fallback path). getInitialClient is routed via internals so the fallback is mockable; no behavior change.

Use one timestamp for the body and signature.
createOrchestratorAuthCredential signs the timestamp from signRegister(). handleRegister verifies against the request body's timestamp. If the separate Date.now() calls cross a millisecond boundary, the valid-registration test fails authentication. The unknown-node test can also receive 401 before reaching the topology-membership check.
Create one timestamp and pass it to both the request body and signRegister().

Contain refresh-target failures per cluster.
For a preconfigured cluster without a user client, resolveClusterRefreshTarget awaits internals.getInitialClient(). That call awaits createOrchestratorValkeyClient, which resolves to GlideClient.createClient. A client-creation rejection can escape the per-cluster callback. Promise.all then rejects, so the broadcast loop is skipped for every cluster in that refresh pass. Catch and log target-resolution failures inside the callback. The existing registry remains unchanged when refresh fails.

Valkey GLIDE Node.js 2.4.0 requestTimeout customCommand timeout semantics official documentation
💡 Result:
<search_synthesis>
In Valkey GLIDE for Node.js (including version 2.4.0), the requestTimeout configuration and customCommand timeout behavior follow these established semantics: Request Timeout Semantics The requestTimeout parameter defines the maximum duration (in milliseconds) the client will wait for a request to complete [1][2][3]. This period encompasses the entire request lifecycle, including: - Sending the request to the server [1][4][3]. - Waiting for the server's response [1][4][3]. - Any required reconnection or retry attempts [1][4][3]. If a pending request exceeds this duration, the client returns a timeout error [1][3]. The default value is 250 milliseconds if not explicitly configured [1][3]. Custom Command Behavior The customCommand method executes a raw Valkey command [5][6]. Its timeout behavior is governed by the client-level requestTimeout configuration [1][4][3]. Specifically: - There is no separate "custom command timeout" parameter; the customCommand operation is subject to the same requestTimeout enforcement as standard API commands [1][3]. - As of Valkey GLIDE version 2.4.0, core improvements ensure that per-command response timeouts—including those for custom and blocking commands—are strictly enforced at the multiplexed connection layer, preventing commands from waiting indefinitely [7]. Important Considerations - Lazy Connections: If lazyConnect is enabled, the requestTimeout does not apply to the initial connection establishment [1][3]. Instead, the connection establishment is governed by a separate connectionTimeout setting [8][3]. The requestTimeout only begins counting after the connection is successfully established [1][3]. - Batch Operations: For batch requests, a specific timeout can be provided within BaseBatchOptions [9]. If not provided, it defaults to the client's configured requestTimeout [9]. - Reliability: You should ensure your requestTimeout is appropriately tuned to your p99 latency; a value that is too tight can lead to false-positive timeouts, while a value that is too loose delays failure detection [10].

Clear the timeout after discovery settles.
Promise.race leaves the delay active. A successful updateClusterNodeRegistry therefore emits a false timeout warning after 10 seconds. Clear the timer in a finally block.
The configured requestTimeout: 5000 already applies to customCommand, so the command-level timeout and overlapping-refresh concern do not apply to these clients.

resolveClusterRefreshTarget fell back to the initial client for any client-less cluster when preConfiguredConnection was set. In a mixed deployment, an inactive cluster could then be rediscovered through a different preconfigured cluster's client, storing that topology under the inactive cluster's id. Track the preconfigured clusterId (recorded at boot from the Web and K8s discovery paths; updateClusterNodeRegistry now returns the written id) and only use the initial client when the cluster being refreshed matches it. Other client-less clusters are left unchanged. A user-connected cluster still refreshes through its own client, so the preconfigured cluster is covered by that path when a session is open.

1. K8s sidecar registration (#510)
/orchestrator/registernow allows a nodeId that belongs to the discovered cluster topology (in K8s), creating the sidecar'smetricsServerMapentry on first register. The strict pre-existing-entry gate is preserved for spawned Web/Electron collectors.resolveCollectorKeyfalls back to a sharedORCHESTRATOR_KEYin K8s mode, since the orchestrator never spawns sidecars and so has no per-node key for them. The key is provisioned to both the orchestrator and the sidecars via a Kubernetes Secret.2. Stale cluster topology broadcast (#511)
refreshAllClusterRegistriesnow re-discovers each tracked cluster (through a live client belonging to that cluster) before broadcasting, so clients receive current topology instead of the connect-time snapshot. Clusters with no live client are left unchanged.Testing
