OSAC-1604: Granular Cluster Status Reporting (PRD) - #209
openshift-merge-bot[bot] merged 3 commits into
Conversation
Draft PRD checkpoint for making Cluster/ClusterOrder status reporting as granular as ComputeInstance (VMaaS/OSAC-1027). Covers orthogonal conditions plus granular provisioning progress across API, CLI, and UI for CaaS. Work in progress - open items before finalizing: acceptance criteria, non-functional requirements, and the reconcile-loop-frequency assumption.

WalkthroughThe PRD defines granular CaaS cluster status reporting for provisioning stages, health signals, scaling, deletion, CLI/UI output, and monitoring. It also specifies scope exclusions, user stories, acceptance criteria, assumptions, dependencies, and non-functional requirements. ChangesCaaS status reporting requirements
Estimated code review effort: 1 (Trivial) | ~5 minutes Merge Risk: 🟡 Moderate · up to The PRD changes cluster status reporting but does not yet define the private status stream used for metering, how stalled provisioning is identified, or how deletion progress and failures are reported.

AI EP Review: EP-209Score: 8/10 | Verdict: PASS
Verdict: The PRD has a clear problem, strong justification, and good scoping, but fails on testability due to missing acceptance criteria and has moderate design leakage in the problem statement and in-scope items. Feedback: Add acceptance criteria — the PR description already flags this as an open item, and it's the primary gap preventing this PRD from passing. Define what specific provisioning stages users should see, what 'degraded with enough detail' means in observable terms, and what the CLI describe output should contain. Also clean up design leakage: replace references to 'orthogonal conditions', specific Kubernetes condition type counts (43/26), and 'Kubernetes events emitted at key provisioning transitions' with user-observable equivalents — e.g., 'monitoring and alerting signals at key provisioning transitions' instead of naming the Kubernetes mechanism.

Verdict: A well-structured, user-focused PRD that clearly defines the problem, scopes tightly to CaaS cluster status granularity, and provides testable acceptance criteria — one of the stronger PRDs in the set. Feedback: Minor improvement: the freshness NFR defers the specific bound entirely to the design EP — consider adding at least a rough expectation (e.g., 'within seconds, not minutes') so reviewers can validate the design's bound against PRD intent. The Cloud Provider Admin observability story could specify what form 'observability signals' take from the user's perspective (metrics? events? logs?) to make it more testable at PRD level.

Verdict: A well-crafted PRD that clearly defines a user-facing capability with strong problem framing, clean separation from implementation, tight scoping, and verifiable acceptance criteria. Feedback: This is a strong PRD. Minor improvements: consider adding a concrete example of what the 'stage unknown' state looks like to the user (error message, icon, etc.) to make that acceptance criterion even more testable. The 'at minimum' qualifier on provisioning stages is appropriate for a PRD but the design EP should lock down the exact stage list. The monitoring signals user story for Cloud Provider Admins could benefit from a corresponding acceptance criterion specifying what form those signals take (metrics endpoint, events, etc.) at a user-observable level.

Require granular status on the private Watch stream.
The scope names API, CLI, and UI, but it does not name the private fulfillment Watch stream. Metering consumes that stream. An implementation could satisfy the visible-surface requirements while Metering still receives collapsed PROGRESSING status or only desired node-set counts. That can produce inaccurate usage billing and over-billing during deletion.
Add an acceptance criterion and design contract for the private stream. Require orthogonal DEGRADED/failure conditions, deletion progress and failure, and per-node-set ready counts. Define update identity and freshness rules with the other API surfaces.
The Metering requirement comes from the PR objectives.

HyperShift HostedCluster status conditions deletion progress cleanup NodePool status ready replicas scaling fields
💡 Result:
In HyperShift, HostedCluster deletion progress and NodePool scaling are managed through specific status conditions and API fields [1][2][3]. HostedCluster Deletion Progress Recent updates have introduced a dedicated HostedClusterDeleting condition to provide visibility into the deletion lifecycle [4][5]. Previously, this information was only available via controller logs [4][5]. The HostedClusterDeleting condition is set to True during deletion and uses phase-specific reasons to track progress, including [4][5]: - WaitingForNodePoolDeletion - WaitingForCAPIClusterDeletion - WaitingForEndpointServiceDeletion - WaitingForPrivateConnectDeletion - WaitingForControlPlaneDeletion - WaitingForNamespaceDeletion - DeletionCompleted Additionally, the HostedCluster status includes a HostedClusterDestroyed condition which, when True, indicates that the destruction process has completed and the cluster is entering an optional grace period [6][1][7]. The duration of this grace period can be configured using the hypershift.openshift.io/destroy-grace-period annotation [1][8]. NodePool Scaling and Status NodePool scaling is managed through mutually exclusive fields in the NodePool specification [2][9][10]: - Replicas: For manual scaling, define the desired number of nodes using spec.replicas [2][9][3]. - AutoScaling: For dynamic scaling based on resource demand, define spec.autoScaling (with min and max nodes) and set spec.replicas to null [2][10][3]. The NodePool status provides visibility into current state through several fields [2][9]: - status.replicas: The latest observed number of nodes [2]. - status.conditions: Key conditions include Ready (indicating all replicas are ready), AutoscalingEnabled (verifying the validity of scaling configuration), and various update-related conditions like UpdatingVersion or UpdatingConfig [11][10]. The Ready condition aggregates data from the underlying CAPI MachineDeployment and nodes [11][3].

💡 Result:
In HyperShift, HostedCluster and NodePool statuses provide observability into cluster lifecycle, health, and scaling operations [1][2]. HostedCluster Status The HostedCluster status includes a conditions array to track the overall state and lifecycle progress of the control plane [1][3][4]. Key condition types include: - Available: Indicates a healthy control plane [4]. - Progressing: Signals an initial deployment or upgrade is in progress [4]. - Degraded: Indicates errors requiring user intervention [1][4]. - HostedClusterDeleting: A condition used to track the deletion progress through phases (e.g., WaitingForNodePoolDeletion, WaitingForControlPlaneDeletion, DeletionCompleted) [5]. - DataPlaneConnectionAvailable: Signals successful network connectivity between the control plane and data plane components [6]. NodePool Status The NodePool status reports the current number of nodes and the state of machine management [2]. It includes: - Replicas: The latest observed count of nodes in the pool [2]. - Conditions: Observations regarding the pool's state, such as [7][2]: - Ready: Bubbles up the status of underlying CAPI MachineDeployment/MachineSet resources [7]. - AllMachinesReady: Signals when machine infrastructure is successfully created [7]. - AllNodesHealthy: Signals when the nodes themselves are healthy [7]. - UpdatingVersion/UpdatingConfig: Indicates ongoing update operations [7]. Regarding deletion and scaling: - Scaling and Deletion: During scale-down or deletion, NodePools may undergo a drain process [8]. If nodes cannot be drained (e.g., due to protected pods that cannot be rescheduled), the process can block [8]. Users can manage these scenarios by configuring.spec.nodeDrainTimeout and.spec.nodeVolumeDetachTimeout in the NodePool specification [8]. - Deletion Tracking: The HostedClusterDeleting condition explicitly manages the teardown flow, ensuring dependencies like NodePools and CAPI clusters are removed in the correct order before finalizing the HostedCluster resource [5].

Define how the API identifies a stalled stage.
A visible current stage does not distinguish a healthy long-running operation from a cluster stuck in that stage. The freshness requirement only bounds status delivery. It does not define a maximum stage duration or a stalled signal.
Add a measurable stage age or last-transition timestamp, or define a timeout that produces Stalled or Degraded. Include this behavior in the API, CLI, and UI acceptance criteria.

Summary
PRD checkpoint for OSAC-1604 - Granular Cluster Status Reporting. Makes Cluster/ClusterOrder status reporting as granular as ComputeInstance (VMaaS), following the OSAC-1027 pattern, for CaaS clusters.
Core problem: the OSAC feedback controller collapses all CRD conditions into a single
PROGRESSINGproto condition before they reach the API, so tenants only ever see "PROGRESSING" during cluster provisioning. HyperShift already exposes rich HostedCluster/NodePool conditions to map from.Status: DRAFT / work in progress
Opened as a draft to checkpoint the work. Not ready for review yet.
Locked decisions (from clarify phase):
