OCPBUGS-111927: fix(destroy): strip finalizers from all namespaced content before removing control plane namespace - #9334
Conversation
…oving control plane namespace The force destroy path (`hypershift destroy cluster --force`) only stripped finalizers from a fixed allowlist of CAPI/HyperShift types (cpResources), then cleared the namespace's spec.finalizers and deleted it. Objects of types not in the allowlist — such as Services with the load-balancer-cleanup finalizer or PVCs with pvc-protection — retained their finalizers. Once the namespace was garbage collected, these objects became permanently undeletable orphans because the API server rejects writes to nonexistent namespaces. This commit: 1. Extends the finalizer stripping phase to cover core Kubernetes types (Services, PVCs, Pods, ConfigMaps, Secrets, Endpoints, ServiceAccounts, StatefulSets, ReplicaSets) in addition to the existing CAPI types. 2. Adds an explicit content deletion phase (deleteNamespacedContent) that runs after finalizer stripping but before clearing spec.finalizers, ensuring all objects are actually removed from etcd before the namespace is garbage collected.

📝 WalkthroughWalkthroughForce cleanup now removes finalizers from common control-plane resources before namespace deletion. It explicitly deletes supported namespaced resources, ignores missing resources and unavailable CRDs, and aggregates other errors. Tests cover Services and PersistentVolumeClaims with finalizers, deletion of supported resources, and empty namespaces. Suggested reviewers: Merge Risk: 🟠 High · up to The destroy path now removes finalizers and deletes namespaced content before deleting the control-plane namespace, but it does not wait for those deletions to complete. A Service or PVC still terminating could be orphaned when namespace finalizers are cleared, so merge should be blocked until deletion completion is bounded and verified. 🚥 Pre-merge checks | ✅ 10 | ❌ 1❌ Failed checks (1 warning)

openshift hypershift cmd/cluster/core/destroy.go DeleteAllOf namespace finalizers
💡 Result:
In openshift/hypershift, cmd/cluster/core/destroy.go does use controller-runtime’s DeleteAllOf for namespace-scoped cleanup, and the destroy flow also has dedicated logic for handling/stripping finalizers (including namespace finalizers) to unblock deletion. A) cmd/cluster/core/destroy.go: where DeleteAllOf is used - The destroy command includes helper deleteCLISecrets(...) that deletes all v1.Secret objects in the hosted-cluster namespace (client.InNamespace(o.Namespace)) that match the AutoInfraLabelName=InfraID label selector, via c.DeleteAllOf(ctx, &v1.Secret{},...). [1] B) cmd/cluster/core/destroy.go: where finalizers (including “namespace finalizers”) are handled - Hypershift’s destroy “force” behavior explicitly describes stripping finalizers on a terminating namespace to unblock stuck namespace deletion. [2] - There are also tests/flows that remove namespace object finalizers and retry namespace deletion when it does not complete within a timeout. [3][4] C) Bottom line for your specific query - DeleteAllOf in cmd/cluster/core/destroy.go is used to bulk-delete secrets in the HostedCluster’s namespace during destroy. [1] - The “namespace finalizers” part is handled by separate destroy/force/cleanup logic that removes/strips finalizers on the namespace objects (to allow deletion to proceed). [2][3][4]

controller-runtime client DeleteAllOf behavior DeleteAllOf options documentation
💡 Result:
The DeleteAllOf method in the controller-runtime client is used to delete all objects of a specific type that match provided criteria [1][2][3]. Method Signature: func (c Client) DeleteAllOf(ctx context.Context, obj client.Object, opts...client.DeleteAllOfOption) error [1][2] Behavior: The method performs a delete collection operation on the Kubernetes API [4]. It identifies objects to delete based on the provided object type (passed via the obj parameter) and filter options (passed via opts) [1]. Important Note on Namespaces: While similar to list operations, DeleteAllOf requires a namespace to be specified in the options if the resource is namespaced [5]. Omitting a namespace in the options for a namespaced resource may result in an error from the API server (e.g., "(NotFound): the server could not find the requested resource"), rather than deleting across all namespaces [5]. Options: The opts parameter accepts any number of client.DeleteAllOfOption [1]. These options are effectively a combination of both ListOptions and DeleteOptions [4][1][5]. Because DeleteAllOfOption is an interface that applies configuration to a DeleteAllOfOptions struct, you can pass standard list and delete filters [4][1]: - List filters: Such as client.InNamespace, client.MatchingLabels, or client.MatchingFields [1][6]. - Delete filters: Such as client.GracePeriodSeconds, client.Preconditions, or client.PropagationPolicy [4][1]. Example Usage: // Delete all pods in the specified namespace with a label of 'app=test' pod:= &v1.Pod{} opts:= []client.DeleteAllOfOption{ client.InNamespace("my-namespace"), client.MatchingLabels{"app": "test"}, client.GracePeriodSeconds(0), } err:= client.DeleteAllOf(ctx, pod, opts...)

💡 Result:
There is no specific file named cmd/cluster/core/destroy.go in the HyperShift project codebase. The cluster destruction logic for the HyperShift CLI is typically organized under the cmd/destroy package [1], while platform-specific destruction logic often resides in separate platform-specific packages (e.g., cmd/cluster/aws, cmd/cluster/azure, cmd/cluster/gcp) [2][3]. The term contentTypes does not appear as a recognized standard component or configuration field within the cmd/cluster/core directory or in relation to cluster destruction routines in the current HyperShift repository. In the HyperShift project, configurations and type definitions are primarily located in the api/ directory (e.g., api/hypershift/v1beta1/hostedcluster_types.go) [4], and CLI command structures follow the cobra library pattern [5][1]. If you are looking for configuration-related types, they are generally defined in these API packages rather than in cmd/cluster/core.

site:github.com/openshift/hypershift "for _, obj := range contentTypes" "DeleteAllOf"
💡 Result:
The pattern for _, obj := range contentTypes DeleteAllOf is not a standard Go or Kubernetes client-go syntax but rather an implementation pattern found in specific Kubernetes controllers, notably within the HyperShift project [1][2]. In this context, DeleteAllOf is a method provided by the controller-runtime client.Client interface [1]. It is designed to delete all objects of a specific type that match a given set of options (such as labels or namespaces) in a single operation, rather than iterating through a list and deleting objects one by one [1]. When developers use a pattern like: for _, obj:= range contentTypes { //... logic... client.DeleteAllOf(ctx, &SomeType{},...) } They are typically automating the cleanup of related resources during a reconciliation loop or finalizer execution [1]. For example, in HyperShift, DeleteAllOf is used within finalizers to ensure that when a parent resource (like a NodePool) is deleted, all its associated child resources (like ConfigMaps or other components) are cleaned up from the namespace [1]. The use of DeleteAllOf is often preferred over manual iteration because: 1. Efficiency: It offloads the bulk deletion operation to the Kubernetes API server [1]. 2. Atomicity/Reliability: It simplifies the logic required to ensure all associated resources are removed before a parent resource's finalizer is cleared [1]. If you are encountering this in a codebase, it is likely a server-side cleanup operation where the controller is performing a batch deletion of sub-resources associated with a primary resource being reconciled [1][2].

Kubernetes namespace deletion remove finalizers orphan resources namespace finalizer official documentation
💡 Result:
A Kubernetes namespace stuck in the Terminating state typically occurs because of lingering resources within the namespace that have finalizers, or because the namespace's own finalizer (kubernetes) cannot be cleared by the namespace controller [1][2][3]. Finalizers are a mechanism designed to ensure that dependent resources or external cleanup tasks are completed before an object is removed from the system [4]. When you delete a namespace, the control plane attempts to delete all resources within it [1][4]. If a resource has a finalizer that a controller cannot resolve (e.g., an unavailable API service or a stalled operator), the resource remains, and the namespace cannot complete its termination [1][2][5]. Orphaned resources can occur if finalizers are forcefully removed before their associated cleanup tasks are finished, or due to edge cases where the namespace controller fails to detect or delete resources [6][7]. The official Kubernetes documentation advises against manually removing finalizers [4]. Finalizers are present for critical reasons, and force-removal can lead to orphaned resources in the cluster or inconsistencies with external systems [4]. If a namespace is stuck, follow these steps in order: 1. Investigate the cause: Check for resources still present in the namespace using kubectl api-resources or similar tools [8]. Use the following command to check why the namespace is stuck: kubectl get ns -o json | jq '.status.conditions' [8] 2. Remove remaining resources: If specific resources are identified, attempt to delete them normally [1][8]. If they are also stuck, you may need to patch those specific resources to remove their finalizers [2][3]: kubectl patch -n -p '{"metadata":{"finalizers":null}}' --type=merge [3] 3. Force clear the namespace finalizer (Last Resort): If all resources are verified to be gone but the namespace remains Terminating, the kubernetes finalizer on the namespace itself may be the blocker [2][8]. You can bypass the controller by editing the namespace via the /finalize API endpoint [1][5]. - Export the namespace YAML: kubectl get ns -o yaml > ns.yaml [1][8] - Remove the kubernetes entry from the spec.finalizers list [1][8]. - Use the API to finalize the deletion [1][3]: curl -k -H "Content-Type: application/yaml" -X PUT --data-binary @ns.yaml https:///api/v1/namespaces//finalize [1][5] Forcefully deleting a namespace via --force or removing finalizers is considered a last-resort action [2][8][4]. Always ensure that any external resources managed by the finalizer have been cleaned up manually if the controller could not do so [2][4].

Kubernetes namespace controller DeleteAllContent finalizer namespace deletion source
💡 Result:
In Kubernetes, the namespace controller manages the deletion of a namespace through a specialized cleanup process [1][2][3]. When a namespace is deleted, it is not removed from the API server immediately; instead, it is marked with a deletionTimestamp and enters the Terminating phase [1][4]. The namespace controller is responsible for the actual removal of resources within the namespace [1][3]. While there is no single finalizer literally named "DeleteAllContent," the controller's functionality—implemented in the namespaced resources deleter—is specifically designed to iteratively discover and delete all content within the namespace [5][2][6]. The deletion process follows this workflow: 1. Deletion Initiation: When a user deletes a namespace, the API server sets the deletionTimestamp [3][4]. 2. Resource Discovery and Cleanup: The namespace controller watches for terminating namespaces and triggers its cleanup logic [1][4]. It uses discovery to identify all API resources present in the cluster and systematically deletes those associated with the namespace [5][6]. 3. Finalizer Logic: The "kubernetes" entry in the namespace's metadata.finalizers list acts as the core blocker [3][4]. The namespace controller is responsible for removing this finalizer, but it will only do so once all content has been confirmed as deleted [3][4]. 4. Namespace Removal: Once all contents are cleared and all finalizers—including the default "kubernetes" finalizer—are removed, the namespace is permanently deleted from storage [3][4]. If a namespace remains stuck in the Terminating phase, it is typically because the namespace controller cannot complete this cleanup [4][7]. Common causes include: - Unavailable APIServices: If an aggregated APIService is unhealthy, discovery fails, and the controller halts [4][7][8]. - Stuck Resources: Resources within the namespace may have their own finalizers that never clear, often because the operator responsible for them is missing or failed [4][7]. - Controller Errors: The namespace controller might be unable to communicate with the API server or process the deletion of specific resource types [9][10]. To diagnose this, you can check the namespace's status conditions (e.g., NamespaceFinalizersRemaining or NamespaceDeletionContentFailure) or inspect the namespace manifest to see which finalizers or resources are blocking the process [4][7]. Removing the finalizers manually should only be used as a last resort, as it can result in orphaned resources remaining in the cluster [9][7][10].

site:github.com/openshift/hypershift/pull/8890 destroy.go namespace finalizers DeleteAllOf
💡 Result:
In Kubernetes controller development using controller-runtime, DeleteAllOf is a client method used to delete all objects of a specific type that match given options (such as labels or namespaces) [1]. It is frequently employed within finalizer logic during the deletion of a parent resource [2]. When a parent object is deleted and marked for removal, the finalizer ensures that all dependent or child resources are cleaned up before the parent itself is removed from the system [2]. Using DeleteAllOf within this finalizer logic allows the controller to trigger a bulk deletion of these related objects, often targeting a specific namespace to ensure orphans are not left behind [2]. Key technical points regarding this pattern include: 1. Direct API Interaction: Unlike Get or List operations, which typically read from the controller-runtime cache, DeleteAllOf operations are performed directly against the Kubernetes API server [1]. 2. Dependency Management: It is a common design pattern to verify that the DeleteAllOf operation has successfully completed (i.e., that dependent objects are gone) before removing the finalizer from the parent object [2]. This ensures that the parent resource is not deleted while child resources still exist, which could lead to orphaned objects or unexpected state issues [2]. 3. Context: While there is no standard file named destroy.go in the core Kubernetes codebase that mandates this behavior, it is a frequent naming convention for files containing cleanup or deletion logic in custom operators and controllers [2].

💡 Result:
There is no standard Go library or universally defined file named destroy.go. Instead, destroy.go is a common naming convention used by Go developers for files that contain logic related to cleaning up, deleting, or destroying resources [1][2][3][4][5]. Because Go does not have a built-in "destructor" concept (unlike languages like C++), developers often create explicit methods or files—frequently named destroy.go—to handle the teardown of objects, infrastructure components, or persistent storage [1][2][4][5]. Common use cases for a file named destroy.go include: 1. Infrastructure Management: Tools like OpenShift installer or other cloud infrastructure providers use destroy.go files to house command-line logic or internal functions that delete clusters, virtual machines, or other cloud resources [1][3]. 2. Resource Cleanup: In libraries wrapping C-based APIs (such as ImageMagick), a destroy.go file may provide wrappers to manually free C-allocated memory that the Go garbage collector cannot manage [5]. 3. Database/State Storage: Projects like CockroachDB use such files to handle the removal of data replicas or associated storage state [4]. 4. Automation Engines: Infrastructure-as-code tools (e.g., Pulumi) use files named destroy.go to define the logic for destroying existing stacks or deployment environments [2]. In summary, if you encounter a file named destroy.go in a project, it is a custom implementation specific to that codebase, typically responsible for resource deallocation, uninstallation, or cleanup tasks [1][2][3][4][5].

site:github.com/openshift/hypershift "Phase 3" "Spec.Finalizers" destroy
💡 Result:
The query "Phase 3 Spec.Finalizers destroy" appears to conflate two distinct development contexts within the HyperShift (OpenShift Hosted Control Planes) project. 1. Phase 3 Managed Identity Work: The term "Phase 3" refers to a specific feature development track within HyperShift, specifically related to Azure Managed Identity [1]. This work involved updating the Azure API to support CredentialsSecretName and deprecating older fields like ClientID and CertificateName [1]. It is unrelated to the technical mechanism of Kubernetes finalizers or their destruction. 2. Spec.Finalizers and Destroy Logic: The phrase "Spec.Finalizers destroy" relates to the management of finalizers during cluster deletion in HyperShift. In Kubernetes/HyperShift, resources often have finalizers (often found in metadata.finalizers rather than spec.finalizers) that prevent them from being deleted until specific cleanup tasks (such as removing infrastructure) are complete [2]. Key aspects of HyperShift finalizer management during destroy operations include: * Force Destruction: A --force flag was introduced in hypershift destroy cluster to allow for the manual stripping of finalizers when standard deletion grace periods expire [3]. This is intended to resolve issues where clusters become stuck in a terminating state due to cloud API failures or hung cleanup controllers [3]. * Finalizer Cleanup Logic: The system uses functions (e.g., waitForRestOfFinalizers) to coordinate the orderly removal of finalizers [4][5]. Recent improvements have focused on ensuring that if these wait periods time out, the process logs a warning rather than aborting, allowing underlying infrastructure cleanup to proceed [4][5]. * Control Plane Protection: Finalizers are also used at the framework level to ensure that control plane workloads (like CAPI providers) are not prematurely deleted, which could otherwise lead to orphaned infrastructure [2]. If you are encountering an issue where a resource is stuck in a Terminating state, it is likely due to a blocked finalizer process rather than a specific "Phase 3" requirement [3][6]. Official HyperShift documentation recommends ensuring that the relevant controllers (e.g., Karpenter, Azure machine controllers) are healthy, or using the --force flag in the destroy CLI if necessary [3][7].

site:github.com/openshift/hypershift "DeleteAllOf(ctx, obj"
💡 Result:
The term DeleteAllOf(ctx, obj) is not a standard function in the Go language or the official Kubernetes client-go library. Instead, it is a custom helper utility function found within the HyperShift project (an open-source project for running managed OpenShift clusters) [1][2]. In the context of the HyperShift codebase, this function is typically part of a utility package (such as support/k8sutil or earlier in support/util) used to manage the lifecycle of Kubernetes resources [1]. It is commonly used by controllers—such as the NodePool controller—to perform bulk deletion of resources, such as ConfigMaps, associated with a parent object before that parent object is itself deleted [2]. Because it is a project-specific utility rather than a general-purpose library function, its exact signature and behavior are defined by the implementation within that specific codebase. If you are encountering this in your code, it is likely referencing a custom utility function specific to your project's repository [1][2].

Wait for resource deletion before namespace finalization.
DeleteAllOf submits deletion requests but does not wait for resources to leave the API. If Phase 3 clears ns.Spec.Finalizers while a resource is terminating, namespace deletion can orphan that resource. Poll the supported resource lists with a bounded context and return the aggregated error if content remains or deletion fails. Add a delayed-deletion test.

In `@cmd/cluster/core/destroy.go` around lines 445 - 451, Update the Phase 3
deletion flow around c.DeleteAllOf to wait for supported resource lists to
become empty using a bounded context before clearing namespace finalizers.
Preserve ignored NotFound and NoMatch errors, but aggregate and return any
deletion or polling failures, including resources that remain. Add a test
covering delayed resource deletion before namespace finalization.

What this PR does / why we need it:
During
hypershift destroy, the control plane namespace can be removed while objects with finalizers (e.g. Services withservice.kubernetes.io/load-balancer-cleanup, PVCs withkubernetes.io/pvc-protection) still exist inside it. These orphaned objects become permanently undeletable because their namespace is gone but their finalizers were never cleared.This fix restructures
forceRemoveAllFinalizersinto three phases:DeleteAllOffor each resource type, ensuring nothing survives past the namespace removal.This ordering guarantees that the namespace is empty before its finalizers are cleared, preventing the race condition that leads to orphaned resources.
Which issue(s) this PR fixes:
Fixes https://redhat.atlassian.net/browse/OCPBUGS-111927
Special notes for your reviewer:
deleteNamespacedContentfunction usesDeleteAllOfwhich silently skips types that don't exist (viaIsNotFound/IsNoMatchErrorchecks).contentTypeslist indeleteNamespacedContentandcoreResourceslist inforceRemoveAllFinalizersare kept in sync by convention (noted in comments).deleteNamespacedContenthandles empty namespaces and API errors correctly.Checklist:
