feat(hack): add manifests to facilate manual testing - #3452
Conversation
📝 WalkthroughWalkthroughThe change adds OpenShift observability operators, Garage storage, synthetic log generation, HTTP and syslog receivers, load-balancer routing, ClusterLogForwarder overlays, and a logging UIPlugin. It also updates namespaces, Loki storage references, and operator channels. ChangesLogging test infrastructure
Estimated code review effort: 5 (Critical) | ~90 minutes Merge Risk: 🟠 High · up to Several manifests can be rejected or fail to provide their intended logging and monitoring paths, while receiver reliability and storage-security issues remain.

Inline comments:
In `@hack/manifests/log-generator/base/log_generator_deployment.yaml`:
- Around line 5-7: Add spec.selector.matchLabels to the Deployment spec, using
labels identical to those under the pod template so the rendered apps/v1
Deployment has a valid matching selector.
In `@hack/manifests/log-generator/base/service.yaml`:
- Around line 5-10: Add spec.selector to the Service manifest and set
app.kubernetes.io/name to log-generator so it matches the rendered pod labels
and creates EndpointSlices.
In `@hack/manifests/log-generator/base/servicemonitor.yaml`:
- Around line 6-9: Update the ServiceMonitor spec.selector in the log-generator
manifest to nest the existing app.kubernetes.io labels under matchLabels,
preserving their values and leaving the selector semantics unchanged.
In `@hack/manifests/observability-operators/garage/config/garage.toml`:
- Line 13: Configure TLS for the Garage S3 listener associated with
api_bind_addr, then update the corresponding storage-secret endpoint from
http:// to https:// while preserving the existing service host and port.
- Line 9: The Garage rpc_secret must not remain in the committed ConfigMap
configuration. In
hack/manifests/observability-operators/garage/config/garage.toml lines 9-9,
remove the literal secret and configure Garage to obtain it from a Kubernetes
Secret; in hack/manifests/observability-operators/garage/kustomization.yaml
lines 14-17, stop packaging that value through garage-config and add or
reference the Kubernetes Secret containing the RPC secret, preserving the
existing Garage configuration behavior.
In `@hack/manifests/observability-operators/garage/README.md`:
- Line 12: Update the README deployment command near “oc apply -k” to reference
the repository’s actual Garage manifest path from the repository root, or
explicitly document the working directory required for the existing relative
path.
In `@hack/manifests/observability-operators/garage/storage-secret.yaml`:
- Line 6: Update the Garage endpoint configuration in the storage Secret to use
HTTPS, or explicitly gate this manifest to isolated test clusters and document
that restriction alongside the deployment configuration; preserve the existing
endpoint and credential wiring otherwise.
In `@hack/manifests/receivers/dynamic/main.go`:
- Line 94: Limit the body read in the receiver handler around io.ReadAll by
enforcing a defined maximum byte size, detect when the limit is exceeded, and
respond with HTTP 413 before processing the batch. Keep normal reads within the
limit unchanged and retain existing error handling for other read failures.
- Line 228: Update the startup flow around Start so server and lastState are
assigned only after Start succeeds; leave lastState unchanged when startup
fails, allowing later polls to retry and preventing Stop from closing an
uninitialized stopChan.
- Line 166: Update the shutdown logic around tcpConn and activeClients to
explicitly close each active connection before clearing the active-client
collection, rather than only calling SetLinger(0). Ensure idle keep-alive
handlers unblock promptly so s.wg.Wait() is not delayed.
In `@hack/manifests/receivers/http/http_receiver_configmap.yaml`:
- Line 15: Update the newline-delimited framing configuration in the HTTP
receiver to set framing.newline_delimited.max_length to an appropriate bounded
value and configure oversized_action, such as drop, so oversized newline-free
frames are discarded instead of buffered indefinitely.
In `@hack/manifests/uiplugin/kustomization.yaml`:
- Line 3: Remove the namespace setting from the Kustomization so generated
UIPlugin resources do not receive metadata.namespace; leave the remaining
Kustomize configuration unchanged.
In `@hack/manifests/uiplugin/ui_plugin_logging.yaml`:
- Line 12: Align the UI plugin output configuration with the ClusterLogForwarder
data model by explicitly setting dataModel to Otel when retaining schema: otel,
or change the schema value to viaq so both configuration paths use ViaQ
consistently.

Vector http_server source newline_delimited framing max_length default oversized_action documentation
💡 Result:
In the Vector http_server source, when using the newline_delimited framing method, you can configure the max_length and oversized_action options within the framing.newline_delimited section of your configuration [1][2]. max_length This option specifies the maximum length of the byte buffer in bytes, excluding the trailing delimiter [2]. By default, no maximum length is enforced [2]. If you are concerned about processing malformed data or handling user-controlled input, it is recommended to set this to a reasonably large value to prevent unbounded memory usage [2]. oversized_action This option defines the action taken when a line exceeds the max_length limit [1]. Available actions include: drop: The entire oversized line is discarded [1]. truncate: The line is truncated to the max_length, and the remaining bytes up to the next delimiter are discarded [1]. Example Configuration: sources: my_source_id: type: http_server address: 0.0.0.0:80 framing: method: newline_delimited newline_delimited: max_length: 1024 oversized_action: drop decoding: codec: bytes

Exploitability: Trivial
Set a maximum newline-delimited frame length.
A client that can reach this receiver can send a newline-free request body. Vector does not enforce a default maximum for newline-delimited frames, so the receiver can buffer unbounded input and exhaust memory. Set framing.newline_delimited.max_length and an appropriate oversized_action, such as drop.

openshift observability.openshift.io UIPlugin CRD v1alpha1 spec.scope
💡 Result:
Based on the official documentation for the Cluster Observability Operator (COO) and the UIPlugin custom resource definition (CRD), there is no spec.scope field documented or utilized in the observability.openshift.io/v1alpha1 UIPlugin specification [1][2][3][4][5]. The UIPlugin CRD is primarily configured using the spec.type field to designate which plugin to enable (e.g., Logging, Monitoring, DistributedTracing, or TroubleshootingPanel), followed by specific configuration blocks under spec corresponding to that type (such as spec.logging or spec.monitoring) [1][2][4][5][6]. The operator manages these plugins globally for the cluster console rather than via a scope-based definition in the CRD [3].

💡 Result:
The term uiplugins.observability.openshift.io is part of the API group path associated with the Observability Operator, which is used to manage and extend observability functionality in the OpenShift web console [1]. Specifically, it refers to the API group for the UIPlugin Custom Resource Definition (CRD), which uses the API version observability.openshift.io/v1alpha1 [1][2]. This operator allows administrators to enable various observability-focused UI plugins for the OpenShift console by creating UIPlugin custom resources [1]. Supported plugins typically include: - Dashboards: Adds UI panels for troubleshooting and signal exploration [1]. - TroubleshootingPanel: Deploys a troubleshooting panel that interfaces with the Korrel8r engine [1]. - Monitoring: Enables features like Perses dashboards and integration with managed observability components (e.g., alertmanager, thanos querier) [1][2]. - Distributed Tracing: Enables the distributed tracing console plugin [1]. The Observability Operator (often associated with the rhobs organization in GitHub repositories) manages the lifecycle of these plugins [1][2]. When a UIPlugin CR is created, the operator deploys the corresponding services and configurations required for that specific plugin to function within the OpenShift console environment [1][2].

Remove namespace: from this Kustomization. UIPlugin is cluster-scoped, but Kustomize v5.4.3 does not recognize this custom GVK as cluster-scoped without its CRD schema. It therefore renders metadata.namespace, which the Kubernetes API rejects for a cluster-scoped resource.

OpenShift Logging UIPlugin logging schema otel ViaQ dataModel ClusterLogForwarder LokiStack
💡 Result:
In OpenShift Logging, the integration between the Logging UI plugin, the ClusterLogForwarder, and LokiStack revolves around the selection of a log data model, specifically transitioning from the legacy ViaQ format to the modern OpenTelemetry (Otel) standard [1][2][3]. Logging UI Plugin Schema The UIPlugin custom resource (CR) includes a schema parameter under spec.logging that determines how the logging console queries and interprets log data [4][5]. The allowed options are: - otel: Configures the UI to use the OpenTelemetry schema [4][6]. - viaq: Configures the UI to use the legacy ViaQ schema (default) [4][6]. - select: Displays a dropdown in the UI allowing users to toggle between these schemas for their queries [4][6]. Note that this schema feature requires OpenShift Container Platform 4.15 or later [4]. ClusterLogForwarder and Data Models The ClusterLogForwarder (CLF) CR manages how logs are collected and forwarded to a LokiStack [7][8]. When configuring an output of type lokiStack, you can explicitly define the data model using the dataModel field [1][9]: - ViaQ: The default model, which is a legacy format [1]. - Otel: The modern OpenTelemetry-based model [1][9]. While the CLF currently defaults to ViaQ when the field is unset, this default is slated to change to Otel in future releases [1]. Specifying dataModel: Otel ensures explicit use of the OTLP-based format [1][9]. When using the Otel data model, the lokiStack.labelKeys configuration is not supported [1][9]. LokiStack Integration When forwarding to a LokiStack using the Otel data model, the Loki Operator (running in openshift-logging mode) automatically maps OTLP attributes to Loki stream labels and structured metadata [10]. This allows logs, which are transported via the OTLP specification, to be queried and stored effectively within Loki [2][10]. Some attributes exist as compatibility layers to maintain support for legacy UI features while the system fully transitions to OpenTelemetry [2][3].

site:docs.redhat.com logging UIPlugin spec.logging.schema select otel viaq data model must match
💡 Result:
In the context of the Red Hat OpenShift Logging stack and the Cluster Observability Operator (COO), the spec.logging.schema field in the UIPlugin custom resource (CR) defines how the logging user interface parses and displays log data [1][2]. When configuring this field, you have three options: otel, viaq, or select [1][2]. 1. Selection: - otel: Configures the UI to use the OpenTelemetry data model [2]. - viaq: The default setting, which uses the legacy ViaQ data model [1][2]. - select: Allows users to switch between the models within the web console during log queries [1][2]. 2. Data Model Matching: It is critical that the schema defined in your UIPlugin CR matches the dataModel configured in your ClusterLogForwarder (CLF) CR [3][4]. When you configure your ClusterLogForwarder to forward logs to a LokiStack, you must specify the dataModel (either ViaQ or Otel) [3][5]. The UIPlugin schema must align with this choice to ensure the logs are parsed, queried, and displayed correctly [1][6]. 3. Key Requirements and Considerations: - Versions: The schema feature is supported in OpenShift Container Platform 4.15 and later [1][7]. - Compatibility: The OpenTelemetry data model is intended to replace the legacy ViaQ model [3][4]. While some attributes in the OpenTelemetry data model provide minimal backward compatibility (e.g., compatibility attributes) to support older UI functionality, these are deprecated and intended to be replaced as the UI fully adopts the OpenTelemetry standard [8]. - Known Issues: In some older versions (e.g., 5.8–6.2), non-administrator users have faced limitations when querying logs using the otel schema [1][7][2]. Additionally, always ensure that your spec.logging.lokiStack.name in the UIPlugin matches the name of your deployed LokiStack instance [2].

Align the UI schema with the ClusterLogForwarder data model.
schema: otel makes the UI query the OpenTelemetry model, but the LokiStack output omits dataModel. The ClusterLogForwarder contract defaults an omitted value to Viaq, so the UI can query OTEL fields while the collector forwards ViaQ records. Set dataModel: Otel for the output, or change this value to schema: viaq.
