packages/system/grafana-operator/charts/grafana-operator/crds/grafana.integreatly.org_grafanacontactpoints.yaml (2)
42-136: LGTM with a minor suggestion: Comprehensive spec definition for GrafanaContactPoint.The spec definition is well-structured and covers all necessary aspects of a contact point configuration. The immutable instanceSelector, default resyncPeriod with validation, and comprehensive type enum are particularly noteworthy.
Consider adding a brief description for the
settingsfield (line 105) to clarify its purpose and expected content, as it usesx-kubernetes-preserve-unknown-fields: true.
215-219: LGTM with a future consideration: Proper versioning and subresource definition.The CRD is correctly marked as served and stored for v1beta1, and includes a status subresource for proper status updates.
For future versions, consider implementing a conversion strategy if you plan to introduce new versions of this CRD. This will ensure smooth upgrades and backward compatibility as the API evolves.
packages/system/grafana-operator/charts/grafana-operator/crds/grafana.integreatly.org_grafanadatasources.yaml (1)
53-53: LGTM: Improved field descriptions and deprecation notices.The added descriptions for 'spec', 'allowCrossNamespaceImport', and other fields enhance the CRD's documentation. Marking 'editable' and 'orgId' as deprecated is helpful for users.

Also applies to: 56-57, 70-70, 80-82
packages/system/grafana-operator/charts/grafana-operator/crds/grafana.integreatly.org_grafanafolders.yaml (3)
104-120: LGTM. Consider updating documentation.The changes to the 'spec' section are well-thought-out and improve the functionality and clarity of the CRD:
- The new 'parentFolderRef' and 'parentFolderUID' fields provide more flexibility in folder organization.
- The updated description for the 'permissions' field clarifies its purpose.
- The 'resyncPeriod' field now has a default value and a more detailed description, which is helpful for users.
Consider updating any related documentation or user guides to reflect these changes, especially the new fields and the default resync period.
127-131: LGTM. Consider clarifying the error message.The addition of the validation rule to ensure that only one of 'parentFolderUID' or 'parentFolderRef' is set is a crucial safeguard against conflicting configurations.
Consider updating the error message to be more specific:
message: "Only one of parentFolderUID or parentFolderRef can be set. Please specify either parentFolderUID or parentFolderRef, but not both."This provides clearer guidance to users on how to correct the configuration if the validation fails.
139-216: LGTM. Consider clarifying the 'hash' field description.The additions to the 'status' section are well-structured and follow Kubernetes best practices:
- The 'conditions' field provides a standardized way to report the status of the resource.
- The 'hash' and 'lastResync' fields offer useful metadata for tracking the state and last update of the resource.
The description for the 'hash' field (lines 209-211) appears to be a placeholder. Consider updating it to clearly describe the purpose and content of the hash. For example:
description: "A hash representing the current state of the GrafanaFolder resource. This can be used to quickly determine if the resource has changed."packages/system/grafana-operator/charts/grafana-operator/crds/grafana.integreatly.org_grafananotificationpolicies.yaml (3)
18-23: LGTM: Schema definition is well-structured. Consider adding a short description.The schema definition for the CRD is correctly structured:
- Uses v1beta1 as the initial version, which is a good practice for allowing future changes
- Utilizes openAPIV3Schema for proper validation
Consider adding a short description for the v1beta1 version to provide context about its features or intended use. For example:
- name: v1beta1 description: Initial beta version of the GrafanaNotificationPolicy API schema: openAPIV3Schema: description: GrafanaNotificationPolicy is the Schema for the GrafanaNotificationPolicy API
42-176: LGTM: Comprehensive spec section. Consider enhancing data validation.The spec section of the CRD is well-structured and covers essential aspects of notification policy configuration:
- Flexible instanceSelector for targeting Grafana instances
- Detailed route property for configuring notification routing
- Comprehensive options for matching and grouping alerts
Consider enhancing data validation for some fields:
- Add format validation for duration fields:
group_interval: description: group interval type: string format: duration pattern: ^([0-9]+(\.[0-9]+)?(ns|us|µs|ms|s|m|h))+$ group_wait: description: group wait type: string format: duration pattern: ^([0-9]+(\.[0-9]+)?(ns|us|µs|ms|s|m|h))+$
- Add enum validation for the
continuefield:continue: description: continue type: boolean enum: [true, false]These changes will improve the robustness of the CRD and prevent potential configuration errors.
254-257: LGTM: Proper versioning and subresource definition. Consider adding print columns.The CRD versioning and subresources are correctly defined:
- v1beta1 is appropriately marked as served and stored
- Status subresource is correctly included
Consider adding additional printer columns to improve the output of
kubectl getcommands. For example:additionalPrinterColumns: - name: Status type: string jsonPath: .status.conditions[?(@.type=="Ready")].status - name: Age type: date jsonPath: .metadata.creationTimestampThis addition will make it easier for users to quickly view the status and age of GrafanaNotificationPolicy resources.
packages/system/grafana-operator/charts/grafana-operator/crds/grafana.integreatly.org_grafanaalertrulegroups.yaml (3)
44-226: LGTM: Spec section is well-defined with appropriate validations.The spec section for GrafanaAlertRuleGroup is comprehensive and includes necessary fields for configuring alert rule groups. The use of duration formats, immutability constraints, and validation rules (e.g., for folderRef and folderUID) demonstrates attention to detail and adherence to best practices.
Consider adding a minimum length validation for the
rulesarray to ensure that at least one rule is defined in each GrafanaAlertRuleGroup. This can be achieved by adding aminItemsproperty to therulesarray definition. For example:rules: type: array minItems: 1 items: # ... existing items definition ...This would prevent the creation of empty alert rule groups, which might not be a desired state.
113-221: LGTM: AlertRule structure is well-defined with appropriate validations.The AlertRule structure within the rules array is comprehensive and includes necessary fields for defining Grafana alert rules. The use of specific validations, such as title length limits and UID patterns, demonstrates attention to detail.
Consider the following improvements to enhance the robustness of the AlertRule definition:
- Add a description for the
isPausedfield to clarify its purpose.- Consider adding a
maxItemslimit to thedataarray to prevent an excessive number of queries in a single rule.- Add a pattern validation for the
forduration field, similar to the one used forintervalandresyncPeriod.Example for the
forfield validation:for: type: string format: duration pattern: ^([0-9]+(\.[0-9]+)?(ns|us|µs|ms|s|m|h))+$These additions would further improve the clarity and integrity of the AlertRule definitions.
231-311: LGTM: Status section follows Kubernetes conventions for resource status reporting.The status section of the GrafanaAlertRuleGroup CRD is well-structured and adheres to Kubernetes best practices for representing resource status. The use of conditions allows for detailed and standardized reporting of the resource's state.
Consider enhancing the status section with additional fields specific to GrafanaAlertRuleGroup. For example, you could add fields to report:
- The number of successfully applied rules.
- The last successful sync time.
- Any errors encountered during rule application.
Example addition to the status section:
status: description: GrafanaAlertRuleGroupStatus defines the observed state of GrafanaAlertRuleGroup type: object properties: conditions: # ... existing conditions definition ... appliedRulesCount: type: integer description: The number of rules successfully applied to the Grafana instance lastSyncTime: type: string format: date-time description: The last time the rules were successfully synced with the Grafana instance lastSyncError: type: string description: The last error encountered during rule synchronization, if any required: - conditionsThese additional fields would provide more detailed insights into the current state of the GrafanaAlertRuleGroup resource.

1-18: LGTM: YAML structure is correct and follows best practices.The YAML structure for this ClusterRole definition is well-formatted and adheres to Kubernetes resource definition standards.
3-5: Consider the security implications of a cluster-scoped role.The
ClusterRolegrants permissions cluster-wide, which could potentially be a security concern if the associated service account is compromised.Please consider the following:
- Is it possible to limit the scope of these permissions to specific namespaces where the Grafana operator will be deployed?
- If cluster-wide permissions are absolutely necessary, ensure that proper security measures are in place to protect the associated service account.
To help verify the necessity of cluster-wide permissions, you can run the following script:
This script will help identify any existing justifications for cluster-wide permissions and potential usage of namespace-specific operations related to routes.
6-18: Verify the necessity of granted permissions and document their purpose.The ClusterRole grants broad permissions (create, delete, get, list, update, watch) for OpenShift routes. While these may be necessary for the Grafana operator to function in an OpenShift environment, it's important to ensure that:
- All these permissions are indeed required for the operator's functionality.
- The scope of these permissions is not overly broad.
Please confirm that all these permissions are necessary. Additionally, consider adding comments or documentation explaining why these specific permissions are required for the Grafana operator in an OpenShift environment.
To help verify the usage of these permissions, you can run the following script:
This script will help identify where and how these OpenShift route permissions are being used in the codebase.
