packages/apps/postgres/values.schema.json (1)
105-109: Schema definition could be more specificThe
itemsfield is currently empty, which means any array items would be validated against an empty schema. Consider enhancing this to properly validate the structure of Kubernetes topology spread constraints."topologySpreadConstraints": { "type": "array", "description": "The topologySpreadConstraints", "default": [], - "items": {} + "items": { + "type": "object", + "properties": { + "maxSkew": { + "type": "integer", + "description": "The degree to which pods may be unevenly distributed" + }, + "topologyKey": { + "type": "string", + "description": "The key of node labels" + }, + "whenUnsatisfiable": { + "type": "string", + "description": "How to deal with a pod if it doesn't satisfy the spread constraint", + "enum": ["DoNotSchedule", "ScheduleAnyway"] + } + } + }packages/apps/postgres/README.md (2)
63-63: Typo in Backup Parameter DescriptionThere is a typo in the description for
backup.enabled("Enable pereiodic backups"). Please correct "pereiodic" to "periodic" for clarity.
71-71: Reconsider Parameter Placement and DescriptionThe newly added
topologySpreadConstraintsparameter is inserted under the "Backup parameters" section. Given its purpose for dynamic deployment configuration, consider either:
- Moving it to a more appropriate section (e.g., "Deployment Parameters"), or
- Updating its description to clarify its role within backup or broader deployment settings.
This will help users better understand its function and context.

72-73: Version updates look good!The changes properly version the postgres package, fixing version 0.8.0 to a specific commit hash and correctly setting 0.9.0 to track HEAD.

80-85: Well-structured configuration with helpful examplesThe addition of the
topologySpreadConstraintsparameter with commented examples provides clear guidance for users who want to configure topology spread constraints.

Fix YAML indentation to ensure proper parsing
The static analysis tool reports a syntax error on line 10. While the templating logic is correct, there might be an indentation issue with how the topologySpreadConstraints key is placed relative to other spec fields.
spec:
instances: {{ .Values.replicas }}
enableSuperuserAccess: true
- {{ if .Values.topologySpreadConstraints }}
- topologySpreadConstraints:
- {{- toYaml .Values.topologySpreadConstraints | nindent 4 }}
- {{- end }}
+ {{- if .Values.topologySpreadConstraints }}
+ topologySpreadConstraints:
+ {{- toYaml .Values.topologySpreadConstraints | nindent 4 }}
+ {{- end }}
postgresql:
parameters:The issue is with the whitespace handling in the templating. Using {{- instead of {{ at the beginning of the if statement will properly trim whitespace and prevent YAML parsing errors.
📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.
