Overview

This skill validates Dapr configurations for security, correctness, and best practices. It ensures all Dapr components and sidecar annotations follow standards before deployment.

Quick Start

Validate Existing Components

bash

# Validate a Dapr component file
python scripts/validate_component.py <component-file.yaml>

# Validate deployment Dapr annotations
python scripts/validate_deployment.py <deployment-file.yaml>

Generate New Components

bash

# Generate from templates
python scripts/generate_component.py --type statestore-postgres --name mystore --namespace todo-app

# Available templates in assets/:
# - statestore-postgres, statestore-redis
# - pubsub-kafka, pubsub-redis
# - configuration (mTLS)

Validation Rule Codes

Code	Category	Description
DAPR-001	Component	Missing namespace
DAPR-002	Component	Using 'default' namespace
DAPR-003	Security	Inline credentials (not using secretKeyRef)
DAPR-004	Component	Missing or empty scopes
DAPR-005	Configuration	mTLS not enabled
DAPR-006	Deployment	Missing dapr.io/app-id annotation
DAPR-007	Deployment	Missing sidecar resource limits
DAPR-008	Component	Invalid component type
DAPR-009	Deployment	app-id doesn't match component scopes
DAPR-010	Deployment	Missing dapr.io/app-port annotation

Component Structure

Every Dapr component MUST have:

yaml

apiVersion: dapr.io/v1alpha1
kind: Component
metadata:
  name: <lowercase-hyphenated>
  namespace: <explicit-namespace>    # Never "default"
spec:
  type: <component-type>
  version: v1
  metadata:
    - name: <key>
      secretKeyRef:                  # For sensitive values
        name: <secret-name>
        key: <secret-key>
scopes:                              # REQUIRED
  - <app-id-1>

Validation Rules

Secrets Management

yaml

# ✅ CORRECT
metadata:
  - name: connectionString
    secretKeyRef:
      name: postgres-secrets
      key: connection-string

# ❌ WRONG - Never inline secrets
metadata:
  - name: connectionString
    value: "postgresql://user:password@host/db"

Scopes (Required)

yaml

# ✅ CORRECT - Scoped to specific apps
scopes:
  - todo-backend
  - todo-mcp-server

# ❌ WRONG - Empty or missing scopes

mTLS Configuration

yaml

apiVersion: dapr.io/v1alpha1
kind: Configuration
metadata:
  name: dapr-config
spec:
  mtls:
    enabled: true    # MANDATORY

Deployment Annotations

Every Dapr-enabled deployment MUST have:

yaml

annotations:
  dapr.io/enabled: "true"
  dapr.io/app-id: "<unique-app-id>"
  dapr.io/app-port: "<container-port>"
  dapr.io/app-protocol: "http"
  dapr.io/sidecar-cpu-request: "100m"
  dapr.io/sidecar-memory-request: "128Mi"
  dapr.io/sidecar-cpu-limit: "300m"
  dapr.io/sidecar-memory-limit: "256Mi"

Component Examples

PostgreSQL State Store

yaml

apiVersion: dapr.io/v1alpha1
kind: Component
metadata:
  name: statestore
  namespace: todo
spec:
  type: state.postgresql
  version: v1
  metadata:
    - name: connectionString
      secretKeyRef:
        name: postgres-secrets
        key: connection-string
scopes:
  - todo-backend

Kafka Pub/Sub

yaml

apiVersion: dapr.io/v1alpha1
kind: Component
metadata:
  name: pubsub
  namespace: todo
spec:
  type: pubsub.kafka
  version: v1
  metadata:
    - name: brokers
      value: "kafka:9092"
    - name: authType
      value: "password"
    - name: saslUsername
      secretKeyRef:
        name: kafka-secrets
        key: username
    - name: saslPassword
      secretKeyRef:
        name: kafka-secrets
        key: password
scopes:
  - todo-backend

Validation Output

code

## Dapr Validation Report

### Component: statestore
✅ Structure valid
✅ Namespace explicit
✅ Secrets use secretKeyRef
✅ Scopes defined
❌ ERROR: Empty scopes

### Deployment: todo-backend
✅ Dapr enabled
✅ App-id matches scopes
⚠️ WARNING: No sidecar limits

### Status: PASSED / BLOCKED

Common Mistakes

Mistake	Fix
Inline secrets	Use `secretKeyRef`
Missing scopes	Add explicit app-ids
Wrong app-id	Match annotation to scopes
No sidecar limits	Add resource annotations
Missing namespace	Use explicit namespace
