Component YAML Structure

Basic Structure

apiVersion: dapr.io/v1alpha1
kind: Component
metadata:
  name: component-name        # Referenced in application code
  namespace: default          # Optional, defaults to 'default'
spec:
  type: state.redis           # Component type
  version: v1                 # Component version
  metadata:                   # Component-specific configuration
  - name: redisHost
    value: localhost:6379
  # Secret reference example:
  - name: redisPassword
    secretKeyRef:
      name: redis-secret
      key: password
scopes:                       # Optional: limit access to specific apps
  - app1
  - app2
