Usage notes

Defines a core system component that provides infrastructure services to the platform.

Note: CoreSystem configuration is deprecated. Use the newer configuration patterns for integration services, event sources, and event channels instead.

Schema properties#

Property	Type	Required	Default	Description
category	`string`	Yes	-	System category (storage, messaging, database, etc.)
type	`string`	Yes	-	Specific system type within the category
title	`string`	No	-	Human-readable title for the system
parameters	`Dictionary<string, object>`	No	`{}`	System-specific configuration parameters

YAML examples#

Storage system#

apiVersion: weik.io/v1alpha1
kind: CoreSystem
metadata:
  name: azure-blob-storage
spec:
  category: storage
  type: azure-blob
  title: Azure Blob Storage
  parameters:
    ConnectionString: "{{sys:azure-storage-connection}}"
    ContainerName: integrations
    RetryCount: 3

Database system#

apiVersion: weik.io/v1alpha1
kind: CoreSystem
metadata:
  name: postgres-main
spec:
  category: database
  type: postgresql
  title: Main PostgreSQL Database
  parameters:
    Host: db.example.com
    Port: 5432
    Database: weikio
    Username: weikio_user
    Password: "{{sys:database-password}}"
    MaxPoolSize: 20

Messaging system#

apiVersion: weik.io/v1alpha1
kind: CoreSystem
metadata:
  name: rabbitmq-broker
spec:
  category: messaging
  type: rabbitmq
  title: RabbitMQ Message Broker
  parameters:
    Host: rabbitmq.example.com
    Port: 5672
    VirtualHost: /
    Username: weikio
    Password: "{{sys:rabbitmq-password}}"
    AutomaticRecovery: true

Cache system#

apiVersion: weik.io/v1alpha1
kind: CoreSystem
metadata:
  name: redis-cache
spec:
  category: cache
  type: redis
  title: Redis Cache
  parameters:
    Endpoint: redis.example.com:6379
    Password: "{{sys:redis-password}}"
    Database: 0
    ConnectTimeout: 5000
    SyncTimeout: 1000

Usage notes#

CoreSystem configurations were used to define infrastructure components that other services depend on. This pattern is deprecated in favor of more specific configuration types.

Migration path#

Storage systems → Use storage-specific integrations and services
Database systems → Use DatabaseChangeTracking or direct database connectors
Messaging systems → Use EventSource and EventChannel configurations
Cache systems → Configure caching at the API or integration level

Categories#

Common system categories included:

storage: File storage, blob storage, S3
database: SQL and NoSQL databases
messaging: Message queues and brokers
cache: Caching systems
logging: Logging aggregators
monitoring: Monitoring and metrics systems

Parameters#

Parameters are system-specific and depend on the type. Common patterns:

Connection strings and endpoints
Authentication credentials (use Variables for secrets)
Timeouts and retry settings
Pool sizes and resource limits
Feature flags and options

Deprecation notice#

While CoreSystem configurations are still supported for backward compatibility, new implementations should use:

EventSource for event-driven systems
EventChannel for message routing
IntegrationService for custom services
DatabaseChangeTracking for database monitoring
Integration-specific parameters in flow configurations
