device-addon

Move to https://github.com/open-cluster-management-io/addon-contrib/tree/main/device-addon

The device-addon integrates devices connected to IoT application layer.

Features

• Unified Kubernetes style device management APIs.
  • Driver defines a type of devices using same kind of protocol, which includes protocol properties, like the MQTT, OPC UA, etc.
  • Device gives the definition of a specific device, like what data attributes does the device have, what commands can the device support.
• Centralized management of the device on a central hub, user manage their device on the hub with device management APIs, on the edge cluster, the device-addon gets the device meta information from the hub with device management APIs and manages the device with the device meta information.
• Easily publish device data to IoT application layer via MQTT protocol, by default, device-addon start a build-in MQTT broker, IoT application/services can subscribe the device data from the broker, user also can use DeviceAddOnConfig API to configure an external broker for the device-addon.
• Multiple protocol support
  • The device-addon is able to collect data from IoT devices that are connected to external MQTT brokers.
  • The device-addon is able to collect data from IoT devices that are connected to OPC-UA servers.
  • TBD Modbus, CAN, BACnet etc.

Architecture

TODO list

• Support read commands to read the data from devices actively.
• Support write commands to write the data to devices.
• Support to persist the device data on the edge cluster.
• Support to query the history data on the edge cluster.
• Support more IoT protocols, such as Modbus, CAN, BACnet etc.
