The Device Simulator consists of three major parts:
-
Fleet Manager: This is the entry point to start the simulators. It controls and monitors the lifecycle of all the Device Simulators.
-
Device Simulator: This is a simulator for an IoT device that is able to communicate with the fleet management platform and perform OTA updates. There could be multiple device simulators in a single simulation.
-
HTTP Server: External users and programs can get the current simulation stats by sending HTTP requests to the server.
A single Device Simulator has two important components: API and Controller.
-
API: This is a platform-specific API that enables the simulator to communicate with different platforms and performs different task execution logics. It will be loaded dynamically during runtime.
-
Controller: A controller holds all the details a device might need during the simulation. It also provides functionalities for dummy tasks or crash simulations and produces well-formatted logs and stats.
golang: 1.20.5
Build the simulator locally:
go build -o simulator .Build the docker image:
./build_image.shBy default, the HTTP server is running on http://localhost:8086
