I am implementing a IoT Edge App, and I want to get the moduleid in my container app by java SDK.
But I dont know how.

Is there any API or sample code?

Hello @罗宇恒罗宇恒

Have you tried like this: const ModuleIDstring= process.env.ModuleID;

Set the Environment env value in the deployment.template.json.

Please refer to this blog-Wriiten by Thomas Pentenrieder to get an idea.

Thanks for your feedback.

I tried this, but met build error:
[ERROR] COMPILATION ERROR :

I find the solution now, we can use following code to get ModuleId without set the Environment env value in the deployment.template.json.

ModuleClient client = ModuleClient.createFromEnvironment(protocol);
String moduleId = client.getConfig().getModuleId();
System.out.println("moduleId: " + moduleId);
