 To ensure the Serverless Container is completely ready, both in terms of the HTTP port and the software scope, it is recommended to use **custom health checks**.

In this case, we recommend you implement a custom HTTP route on the Container that returns its readiness status.

-  A simple health check to implement is just a simple `GET` on `/` to make sure the HTTP server is properly listening.

+
+Update your Serverless Container to use custom health checks by following the instructions in the [Serverless Containers documentation](/serverless-containers/how-to/manage-a-container/#how-to-manage-a-container-deployment).
