Successful Start

How do I know if Milvus has started successfully? How long after all the containers are running can I start inputting data?

If Milvus is started using Docker Compose, run docker ps to observe how many Docker containers are running and check if Milvus services started correctly.

For Milvus Standalone, you should be able to observe at least three running Docker containers, one being the Milvus service and the other two being etcd management and storage service.
For Milvus Cluster, you should be able to observe at least twelve running Docker containers, nine for the Milvus service and three for basic services.
