I start Milvus using docker-compose and this file. All three of the components (minio, etcd, and milvus standalone) start just fine and are running.

I am also able to connect to the Milvus container from my desktop using “localhost” and the Milvus CLI tool for Mac. However, when I try to connect to the Milvus container from another container inside docker (using the same docker network), I get the following error.

FWIW, I can ping the Milvus container from the other container, and nslookup milvus-standalone returns the correct IP address in the docker network

Any suggestions on solving this? Thank you for any help in advance.
