I am trying to combine different docker compose files such as Milvus docker compose and Apache Airflow within my own devcontainer on my own computer. Therfore I have prepared my own docker-compose file:

name: mlops-airflow-milvus
services:
  app:
    build:
      context: .
      dockerfile: Dockerfile
    volumes:
      - ../:/workspaces:cached
      - ../.bashrc:/home/vscode/.bashrc
    command: sleep infinity
    ports:
      - "8000:5000"
#    networks:
#      - milvus
#      - airflow
    deploy:
      resources:
        reservations:
          devices:
            - driver: nvidia
              count: 1
              capabilities: [gpu]
### Error: cannot override networks
#  minio:
#    extends:
#      file: milvus-standalone-docker-compose.yml
#      service: minio
#    networks:
#      - milvus

Unfortunatly from my Python environment (specifyed as Dockerfile, service: app) I cannot access the Minio service instance from Milvus using the Minio-command line tool mc. It says connection refused. But if I connect from outside the devcontainer it works well. I would like to download files and store it on the (milvus)-Mino instance.

Therefore I tryed to override the networks, however this isn’t possible.

I am not sure, if this is best development practice. Another way would be to define another Minio-container just for the access from app.
