我正在查看同事的代码以实现一些新功能，并且遇到了以下表达式：version: '3.3'
services:
users-service:
container_name: users-service
build:
context: ./users-service
dockerfile: Dockerfile-dev
volumes:
- './users-service:/usr/src/app'
ports:
- "5001:5000"
[kuimov@ms testdriven-app [testdriven-dev]]$ docker-compose -f docker-compose-dev.yml build

Recreating users-service ... done
Attaching to users-service
users-service | python: can't open file 'manage.py': [Errno 2] No such file or directory

。
该比较是什么意思？它会返回什么？
谢谢！
