如何在gitlab-ci docker容器中使用docker-py获得docker客户端？

image: docker:latest

services:
  - docker:dind

stages:
  - build

build:
  stage: build
  script:
    - docker version

build:
  stage: build
  script:
    - apk add --no-cache python3-dev libffi-dev openssl-dev gcc libc-dev make
    - pip3 install docker-py
    - python3 your_script.py

import docker

def get_docker_client():
    client = docker.from_env()
    return client

docker_client = get_docker_client()
