我对 Docker 比较陌生，我正在尝试使用 docker-compose 从我的 Dockerfile 构建单个自定义映像。

Dockerfile

FROM continuumio/anaconda3

#create a directory 
WORKDIR /home/docker/qts

#copy the dependencies file
COPY ./requirements.txt .

#install necessary packages
RUN pip install --no-cache-dir -r requirements.txt

#Expose ports
EXPOSE 5000

码头工人-compose.yml

version: "3.8"
services:
  pyimg:
    build: .
    ports: 
      - 5000:5000
    volumes:
      - $HOME/Documents/qts:/home/docker/qts

我的问题

运行docker-compose build没有给我任何错误。当我执行docker run -it <image_name> bash并导航到目录 /home/docker/qts 时，该目录不会镜像本地目录。

Adocker inspect还显示未安装卷（并且我暴露的端口也没有映射到本地端口！）我在这里缺少什么？

谢谢您的意见。

你看不到 docker run 你可以像下面这样检查；

version: "3.8"
services:
  pyimg:
    build: .
    ports:
      - 5000:5000
    volumes:
      - $HOME/Documents/qts:/home/docker/qts
    command:
      - /bin/bash
      - -c
      - sleep 60

使用 docker ps 找到您的容器 ID；

docker exec -it ID /bin/bash

和

ls
