Question

我用docker-compose来容器化！我的服务。这是一个描述有问题容器的片段：

version: '2'
services:
    rabbit:
        hostname: rabbit
        image: rabbitmq:latest
        environment:
            - RABBITMQ_DEFAULT_USER=admin
            - RABBITMQ_DEFAULT_PASS=mypass
        ports:
            - "5672:5672"
        restart: unless-stopped
    redis:
        image: redis:3.2.8
        restart: unless-stopped

    worker_robot:
        image: myservice:latest
        depends_on:
            - rabbit
            - redis
        environment:
            - type_env=robot
        cap_add:
            - SYS_ADMIN
        privileged: true
        restart: unless-stopped

    service:
        image: myservice:latest
        volumes:
            - /etc/media:/app/static
            - /etc/media:/app/media
        depends_on:
            - redis
            - rabbit
        environment:
            - type_env=service
        ports:
            - "8998:8000"
        cap_add:
            - SYS_ADMIN
        privileged: true
        restart: unless-stopped

    swagger:
        image: myswagger:latest
        ports:
            - "3998:8080"
        restart: unless-stopped

在/etc/media我有很多（~10 ^ 9）个文件，当我运行docker-compose up然后docker logs service_1时，我会看到类似这样的内容：

Copying '/app/media/images/instance-image/d02049.jpg'...

似乎docker正在将所有文件复制到某个地方。我不需要从docker容器中的这个共享文件夹中读取任何内容，只是希望容器向它们添加内容。有没有办法阻止复制这些内容？

Answer 1

Docker不会复制任何文件，也不会将任何日志写入服务日志。您在docker logs service_1中看到的只是myservice:latest入口点的输出（STDERR / STDOUT）。

在docker-compose中使用docker卷而不将卷数据复制到容器
