Docker compose失败

Question

我写了一个节点服务器，我想用docker compose来包装它进行开发(稍后我会添加更多的服务)。这是我的docker-compose.yml：

version: '3'

services:
    server:
        image: node:alpine
        volumes:
            - ./
        working_dir: /.
        environment:
            NODE_ENV: development
        ports:
            - 8009:8009
        command: npm run dev

当运行docker-compose up时，我得到：

Recreating bed_server_1 ... error

ERROR: for bed_server_1  Cannot start service server: OCI runtime create failed: container_linux.go:348: starting container process caused "open /proc/self/fd: no such file or directory": unknown

ERROR: for server  Cannot start service server: OCI runtime create failed: container_linux.go:348: starting container process caused "open /proc/self/fd: no such file or directory": unknown
ERROR: Encountered errors while bringing up the project.

我正在使用mac。你知道哪里出问题了吗？

Answer 1

由于音量的原因，可能会出现此错误。您应该尝试删除以下行：

volumes:
    - ./

然后尝试将该文件夹映射到docker-compose文件中声明的卷，如下所示：

services:
    server:
        image: node:alpine
        volumes:
            - test_volume:./
        working_dir: /.
        environment:
            NODE_ENV: development
        ports:
            - 8009:8009
        command: npm run dev
volumes:
    test_volume:
        external: true

Answer 2

卷应映射到容器内的文件夹。./没有说明文件夹在容器中的映射位置。也就是说，将卷更改为./:/app，以将./目录从主机映射到docker中的/app目录，并按如下所示更新working_dir：

        volumes:
            - ./:/app
        working_dir: /app
