mac os docker build dockerfile volume 目录创建失败?

Question

FROM ubuntu:16.04
VOLUME ["/root/share1","/root/share2"]

docker build -f ./dockerfile -t ubuntu-volume-test:16.04 .

docker inspect 之后的结果,容器内的share1,share2创建完成，可是我的机器的目录竟然没有创建,Volumes字段是空的

    "Config": {
        "Hostname": "53f0d054bf0b",
        "Domainname": "",
        "User": "",
        "AttachStdin": true,
        "AttachStdout": true,
        "AttachStderr": true,
        "Tty": true,

        "StdinOnce": true,
        "Env": [
            "PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"
        ],
        "Cmd": [
            "/bin/sh",
            "-c",
            "/bin/bash"
        ],
        "Image": "ubuntu-volume-test:16.04",
        "Volumes": {
            "/root/share1": {},
            "/root/share2": {}
        },
        "WorkingDir": "",
        "Entrypoint": null,
        "OnBuild": null,
        "Labels": {}
    },

Answer 1

image 里不会有本机目录。

本机得在 docker run 的时候指定。
