Docker卷没有安装任何文件

我试图将我的源文件挂载到位于/ var / dynamo的docker目录中。 我希望能够在本地运行Docker并在我工作时使用我的本地文件。

用运行命令：

docker run -v $(pwd):/var/dynamo -d -t -p 8001:8001 --name dynamo davesrepo/dynamo

与我的Dockerfile

FROM python:3.5.1 workdir /var/dynamo RUN pip3 install tornado EXPOSE 8001

但是，当我撞到容器docker exec -it dynamo /bin/bash并运行ls -la目录是空的！

运行docker inspect dynamo显示正确安装的目录

在Windows Server 2016 TP4上安装Docker

使用Docker for Windows Installer v1.6.0安装的Boot2Docker在start.sh中的“第36行：cd：HOME not set”

Docker＆VirtualBox在/ Users目录之外安装一个卷似乎有问题。 解决此问题的唯一方法是删除Docker计算机映像，将/ Users / yourname目录正确设置为VirtualBox中的共享文件夹，并创建一个新的Docker计算机映像。

步骤来解决这个问题：

docker-machine stop dev

docker-machine rm dev

docker-machine create --driver virtualBox dev

eval "$(docker-machine env dev)"

docker build -t davesrepo/dynamo -f ./Dockerfile .

docker run -v $(pwd):/var/dynamo -d -t -p 8001:8001 --env-file ./dynamo.env --name dynamo davesrepo/dynamo

docker exec -it dynamo /bin/bash

ls

root@42f9e47fa2de:/var/dynamo# ls Dockerfile README.md __init__.py __pycache__ bin config.ini requirements.txt seed.sql tests

文件！

这很奇怪。 我试图用我的docker 1.6.0检查这个问题，所以我创建了一个图像similair给你的：

FROM ubuntu:utopic workdir /var/dynamo EXPOSE 8001

然后，我将$(pwd)装载到容器中，并且能够在主机文件系统和容器之间交换文件：

➜ ololo echo $(pwd) /tmp/ololo ➜ ololo ls Dockerfile kikiboi ➜ ololo docker run --rm -it -v $(pwd):/var/dynamo volume_issue bash root@9b15875997ba:/var/dynamo# ls Dockerfile kikiboi root@9b15875997ba:/var/dynamo# touch container_file root@9b15875997ba:/var/dynamo# exit ➜ ololo ls container_file Dockerfile kikiboi

还需要确保主机上的/Users/dave/Sites/davesrepo/dynamo和容器内的/var/dynamo具有相同的inode编号。 使用stat实用程序：

➜ ~ stat -c %i /tmp/ololo 1835031 ➜ ~ docker run --rm -it -v /tmp/ololo:/var/dynamo ubuntu:utopic stat -c %i /var/dynamo 1835031

我使用1.9，这工作正常：

Docker run -d -t --restart=on-failure:3 -h docker_console -p 8880:80 -v ~/docker_console/var/www:/var/www --name docker_console repo/docker_console

它将主机上的〜/ docker_console / var / www连接到容器中的/ var / www。 如果你使用目录名而不是变量呢？
