本文介绍了Docker Volume 没有挂载任何文件的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我正在尝试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 并在工作时使用我的本地文件.

使用运行命令:

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

使用我的Dockerfile 

FROM python:3.5.1工作目录/var/dynamo运行 pip3 安装龙卷风曝光 8001

但是，当我 bash 进入容器 docker exec -it dynamo/bin/bash 并运行 ls -la 时，目录 是空的！

root@7d3d338891aa:/var/dynamo# ls -la共 4 个drwxr-xr-x 2 根根 40 Dec 29 03:37 .drwxr-xr-x 24 根 4096 12 月 29 日 03:36 ..

运行 docker inspect dynamo 显示正确挂载的目录

Docker 版本为 1.9.1

解决方案

Docker &Virtualbox 似乎在将卷挂载到/Users 目录之外时遇到问题.解决此问题的唯一方法是删除 docker 机器映像，将/Users/yourname 目录正确设置为 Virtualbox 中的共享文件夹，然后创建一个新的 docker 机器映像.

解决问题的步骤:

  1. docker-machine stop dev
  2. docker-machine rm dev
  3. docker-machine create --driver virtualbox dev
  4. eval "$(docker-machine env dev)"
  5. docker build -t davesrepo/dynamo -f ./Dockerfile .
  6. docker run -v $(pwd):/var/dynamo -d -t -p 8001:8001 --env-file ./dynamo.env --name dynamo davesrepo/dynamo
  7. docker exec -it dynamo/bin/bash
  8. ls

文件！

I'm trying to mount my source files to a directory in docker located at /var/dynamo. I'd like to be able to run Docker locally and use my local files as I am working.

with the run command: 

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

with my Dockerfile 

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

However, when I bash into the container docker exec -it dynamo /bin/bash and run ls -la the directory is empty!

root@7d3d338891aa:/var/dynamo# ls -la
total 4
drwxr-xr-x  2 root root   40 Dec 29 03:37 .
drwxr-xr-x 24 root root 4096 Dec 29 03:36 ..

Running docker inspect dynamo shows the directory mounted properly

Docker version is 1.9.1

解决方案

Docker & Virtualbox seem to have an issue with mounting a volume outside of the /Users directory. The only way to fix the issue is to delete the docker machine image, properly set the /Users/yourname directory as the share folder in Virtualbox and create a new docker machine image.

Steps to fix the issue:

  1. docker-machine stop dev
  2. docker-machine rm dev
  3. docker-machine create --driver virtualbox dev
  4. eval "$(docker-machine env dev)"
  5. docker build -t davesrepo/dynamo -f ./Dockerfile .
  6. docker run -v $(pwd):/var/dynamo -d -t -p 8001:8001 --env-file ./dynamo.env --name dynamo davesrepo/dynamo
  7. docker exec -it dynamo /bin/bash
  8. ls
