问题描述
我正在尝试将源文件安装到位于/var/dynamo的Docker目录中.我希望能够在本地运行Docker并在工作时使用本地文件.
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.
使用run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
WORKDIR /var/dynamo
RUN pip3 install tornado
EXPOSE 8001
但是，当我猛击到容器docker exec -it dynamo /bin/bash并运行ls -la时，目录是空的！
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 ..
运行docker inspect dynamo显示目录已正确安装
Running docker inspect dynamo shows the directory mounted properly

推荐答案
Docker& Virtualbox在/Users目录之外挂载卷似乎存在问题.解决此问题的唯一方法是删除docker机器映像，在Virtualbox中正确设置/Users/yourname目录作为共享文件夹，然后创建一个新的docker机器映像.
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.
解决此问题的步骤:
-
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 $(pwd):/var/dynamo -d -t -p 8001:8001 --env-file ./dynamo.env --name dynamo davesrepo/dynamo -
docker exec -it dynamo /bin/bash -
ls
docker-machine stop devdocker-machine rm devdocker-machine create --driver virtualbox deveval "$(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/dynamodocker exec -it dynamo /bin/bashls
