在Docker(tidyverse)中挂载R/RStudio可访问的本地卷 [英] Mount local volume accessible to R/RStudio in docker (tidyverse)

问题描述

关于如何从docker容器内部寻址本地文件夹有很多鲜为人知的问题，但是我找不到与我的容器完全匹配的一个，因此这里有另外一个:

如何运行Docker容器并安装本地文件夹，以便R/RStudio可以在容器内部对其进行访问?

这听起来像是:

我确定我缺少基本的知识，但是如果有人可以告诉我那是什么...谢谢！

解决方案

在这种情况下，R和RStudio的默认工作目录为/home/rstudio ，比/下两级，我告诉docker挂载文件夹的地方.

在问题中执行 docker run 命令后，您可以转到 list.files('/')来查看文件夹.

如果要像我一样将文件夹显示在R的默认工作目录中，请按如下所示修改 docker run :

  docker run -d -p 8787:8787 -v $ HOME/my_folder:/home/rstudio/LOOKATMEEE -e ROOT = TRUE跷板/tidyverse:3.4 

在那里应该是:

There are a ton of little-upvoted questions about how to address local folders from inside a docker container, but I can't find one that quite matches mine, so here goes another one:

How can I run a docker container, and mount a local folder so that it's accessible by R/RStudio, inside the container?

That sounds kind of like: mounting local home directory in Rstudio docker? and using an approach similar to that, I can start a container and mount a volume:

docker run -d -p 8787:8787 -v $HOME/my_folder:/LOOKATMEEE -e ROOT=TRUE rocker/tidyverse:3.4

and if I run a bash shell in the container, I can see the folder:

docker exec -it 38b2d6ca427f bash

> ls
bin   dev  home  lib    LOOKATMEEE  mnt  proc  run   srv  tmp  var  boot  etc  init  lib64  media       opt  root  sbin  sys  usr
#                       ^ there is is!

But if I go connect to RStudio server at localhost:8787, I don't see it in the files pane, nor does it show up when run list.files() in the R console:

I'm sure I'm missing something basic, but if someone can tell me what that is... thank you!

解决方案

In this circumstance, R and RStudio have a default working directory of /home/rstudio, two levels down from /, where I was telling docker to mount the folder.

After the docker run command in the question, you can go list.files('/') to see the folder.

If you want your folder to show up in the default working directory for R, as I do, then modify docker run like this:

docker run -d -p 8787:8787 -v $HOME/my_folder:/home/rstudio/LOOKATMEEE -e ROOT=TRUE rocker/tidyverse:3.4

and there it shall be:
