Question

我想在我的R工作中使用旧R版本的Docker映像。所以我用-

docker pull rocker/verse:3.3.2

现在我要以-

的形式运行此docker映像

docker run rocker/verse:3.3.2

这给出了以下响应-

[fix-attrs.d] applying owners & permissions fixes...
[fix-attrs.d] 00-runscripts: applying... 
[fix-attrs.d] 00-runscripts: exited 0.
[fix-attrs.d] done.
[cont-init.d] executing container initialization scripts...
[cont-init.d] add: executing... 
Nothing additional to add
[cont-init.d] add: exited 0.
[cont-init.d] userconf: executing... 


ERROR: You must set a unique PASSWORD (not 'rstudio') first! e.g. run with:
docker run -e PASSWORD=<YOUR_PASS> -p 8787:8787 rocker/rstudio


[cont-init.d] userconf: exited 1.
[cont-init.d] done.
[services.d] starting services
[services.d] done.

此后，它停止响应。

我也尝试过使用以下密码-

sudo docker run -e PASSWORD=abc$ -p 8787:8787 rocker/verse:3.3.2
[fix-attrs.d] applying owners & permissions fixes...
[fix-attrs.d] 00-runscripts: applying... 
[fix-attrs.d] 00-runscripts: exited 0.
[fix-attrs.d] done.
[cont-init.d] executing container initialization scripts...
[cont-init.d] add: executing... 
Nothing additional to add
[cont-init.d] add: exited 0.
[cont-init.d] userconf: executing... 
[cont-init.d] userconf: exited 0.
[cont-init.d] done.
[services.d] starting services
[services.d] done.

但是在那之后，即使经过1个小时，我也看不到任何进展。

有什么办法可以通过docker image使用旧的R版本？

谢谢

问题是您没有告诉容器做任何事情。我可以像这样运行一个交互式R终端，因此它似乎正在工作：

$ docker run --rm -it rocker/verse:3.3.2 R

R version 3.3.2 (2016-10-31) -- "Sincere Pumpkin Patch"

注意，我在R通话结束时传递了docker run命令。结合-it标志，这将在容器内部打开一个交互式R终端。如您所见，交互式R终端正在运行3.3.2版本。

无论如何，此图像似乎工作正常，您只需要决定要使用它做什么即可。

另一个选择是传递bash而不是R，然后从那里运行命令。另一个选择是在项目中创建一个Dockerfile，在该项目中使用该图像FROM，并在构建时将R脚本复制到容器中。这里有太多可供选择的选项，但我想您明白了。
