docker run -i -t image /bin/bash - source files first
提问by mattes
This works:
这有效：
# echo 1 and exit:
$ docker run -i -t image /bin/bash -c "echo 1"
1
# exit
# echo 1 and return shell in docker container:
$ docker run -i -t image /bin/bash -c "echo 1; /bin/bash"
1

Question: How could I sourcea file into the shell? (this does not work)
问题：我怎样才能把source一个文件放入shell？（这不起作用）
$ docker run -i -t image /bin/bash -c "source <(curl -Ls git.io/apeepg) && /bin/bash"
# content from http://git.io/apeepg is sourced and shell is returned

In my case, I use RUN sourcecommand (which will run using /bin/bash) in a Dockerfile to install nvm for node.js
就我而言，我RUN source在 Dockerfile 中使用命令（将使用 /bin/bash 运行）为 node.js 安装 nvm
Here is an example.
这是一个例子。
FROM ubuntu:14.04
RUN rm /bin/sh && ln -s /bin/bash /bin/sh
...
...
RUN source ~/.nvm/nvm.sh && nvm install 0.11.14

I wanted something similar, and expanding a bit on your idea, came up with the following:
我想要一些类似的东西，并扩展了你的想法，想出了以下内容：
docker run -ti --rm ubuntu \
bash -c 'exec /bin/bash --rcfile /dev/fd/1001 \
1002<&0 \
<<<$(echo PS1=it_worked: ) \
1001<&0 \
0<&1002'
--rcfile /dev/fd/1001will use that file descriptor's contents instead of .bashrc1002<&0saves stdin<<<$(echo PS1=it_worked: )putsPS1=it_worked:on stdin1001<&0moves this stdin to fd 1001, which we use as rcfile0<&1002restores the stdin that we saved initially
--rcfile /dev/fd/1001将使用该文件描述符的内容而不是 .bashrc1002<&0保存标准输入<<<$(echo PS1=it_worked: )穿上PS1=it_worked:标准输入1001<&0将此标准输入移动到 fd 1001，我们将其用作 rcfile0<&1002恢复我们最初保存的标准输入

You can use .bashrcin interactive containers:
您可以.bashrc在交互式容器中使用：
RUN curl -O git.io/apeepg.sh && \
echo 'source apeepg.sh' >> ~/.bashrc
Then just run as usual with docker run -it --rm some/image bash.
然后像往常一样运行docker run -it --rm some/image bash。
Note that this will onlywork with interactive containers.
请注意，这仅适用于交互式容器。

I don't think you can do this, at least not right now. What you could do is modify your image, and add the file you want to source, like so:
我认为你不能这样做，至少现在不能。您可以做的是修改您的图像，并添加您想要获取的文件，如下所示：
FROM image
ADD my-file /my-file
RUN ["source", "/my-file", "&&", "/bin/bash"]
