是否可以评估docker env_file中的shell命令（在主机上执行）？

Question

I run a docker container with docker run --env-file envfile image . envfile contains environment variables like LISTEN=localhost:12345 , SSH_USER=jannis , etc.

I tried adding a variable as follows: SSH_PRIVATE_KEY=`cat ~/.ssh/id_rsa` . I expected Docker to execute the command in $() on the host machine and set the variable to its output; however, Docker just set the variable literally. Is there a way to do this?

在编写此代码时，我认为我可以让执行的Shell为我完成工作，然后传递--env SSH_PRIVATE_KEY=`cat ~/.ssh/id_rsa` 。
