为什么Docker说它不能执行'bash'?

我在MacOSX上使用Docker(使用Boot2Docker)。

我可以从Docker Hub运行图像。

但是,当我尝试运行我自己的一个像这样的图像:

docker run -P mylocalimage

要么:

docker run -P mylocalimage bin/a3-write-back

要么:

...

我得到:

docker "env: can't execute 'bash': No such file or directory"

我猜它找不到在容器中执行的bash二进制文件,但为什么?基本图像是 errordeveloper/oracle-jdk。

你的图像基于busybox,它没有bash shell。它的确有一个shell /bin/sh

所以这不起作用:

$ docker run -it busybox bash
exec: "bash": executable file not found in $PATH2015/01/15 11:09:08 Error response from daemon: 
Cannot start container a5074af2f81f8cc1eb0076f4ec9ada5f87be1440006f54a9b06ab701fc60176a: exec:  
"bash": executable file not found in $PATH

但是这样做:

$ docker run -it busybox /bin/sh
/ #
