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，当我试图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" 

我猜它不能find一个在容器中执行的bash二进制文件，但是为什么？

基本映像是errordeveloper/oracle-jdk

谢谢你的帮助。

阿什利。

您的图像基于busybox，它没有bash shell。 它在/bin/sh有一个shell。

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 / # 

由于您的入口点脚本可能会有进一步的复杂性，但您始终可以覆盖该脚本。
