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图像时:
docker run -P mylocalimage
或
docker run -P mylocalimage bin/a3-write-back
或
...
我明白了:
docker "env: can't execute 'bash': No such file or directory"
我猜它找不到要在容器中执行的bash二进制文件,但为什么呢?
基本图片为errordeveloper/oracle-jdk
感谢您的帮助。
阿什利。

您的图片基于busybox,它没有bash shell。它在/bin/sh
处有一个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化,但您始终可以覆盖它。
答案 1 :(得分:0)
如果您的图像具有定义的入口点,这将不起作用。对于这些情况,请使用: ' docker run -it --entrypoint /bin/bash '
答案 2 :(得分:0)
如果您的图像定义了 ENTRYPOINT,如何使用 bash 覆盖 docker run:
docker run -it --entrypoint /bin/bash <your-image>
