我在MacOSX上使用Docker(带有Boot2Docker)。
我可以从Docker Hub运行映像。
但是,当我尝试像这样运行自己的映像之一时:
docker run -P mylocalimage
要么
docker run -P mylocalimage bin/a3-write-back
...
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,但是为什么呢?
基本图像是 errordeveloper/oracle-jdk
errordeveloper/oracle-jdk
谢谢你的帮助。

您的图片基于不带bash外壳的busybox。它的确有外壳/bin/sh。
/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
但这确实是:
$ docker run -it busybox /bin/sh / #
由于您的入口点脚本,可能还会带来更多复杂性,但是您始终可以覆盖它。
