docker - 我的Docker容器将从容器内运行命令，但不使用ENTRYPOINT

Question

如标题中所述-通过Dockerfile构建图像后，我可以通过run -i -t myimage /bin/bash输入图像，然后运行我想要的命令-它工作正常。

但是，在ENTRYPOINT ['mycommand']中执行Dockerfile不起作用。请看下面:

ENTRYPOINT ['/opt/torquebox/current/jruby/bin/torquebox']

CMD ["--help"]

/opt/torquebox/current/jruby/bin/torquebox --help在容器内工作，但从command not found炸毁(ENTRYPOINT)。

任何帮助，将不胜感激。

出于某种原因，ENTRYPOINT需要双引号。

更改了ENTRYPOINT ['/opt/torquebox/current/jruby/bin/torquebox']到ENTRYPOINT ["/opt/torquebox/current/jruby/bin/torquebox"]
它加载。
