当我运行我的docker容器时,它似乎只是尊重CMD数组的第一个元素(python可执行文件)并忽略尾随参数。
Dockerfile:
$ docker run --rm -it --volume $(pwd)/..:/mycode --volume mycontainer-virtualenv:/virtualenv mycontainer
运行命令:
Python 3.4.3 (default, Oct 14 2015, 20:28:29)
[GCC 4.8.4] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>>
输出:
--detach
如果我运行-it
而非$ docker run --rm -it --volume $(pwd)/..:/mycode --volume mycontainer-virtualenv:/virtualenv mycontainer /virtualenv/bin/python /mycode/myscript.py --param1
Python 3.4.3 (default, Oct 14 2015, 20:28:29)
[GCC 4.8.4] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>>
,则会发生同样的情况。
如果我使用CMD作为重写的docker run参数运行,也会发生同样的事情:
$ docker run --rm -it --volume $(pwd)/..:/mycode --volume mycontainer-virtualenv:/virtualenv mycontainer bash
root@d6a990e81c22:/# /virtualenv/bin/python /mycode/myscript.py --param1
Hello world!
如果我使用bash运行容器并从bash提示符运行CMD,它可以正常工作:
if self.isKindOfClass(RightViewController.classForCoder()) {
let controller: RightViewController = self as! RightViewController
}

你可能想要
$pdf->Image($profile,10,'',30);
而不是
CMD ["/virtualenv/bin/python /mycode/myscript.py --param1"]
当Dockerfile中存在CMD ["/virtualenv/bin/python", "/mycode/myscript.py", "--param1"]
和CMD
时,CMD将作为ENTRYPOINT的默认参数。所以你基本上做了
ENTRYPOINT
何时需要
bash -c "/virtualenv/bin/python" "/mycode/myscript.py" "--param1"
