Docker运行不正常，它要求至少一个参数 [英] Docker run not working it says requires at least 1 argument

问题描述

我正在学习docker，并尝试运行现有映像.第一个命令运行正常

I'm learning docker, and trying to run the existing images. The first command is working fine

命令1:docker run --name静态站点-e AUTHOR ="Mathi1" -d -P dockersamples/static-site

但是下面的命令抛出错误

But the below command is throwing error

命令2:docker run --name mvcdotnet -e AUTHOR ="Mathi2" -d -p valkyrion/mvcdotnet

错误:

"docker run"至少需要1个参数.

"docker run" requires at least 1 argument.

请参阅"docker run --help".

See 'docker run --help'.

用法:docker run [OPTIONS] IMAGE [COMMAND] [ARG ...]

Usage: docker run [OPTIONS] IMAGE [COMMAND] [ARG...]

在新容器中运行命令

推荐答案

根据 docker help run :

…
-p, --publish list                   Publish a container's port(s) to the host
-P, --publish-all                    Publish all exposed ports to random ports
…

命令1使用 -P (-publish-all 的缩写)，然后使用图像名称. -P 没有参数.命令2使用 -p (-发布列表的缩写). -p 需要一个参数，我认为docker将图像名称误认为是 -p 的参数(并在之后使用图像名称).

Command 1 uses -P (short form of --publish-all) and after that the image name. -P has no arguments. Command 2 uses -p (short form of --publish list). -p expects an argument and I think docker mistakes the image name as the argument for -p (and expects an image name after that).
