Question

Dockerfile

FROM node:9.4
WORKDIR /app
COPY package.json /app
COPY . /app
CMD node app.js
EXPOSE 80

节点/快速代码

var socket_number = 80
var express = require('express');
var app = express();
....
var http = require('http').Server(app);
var io = require('socket.io')(http);
http.listen(socket_number);

生成

C:\Users\john_\Documents\GitHub\purple_cloud>docker run 171b2830a121 -p 3000:80
docker: Error response from daemon: OCI runtime create failed: container_linux.go:296: starting container process caused “exec: “-p”: executable file not found in $PATH”: unknown.

问题

我做错了什么？

观察

docker run 171b2830a121没有＆＃34; -p 3000:80＆＃34;不会产生错误，但无法访问端口80或3000。

节点app.js ...正常工作

Answer 1

您需要重新安排docker run的参数。假设您的图片名称为171b2830a121，则应为：

docker run -p 3000:80 171b2830a121

Docker暴露端口 - OCI运行时创建失败
