创建/root/myapp目录
[root@xbldockerbuild myapp]# tree /root/myapp /root/myapp ├── Dockerfile └── src └── app.js 1 directory, 2 files
其中app.js和Dockerfile 内容如下
[root@xbldockerbuild myapp]# cat src/app.js
var http=require('http');
var ports = [7006, 7007, 7008, 7009];
var servers = [];
var s;
function reqHandler(req, res) {
var serPort=req.socket.localPort;
res.writeHead(200, {'Content-Type':'text/plain'});
res.write('Listening on port ' + serPort);
res.end();
}
ports.forEach(function(port) {
s = http.createServer(reqHandler);
s.listen(port);
servers.push(s);
});[root@xbldockerbuild myapp]# cat Dockerfile FROM alpine:3.8 RUN apk update RUN apk add --no-cache nodejs COPY ./src /app CMD ["/usr/bin/node", "/app/app.js"] EXPOSE 7006/tcp EXPOSE 7007/tcp EXPOSE 7008/tcp EXPOSE 7009/tcp
docker build 制作容器镜像

创建容器测试
[root@xbldockerbuild myapp]# docker run -d -it --name httpserver alpine-node-multiple-ports:v1 d511b5157cbdc40da55623cbf6a3c20a0317eac3e52c3239236ae1c514536044 [root@xbldockerbuild myapp]# docker ps -a |grep httpserver d511b5157cbd alpine-node-multiple-ports:v1 "/usr/bin/node /ap..." 27 seconds ago Up 26 seconds 7006-7009/tcp httpserver [root@xbldockerbuild myapp]# docker inspect httpserver | grep IPAddress "SecondaryIPAddresses": null, "IPAddress": "172.17.0.6", "IPAddress": "172.17.0.6", [root@xbldockerbuild myapp]# curl http://172.17.0.6:7006/ Listening on port 7006 [root@xbldockerbuild myapp]# curl http://172.17.0.6:7007/ Listening on port 7007 [root@xbldockerbuild myapp]# curl http://172.17.0.6:7008/ Listening on port 7008 [root@xbldockerbuild myapp]# curl http://172.17.0.6:7009/ Listening on port 7009
