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); });
