node.js - 运行 docker image 不起作用

Question

我是 Docker 的新手，我正在学习 Docker 的 Node.js 教程。我卡在了这一步:http://docs.docker.io/en/latest/examples/nodejs_web_app/#building-your-image

我已经执行了这个:

$ docker build -t user/centos-node-hello .
...
Successfully built c04aea889b03

构建成功。

$ docker images

现在我尝试运行图像:

$ docker run -p 49160:8080 -d user/centos-node-hello
995bfeef4edd723027480fdb43f097e2ba6a97b8fb1d2e9ec679dc1247f68a84

但是如果我检查进程，实例没有运行。

$ docker ps
CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS             PORTS  

有什么想法吗？谢谢。

Answer 1

尝试:docker run -p 49160:8080 -i -t/centos-node-hello/bin/bash
