运行docker容器

运行一个 centos 容器
The -i and -t flags can be passed to the exec command to keep an interactive shell open, and you can specify the shell you want to attach after the container ID.

[root@localhost ~]# docker run  -i -t centos /bin/bash
Unable to find image 'centos:latest' locally
latest: Pulling from library/centos

Status: Downloaded newer image for centos:latest

运行 docker 以 daemon 方式运行,host 开放端口 5001,对应容器内端口 5000
The -p means “publish ports”

docker run -d -p 5001:5000 python-flask
