Status: Downloaded newer image for training/webapp:latest启动docker app
docker run -d -P training/webapp python app.py
Usage:
* -d daemon 后台运行模式
* -P 将容器内部使用的网络端口映射到我们使用的主机上。
查看docker进程
docker ps -l
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
c47561fa4f2b training/webapp "python app.py" 7 seconds ago Up 6 seconds 0.0.0.0:32768->5000/tcp agitated_ardinghelli这里是container id是之后进行操作的唯一标示；这里的PORTS是本地32768端口映射到来docker里面的5000端口。这里可以访问浏览器http://localhost:32768 ，可以看到hello world 的信息：
docker stop container_id
停掉container_id
docker start container_id
启动container_id
查看信息
docker port container_id
查看container 的端口映射, docker port –> local system port,信息输出：
5000/tcp -> 0.0.0.0:32768
docker logs -f container_id
查看container的日志，示例结果输出：
docker logs -f c47561fa4f2b
