Docker 部署 2048游戏网站

2018-05-23

1. 2048游戏网站的快速搭建

操作	命令
在线仓库寻找dao-2048镜像
将注册/仓库服务器上的镜像下载到本地
显示本地已有镜像
显示docker的系统信息
将dao-2048镜像运行在内存中，创建并运行容器 2048，放在后台运行，映射80端口

2. 熟悉Docker容器命令

操作	命令
停止容器2048
启动容器2048
查看容器2048日志
查看当前正在运行或之前运行过的容器
在当前运行的容器2048里新建文档/test.txt
查看容器2048运行中的存储资源变化
将宿主机上的文件/tmp/file.out拷贝到容器2048中的/etc目录下，并验证
将容器2045中的/etc/hosts文件拷贝到宿主机/tmp目录下，并验证
更新镜像dao-2048的名称标记为dao-2048:0.01
从修改过的容器2048创建新的镜像dao-2048:0.02，也叫做容器固化
导出容器2048的文件系统到一个2048.tar包归档文件中
再次停止容器2048
删除容器2048

3. 熟悉Docker镜像命令

操作	命令
删除镜像dao-2048
将dao-2048:0.02镜像在本地保存为dao.tar镜像包
删除镜像 dao-2048:0.02
再将刚才保存的dao.tar镜像文件重新装载到本地系统
显示本地已有镜像
