关于docker 基础使用记录

Docker Hub地址：https://hub.docker.com

Docker Hub 存放着 Docker 及其组件的所有资源。Docker Hub 可以帮助你与同事之间协作，并获得功能完整的 Docker。为此，它提供的服务有：

Docker 镜像主机
用户认证
自动镜像构建和工作流程工具，如构建触发器和 web hooks
整合了 GitHub 和 BitBucket

常用的命令和功能记录：

1.docker search http //查询镜像 ，http为镜像名称
2.docker pull  http    //下载镜像
3.docker images ls //查看本地所有存在的镜像
4.docker ps -a //查看本地 开启或未开启的镜像
5.docker run http //启动一个镜像
6.docker run -t -i http /bin/bash  //交互式启动镜像 -t代表伪终端 -i代表标准输入  exit；可以推出容器，默认退出后容器关闭
7.docker start http  //启动此镜像  stop为停止
8.docker run -d http //指定镜像后台运行
9. docker exec -t -i http bash  //进入容器
10.docker export fe523b5ce4e8 >ubuntu.tar //导出容器到本地
11.cat ubuntu.tar |ocker import - test/ubuntu:v1.0 //导入容器快照

实例操作：

1.根据镜像创建一个容器

[root@localhost ~]# docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
hopeful_austin      latest              b373750484ee        About an hour ago   133.3 MB
docker.io/ubuntu    12.04               5b117edd0b76        9 months ago        103.6 MB
[root@localhost ~]# docker run -t -i docker.io/ubuntu:12.04
root@8b0042551f59:/# ifconfig
bash: ifconfig: command not found

2.安装一些命令，然后保存我更新后的镜像，并根据保存的新镜像进入查看是否存在我安装的命令

root@8b0042551f59:/# apt-get update
root@8b0042551f59:/# apt-get install net-tools

3.将保存后的镜像传到docker hub上备份

[root@localhost ~]# docker ps -a
CONTAINER ID        IMAGE                    COMMAND             CREATED             STATUS                       PORTS               NAMES

4.删除本地镜像，查找我docker hub上的的镜像并下载

[root@localhost ~]# docker rmi quanl/unbuntu:v9

[root@localhost ~]# docker exec -ti 9c3348840322 bash

设置ssh登录docker

[root@localhost ~]# docker run -ti -p2022:22 --name="ubuntu_rom" --privileged=true -v /letv/Android/:/letv/Android/ yeming_rom /bin/bash

关闭宿主机的selinux 和 iptables 即可登录到docker系统内

ubuntu系统安装后没有ifconfig和ping命令解决：

apt-get install net-tools
apt-get install iputils-ping
