一、docker 的安装部署
这里不过多介绍，下面这两个linux发型版 安装可以参考
二.docker配置文件
重要参数解释：
OPTIONS 用来控制Docker Daemon进程参数
-H 表示Docker Daemon绑定的地址， -H=unix:///var/run/docker.sock -H=tcp://0.0.0.0:2375
--registry-mirror表示Docker Registry的镜像地址--registry-mirror=http://4bc5abeb.m.daocloud.io
--insecure-registry表示（本地）私有Docker Registry的地址， --insecure-registry ${pivateRegistyHost}:
--selinux-enabled是否开启SELinux，默认开启 --selinux-enabled=true
--bip 表示网桥docker0使用指定CIDR网络地址，--bip=172.17.42.1
-b 表示采用已经创建好的网桥， -b=xxx
重要参数解释：
OPTIONS=-H=unix:///var/run/docker.sock -H=tcp://0.0.0.0:2375 --registrymirror=http://4bc5abeb.m.daocloud.io
--selinux-enabled=true
下面是代理的设置
http_proxy=xxxxx:
https_proxy=xxxxxx:

docker run [OPTIONS] IMAGE[:TAG] [COMMAND] [ARG...]
docker run后面追加-d=true或者-d，那么容器将会运行在后台模式。
docker exec来进入到到该容器中，或者attach重新连接容器的会话
[root@docker ~]# docker run -it java java -version
openjdk version "1.8.0_111"
OpenJDK Runtime Environment (build 1.8.0_111-8u111-b14-~bpo8+-b14)
OpenJDK -Bit Server VM (build 25.111-b14, mixed mode)
[root@docker ~]# docker run -it java uname
Linux
[root@docker ~]# docker run -it java ps
PID TTY TIME CMD
pts/ :: ps
决定容器的运行方式，前台执行还是后台执行
进行交互式操作（例如Shell脚本），那我们必须使用-i -t参数同容器进行数据交互
docker run时没有指定--name，那么deamon会自动生成一个随机字符串UUID
Docker时有自动化的需求，你可以将containerID输出到指定的文件中（PIDfile）： --cidfile="" --cidfile=""
Docker的容器是没有特权的，例如不能在容器中再启动一个容器。这是因为默认情况下容器是不能访问任何其它设 备的。但是通过"privileged"，容器就拥有了访问任何其它设备的权限。
