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}:5000 --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:8080 https_proxy=xxxxxx:8080

docker pull 从镜像站拉取镜像 tag：latest 标签为 最新

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-b14-2~bpo8+1-b14) OpenJDK 64-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 1 pts/0 00:00:00 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。
