（二）docker的部署安裝，配置，基礎命令

1、docker 的安裝部署

這裏不過多介紹，下面這兩個linux髮型版 安裝能夠參考

ubuntu的 docker-ce安裝

centos7的 docker-ce安裝

二.docker配置文件

重要參數解釋：

OPTIONS 用來控制Docker Daemon進程參數
-H 表示Docker Daemon綁定的地址， -H=unix:///var/run/docker.sock -H=tcp://0.0.0.0:2375
--registry-mirror表示Docker Registry的鏡像地址--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是否開啓SELinux，默認開啓 --selinux-enabled=true
--bip 表示網橋docker0使用指定CIDR網絡地址，--bip=172.17.42.1
-b 表示採用已經建立好的網橋， -b=xxx
重要參數解釋：
OPTIONS=-H=unix:///var/run/docker.sock -H=tcp://0.0.0.0:2375 --registrymirror=http://4bc5abeb.m.daocloud.io
--selinux-enabled=true
下面是代理的設置
http_proxy=xxxxx:8080
https_proxy=xxxxxx:8080

docker run [OPTIONS] IMAGE[:TAG] [COMMAND] [ARG...]

docker run後面追加-d=true或者-d，那麼容器將會運行在後臺模式。
docker exec來進入到到該容器中，或者attach從新鏈接容器的會話

[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

 

決定容器的運行方式，前臺執行仍是後臺執行

進行交互式操做（例如Shell腳本），那咱們必須使用-i -t參數同容器進行數據交互

docker run時沒有指定--name，那麼deamon會自動生成一個隨機字符串UUID

Docker時有自動化的需求，你能夠將containerID輸出到指定的文件中（PIDfile）： --cidfile="" --cidfile=""

Docker的容器是沒有特權的，例如不能在容器中再啓動一個容器。這是由於默認狀況下容器是不能訪問任何其它設 備的。可是經過"privileged"，容器就擁有了訪問任何其它設備的權限。
