手动构建Docker镜像

1、运行一个容器，并且在容器中安装和配置nginx

[root@docker /]# docker run --name nginx-man -it centos
[root@37d5b354b661 /]# yum install -y wget gcc gcc-c++ make openssl-devel
[root@37d5b354b661 /]# wget http://nginx.org/download/nginx-1.9.11.tar.gz
--2016-02-24 06:14:44--  http://nginx.org/download/nginx-1.9.11.tar.gz
Resolving nginx.org (nginx.org)... 95.211.80.227, 206.251.255.63, 2001:1af8:4060:a004:21::e3, ...

[root@37d5b354b661 /]# cd /usr/local/src 
[root@37d5b354b661 src]# tar zxvf pcre-8.38.tar.gz 
[root@37d5b354b661 src]# tar zxvf nginx-1.9.11.tar.gz 
[root@37d5b354b661 src]# useradd -s /sbin/nologin -M www
[root@37d5b354b661 src]# pwd
/usr/local/src
[root@37d5b354b661 src]# ls 
nginx-1.9.11  nginx-1.9.11.tar.gz  pcre-8.38  pcre-8.38.tar.gz
[root@37d5b354b661 src]# cd nginx-1.9.11
[root@37d5b354b661 nginx-1.9.11]# ./configure --prefix=/usr/local/nginx --user=www --group=www --with-http_ssl_module --with-http_stub_status_module --with-pcre=/usr/local/src/pcre-8.38
[root@37d5b354b661 nginx-1.9.11]# make
[root@37d5b354b661 nginx-1.9.11]# make install
[root@37d5b354b661 nginx-1.9.11]# echo $?
[root@37d5b354b661 nginx-1.9.11]# vi /usr/local/nginx/conf/nginx.conf

添加信息：

daemon off；

允许后台允许nginx：

[root@37d5b354b661 nginx-1.9.11]# echo "daemon off;">>/usr/local/nginx/conf/nginx.conf
设置开机自动启动(经过测试发现不能自动生效）：
[root@37d5b354b661 nginx-1.9.11]# vi /etc/rc.local         
[root@37d5b354b661 nginx-1.9.11]# echo "/usr/local/nginx/sbin/nginx">>/etc/rc.local

2、将配置好的容器，当作一个镜像进行手动提交（wanlong/my-nginx:v3）：

[root@docker ~]# docker ps -l
CONTAINER ID        IMAGE                 COMMAND             CREATED             STATUS              PORTS               NAMES
494d0139baf9        wanlong/my-nginx:v2   "/bin/bash"         6 minutes ago       Up 6 minutes                            lonely_curie        
[root@docker ~]# docker commit -m "my nginx" 494d0139baf9 wanlong/my-nginx:v3
76507d1d9b41a5189eddd641f2ecbc1b19516eb83d8215dddc73887ca49f4bef
[root@docker ~]# docker images
REPOSITORY                   TAG                 IMAGE ID            CREATED             VIRTUAL SIZE
wanlong/my-nginx             v3                  76507d1d9b41        5 seconds ago       517.2 MB

lemonbar/centos6-ssh         latest              b78c71c001db        19 months ago       296.9 MB

3、使用提交过的镜像，运行新的容器

[root@docker ~]# docker run -d -p 9999:80 wanlong/my-nginx:v3 /usr/local/nginx/sbin/nginx
656058dc0375d3a88ebb8407e64f10542c95e5185b9335c0e50ae1de0be0cee2
[root@docker ~]# docker ps -l
CONTAINER ID        IMAGE                 COMMAND                CREATED             STATUS              PORTS                  NAMES
656058dc0375        wanlong/my-nginx:v3   "/usr/local/nginx/sb   8 seconds ago       Up 6 seconds        0.0.0.0:9999->80/tcp   backstabbing_thompson   
[root@docker ~]# docker ps
CONTAINER ID        IMAGE                 COMMAND                CREATED             STATUS              PORTS                    NAMES
656058dc0375        wanlong/my-nginx:v3   "/usr/local/nginx/sb   8 minutes ago       Up 8 minutes        0.0.0.0:9999->80/tcp     backstabbing_thompson   
494d0139baf9        wanlong/my-nginx:v2   "/bin/bash"            17 minutes ago      Up 17 minutes                                lonely_curie            
37d5b354b661        centos                "/bin/bash"            2 hours ago         Up 2 hours                                   nginx-man               
94ea720a2c41        centos                "/bin/bash"            4 hours ago         Up 4 hours                                   volume-test04           
8884fc392971        nginx                 "nginx -g 'daemon of   18 hours ago        Up 6 hours          80/tcp, 443/tcp          nginxdocker             
14caa9ab03a9        dockerui/dockerui     "/dockerui"            2 days ago          Up 6 hours          0.0.0.0:9000->9000/tcp   dockerui_qinwen         
e278cabec91e        centos                "/bin/bash"            2 days ago          Up 6 hours                                   centos_aways

在浏览器中输入：http://192.168.1.129:9999/，可以看到nginx的默认界面，配置成功
