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

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25

[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, ...

HTTP request sent, awaiting response... 200 OK Length: 895373 (874K) [application/octet-stream] Saving to: 'nginx-1.9.11.tar.gz' 100%[==========================================================================================================>] 895,373      357KB/s   in 2.5s    2016-02-24 06:14:46 (357 KB/s) - 'nginx-1.9.11.tar.gz' saved [895373/895373] [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：

1 2 3 4

[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）：

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21

[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 wanlong/my-nginx             v2                  b36ee38d811b        13 minutes ago      517.2 MB ubuntu                       latest              c29e52d44f69        6 days ago          187.9 MB wordpress                    latest              62a9acf5fc2a        12 days ago         517.3 MB nginx                        latest              bbb75b846e7b        12 days ago         134.5 MB dockerui/dockerui            latest              95c8b9dc91e0        3 weeks ago         6.13 MB redis                        latest              34ca6ac180ad        3 weeks ago         151.2 MB mongo                        latest              ad74160b3443        3 weeks ago         317.4 MB daocloud.io/library/python   latest              a2db1214d015        4 weeks ago         689.1 MB debian                       latest              5eb1402f0414        4 weeks ago         125.1 MB centos                       latest              60e65a8e4030        8 weeks ago         196.6 MB joedval/stress               latest              7eb627cb08a2        11 weeks ago        214.9 MB jpetazzo/nsenter             latest              10cbe4e038bc        5 months ago        368.3 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

1 2 3 4 5 6 7 8 9 10 11 12 13 14

[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
