第7章 Docker手动制作镜像
1.手动制作游戏镜像
下面我们基于centos容器制作一个新镜像，并安装nginx服务
1.1 启动一个容器并安装nginx
[root@docker-11 ~]# docker run -it centos /bin/bash
[root@0ede2760ba65 /]# yum install wget install openssh-clients -y
[root@0ede2760ba65 /]# wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
[root@0ede2760ba65 /]# wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-7.repo
[root@0ede2760ba65 /]# sed -i -e '/mirrors.cloud.aliyuncs.com/d' -e '/mirrors.aliyuncs.com/d' /etc/yum.repos.d/CentOS-Base.repo
[root@0ede2760ba65 /]# cat /etc/yum.repos.d/nginx.repo
[nginx-stable]
name=nginx stable repo
baseurl=http://nginx.org/packages/centos/$releasever/$basearch/
gpgcheck=1
enabled=1
gpgkey=https://nginx.org/keys/nginx_signing.key
[nginx-mainline]
name=nginx mainline repo
baseurl=http://nginx.org/packages/mainline/centos/$releasever/$basearch/
gpgcheck=1
enabled=0
gpgkey=https://nginx.org/keys/nginx_signing.key
[root@0ede2760ba65 /]# yum makecache fast
[root@0ede2760ba65 /]# yum install nginx -y
1.2 上传代码目录并配置nginx配置文件
[root@0ede2760ba65 /]# scp -r 10.0.0.11:/data/* /opt/
[root@0ede2760ba65 /]# ll /opt/
total 18896
drwxr-xr-x 5 root root 73 Sep 7 16:02 game
-rw-r--r-- 1 root root 303 Sep 7 16:02 game.conf
-rw-r--r-- 1 root root 19248295 Sep 7 16:02 html5.zip
drwxr-xr-x 3 root root 92 Sep 7 16:02 xiaoniao
-rw-r--r-- 1 root root 91014 Sep 7 16:02 xiaoniaofeifei.zip
[root@0ede2760ba65 /]# cp /opt/game.conf /etc/nginx/conf.d/
1.3 将容器提交为新的镜像
[root@docker-11 ~]# docker ps -aq
0ede2760ba65
[root@docker-11 ~]# docker commit 0ede2760ba65 game:v1
sha256:a61d28fbfe27ebe36d4b73825b55e5f94097083273ab56dccce0453ce2bd6d38
1.4 测试镜像功能是否可用
[root@docker-11 ~]# docker run -d -p 8080:8080 -p 8090:8090 game:v1 nginx -g 'daemon off;'
f58f209d4761c4bdd9bb164c0050a94a3273b1ee0e57eafe29e48b1517c72950
1.5 将新镜像导出
docker save -o game_v1.tar game:v1
2.手动制作云盘镜像
2.1 创建容器
docker run -d -p 80:80 --name clould game:v1 nginx -g 'daemon off;'
2.2 进入容器安装php并求改运行用户
[root@d0c987bcefa2 /]# yum install php-fpm -y
[root@d0c987bcefa2 /]# php-fpm -v

[root@d0c987bcefa2 /]# sed -i '/^user/c user = nginx' /etc/php-fpm.d/www.conf
[root@d0c987bcefa2 /]# sed -i '/^group/c group = nginx' /etc/php-fpm.d/www.conf
[root@d0c987bcefa2 /]# sed -i '/daemonize/s#no#yes#g' /etc/php-fpm.conf
[root@d0c987bcefa2 /]# php-fpm -c /etc/php.ini -y /etc/php-fpm.conf
[root@d0c987bcefa2 /]# php-fpm -c /etc/php.ini -y /etc/php-fpm.conf
[root@d0c987bcefa2 /]# ps -ef|grep php
root 77 0 0 21:43 ? 00:00:00 php-fpm: master process (/etc/php-fpm.conf)
nginx 78 77 0 21:43 ? 00:00:00 php-fpm: pool www
nginx 79 77 0 21:43 ? 00:00:00 php-fpm: pool www
nginx 80 77 0 21:43 ? 00:00:00 php-fpm: pool www
nginx 81 77 0 21:43 ? 00:00:00 php-fpm: pool www
nginx 82 77 0 21:43 ? 00:00:00 php-fpm: pool www
2.3 配置nginx
[root@d0c987bcefa2 /]# cat /etc/nginx/conf.d/cloud.conf
server {
listen 80;
server_name localhost;
root /code;
index index.php index.html;
location ~ \.php$ {
root /code;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;
}
}
[root@d0c987bcefa2 /]# nginx -t
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful
[root@d0c987bcefa2 /]# nginx -s reload
2.4 下载代码目录
[root@d0c987bcefa2 /]# mkdir /code
[root@d0c987bcefa2 /]# cd /code/
[root@d0c987bcefa2 code]# scp -r 10.0.0.11:/data/kod/* /code/
[root@d0c987bcefa2 code]# ls
ChangeLog.md README.MD app config data index.php plugins static
[root@d0c987bcefa2 code]# chown -R nginx:nginx /code/
2.5 测试
[root@d0c987bcefa2 code]# curl -I 127.0.0.1

2.6 提交新的镜像
[root@docker-11 ~]# docker commit d0c987bcefa2 kod:v1
sha256:169df6e8db11bd044e3e05237f2947783f9cc7a65b643dc9206ecf05fdc4a3ea
2.7 编写启动脚本并提交新镜像
[root@docker-11 ~]# docker exec -it c14835183fb5 /bin/bash
[root@c14835183fb5 /]# cat init.sh
#!/bin/bash
php-fpm -c /etc/php.ini -y /etc/php-fpm.conf
nginx -g 'daemon off;'
[root@c14835183fb5 /]# chmod +x init.sh
[root@docker-11 ~]# docker commit c14835183fb5 kod:v2
sha256:c05ebdf400aa7f7a27aa857df0d9c75c42943db89abca66f79101771db8e9585
2.8 启动测试
[root@docker-11 ~]# docker stop $(docker ps -qa)
[root@docker-11 ~]# docker run -d -p 80:80 kod:v2 /bin/bash /init.sh
dccf4aea5471713872e4fefaca45f7fac3bffec8f5f602570863ed14231dea1a
[root@docker-11 ~]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
dccf4aea5471 kod:v2 "/bin/bash /init.sh" 36 seconds ago Up 35 seconds 0.0.0.0:80->80/tcp magical_napier
2.9 添加GD库
此时打开页面提示缺少GD库，进入容器内安装php支持插件
[root@dccf4aea5471 /]yum install php-mbstring php-gd -y
然后重启容器
[root@docker-11 ~]# docker restart dccf4aea5471
2.10 访问测试没问题后提交新镜像
[root@docker-11 ~]# docker commit dccf4aea5471 kod:v2
sha256:23051ce545a2eb6bb50bb2307bd9cfbaf6139e52f205a4126fb1d8d974c417f4
