docker使用alpine镜像
alpine介绍
alpine简要介绍
Alpine 的意思是“高山的”，比如 Alpine plants高山植物，Alpine skiing高山滑雪、the alpine resort阿尔卑斯山胜地。
alpine系统特点
小巧：基于Musl libc和busybox，和busybox一样小巧，最小的Docker镜像只有5MB；
安全：面向安全的轻量发行版；
简单：提供APK包管理工具，软件的搜索、安装、删除、升级都非常方便。
适合容器使用：由于小巧、功能完备，非常适合作为容器的基础镜像。
alpine镜像的使用
官方 Alpine 镜像的文档：http://gliderlabs.viewdocs.io/docker-alpine/
docker pull alpine
docker run -it --name myalpine alpine:v1
下载镜像
1.在线在docker官方仓库下载 仓库在国外，不好拉取镜像
#查看官方alpine镜像
docker search alpine
#拉取镜像
docker image pull itsthenetework/nfs-server-alpine
# 导入nginx镜像(推荐使用)
docker load -i docker_nginx.tar.gz
2.离线下载 alpine-3.10下载地址 alpine-3.11下载地址
# 导入nginx镜像(推荐使用)
docker load -i docker_nginx.tar.gz
更新镜像源
因为官方源在国外，我们改成国内的清华源
docker run -it -p 80:80 alpine:latest
/ # sed -i 's/dl-cdn.alpinelinux.org/mirrors.tuna.tsinghua.edu.cn/g' /etc/apk/repositories
/ # apk update
安装nginx
/ # apk add nginx
/ # mkdir /run/nginx
/ # nginx
注： 打开网页出现404原因 答：没有原因，默认配置文件默认写的就是显示404
return 404;
#替换
root /html;
index index.html;
提交成镜像
docker commit <alpineID> nginx_alpine:v1
docker run -d -p 81:80 nginx_alpine:v1 nginx -g 'daemon off;'
alpine安装kod
1. 启动alpine容器
docker run -it -p 80:80 alpine:v1
/ # sed -i 's/dl-cdn.alpinelinux.org/mirrors.tuna.tsinghua.edu.cn/g' /etc/apk/repositories
/ # apk update
/ # apk add nginx
/ # mkdir /run/nginx
/ # nginx
/ # apk add php7 php7-fpm php7-opcache php7-curl php7-gd php7-mbstring php7-mysqli php7-json php7-iconv php7-exif php7-ldap php7-pdo php7-session php7-xml
安装 rc-service
apk add openrc --no-cache
启动nginx
service nginx start
#或者rc-service nginx start
遇到问题
WARNING: nginx is already starting
/# service nginx status
* You are attempting to run an openrc service on a
* system which openrc did not boot.
* You may be inside a chroot or you may have used
* another initialization system to boot this system.
* In this situation, you will get unpredictable results!
* If you really want to do this, issue the following command:
* touch /run/openrc/softlevel
/# touch /run/openrc/softlevel
touch: /run/openrc/softlevel: No such file or directory
/# mkdir -p /run/openrc
/# touch /run/openrc/softlevel
/# service nginx status
* status: stopped
/# service nginx start
* WARNING: nginx is already starting
/# /sbin/openrc
* Caching service dependencies ... [ ok ]
/# rc-service nginx start
* /run/nginx: creating directory
* /run/nginx: correcting owner
* Starting nginx ... [ ok ]
启动php-fpm
vi /etc/php7/php-fpm.d/www.conf
所属主和所著组为nginx
/# service php-fpm7 start
* Checking /etc/php7/php-fpm.conf ...
* /run/php-fpm7: creating directory

加入启动服务
/# rc-update add nginx default
/# rc-update add php-fpm7 default
安装可道云
vim /etc/nginx/conf.d/default.conf
server {
listen 80 default_server;
listen [::]:80 default_server;
location / {
root /html;
index index.php index.html;
include /etc/nginx/conf.d./*.conf;
location ~ \.php$ {
root /html;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /html$fastcgi_script_name;
include fastcgi_params;
}
}
# You may need this to prevent return 404 recursion.
location = /404.html {
internal;
}
}
#检查格式
nginx -t
创建站点目录
mkdir /html
cd /html
wget http://static.kodcloud.com/update/download/kodexplorer4.40.zip
chown -R nginx:nginx .
#重启nginx
service nginx restart
service php-fpm7 restart
启动脚本文件
vim /init.sh
service nginx start
service nginx restart
service php-fpm7 start
service php-fpm7 restart
tail -f /etc/hosts
注： 使用脚本时，nginx和php-fpm7启动一次失败，所以在这里在重启一次
提交镜像
docker commit optimistic_hermann alpine_kod:v1
验证镜像
docker run -d -p 80:80 alpine_kod:v1 /bin/sh /init.sh
