我花了大概一周的時(shí)間進(jìn)行了各種踩坑及實(shí)驗(yàn)，最終得出了一份可以使用的dockerfile及compose

php7

mysql_pdo

postgre_pdo

phpredis

swoole(可選，如應(yīng)用swoole，dockerfile及nginx的配置會(huì)有所變化)

dockerfile分為兩部分，一部分為php服務(wù)，一部分為nginx(swoole下可選)

先貼代碼吧

### php7 ###

## swoole可以不依賴nginx 所以我多帶帶貼出php-fpm的nginx

nginx-dockerfile:

from nginx:1.13.6-alpine
ENV TIME_ZONE Asiz/Shanghai
RUN sed -i "s/dl-cdn.alpinelinux.org/mirrors.ustc.edu.cn/g" /etc/apk/repositories && 
    apk update && 
    apk add --no-cache tzdata  &&  
   echo "${TIME_ZONE}" > /etc/timezone &&  
   ln -sf /usr/share/zoneinfo/${TIME_ZONE} /etc/localtime 
COPY default.conf /etc/nginx/conf.d
EXPOSE 80
STOPSIGNAL SIGTERM
CMD ["nginx", "-g", "daemon off;"]

nginx_php-fpm:default.conf:

server {
    listen       80;
    server_name  *.yourserver.com;
    location / {
          autoindex on; 
          if ($request_filename !~* /(index.php|assets|uploads|phpinfo.php)) 
            {   
               rewrite ^/(.*)$ /index.php/$1 last;                                                                                                 
            }                                                                                      
    }
    location ~ .php(/|$) {
        fastcgi_split_path_info ^(.+?.php)(/.*)$;
        fastcgi_pass php-fpm:9000;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME /www$fastcgi_script_name;
        fastcgi_param PATH_INFO $fastcgi_path_info;
        include fastcgi_params;
    } 
}

compose:

* swoole的編排模板很容易寫 我就不在這里貼出了

version: "2"
services:
  php-fpm:
    image: "php-fpm"
    restart: always
    #日志系統(tǒng)，可不寫
    #logging:
    #  driver: fluentd
    #  options:
    #    fluentd-address: "logaddr:24224"
    #    tag: "docker/{{.Name}}/{{.ID}}/{{.ImageName}}"
  php-nginx:
    image: "php-nginx"
    depends_on:
    #這幾個(gè)是轉(zhuǎn)義字符 但是不知道為什么就顯示出來(lái)了，使用的時(shí)候自己去掉一下
      - php-fpm
    ports:
      - "80:80"
    links:
      - php-fpm
    restart: always
    #日志系統(tǒng)，可不寫
    #logging:
    #  driver: fluentd
    #  options:
    #    fluentd-address: "logaddr:24224"
    #    tag: "docker/{{.Name}}/{{.ID}}/{{.ImageName}}"
    

我所做的是對(duì)php及nginx進(jìn)行解耦
如果集群內(nèi)有多個(gè)php服務(wù)需要互相訪問(wèn)，
因?yàn)閏ompose不允許兩個(gè)服務(wù)互相l(xiāng)ink
所以需要?jiǎng)?chuàng)建一個(gè)network在network中借助nginx進(jìn)行互相訪問(wèn)
但是目前只有v3版的compose支持本功能，很多舊集群都無(wú)法正常支持本功能，所以我就不貼出代碼了
編輯完成后，即可通過(guò)80端口訪問(wèn)index.php了
