摘要：一測試在官方的基礎上簡化基礎鏡像阿里源維護者信息添加擴展這里目標，這里是在運行上面鏡像的容器測試得到結果，部分需要自行下載的插件或交互式安裝的，使用多帶帶下載源碼編譯的方式。

一、測試PHP
1、在官方的基礎上簡化：

# php7.3.5; Feb 7, 2019 link: https://github.com/docker-library/php/blob/master/7.3/alpine3.9/fpm/Dockerfile
# Base images 基礎鏡像+阿里源

    && apk update 
    && addgroup -g 82 -S www-data

RUN set -eux; 
        apk add $PHPIZE_DEPS $PHPIZE_DEVS 
            
        # && wget -O php.tar.xz "$PHP_URL" 
        && tar -Jxf php.tar.xz && cd php-$PHP_VERSION && ./configure 
        --prefix="/usr/local/php" 
        --with-config-file-path="/usr/local/php/etc" 
        --with-config-file-scan-dir="/usr/local/php/etc/conf.d" 
        
        --enable-option-checking=fatal 
        --with-mhash

    && make -j "$(nproc)" 
    && find -type f -name "*.a" -delete 
    && make install 
#    && make clean 
    && rm -rf /tmp/pear ~/.pearrc 
    && cd ../ && rm -rf php-$PHP_VERSION.tar.xz php-$PHP_VERSION

2、添加擴展：
這里目標 swoole-inotify-redis-uuid-memcached，這里是在運行上面鏡像的容器測試得到結果，部分需要自行下載的插件或交互式安裝的，使用多帶帶下載源碼編譯的方式。/usr/local/php/etc/文件夾需要準備一個共享，這里取上面官方的配置稍加修改，并共享出來供后續安裝使用：

[]:~/tmp/dk# tree -a php
php
├── config
│?? ├── pear.conf
│?? ├── php-fpm.conf
│?? ├── php-fpm.conf.default
│?? ├── php-fpm.d
│?? │?? ├── www.conf
│?? │?? └── www.conf.default
│?? ├── php.ini
│?? └── start.sh
├── Dockerfile
└── php.tar.xz 

測試shell到Dockerfile的代碼。其中在安裝memcached(相當于是memcache的新版、強化版)時遇到問題，官方memcached很快安裝成功但php擴展難裝：多次出現編譯錯誤，php的memcached報缺libmemcached，而后者總是無法通過
參考《錯誤解決》，使用其中的參考自:https://bugs.launchpad.net/li...

Bug Description
When building with latest GCC version 7
----------

clients/memflush.cc:42:22: error: ISO C++ forbids comparison between pointer and integer [-fpermissive]
   if (opt_servers == false)
                      ^~~~~
clients/memflush.cc:51:24: error: ISO C++ forbids comparison between pointer and integer [-fpermissive]
     if (opt_servers == false)
                        ^~~~~

Trivial fix:
http://pkgs.fedoraproject.org/cgit/rpms/libmemcached.git/plain/libmemcached-build.patch
#打補丁，興奮半天沒有效果
http://pkgs.fedoraproject.org/cgit/rpms/libmemcached.git/plain/libmemcached-build.patch
patch -p0 < libmemcached-build.patch

最終使用 apk add libmemcached-dev 安裝成功！！！（apk add libmemcached，或search的各版本都不行，只要一個dev）

#測試

#swoole 需要對話參數，所以自定義安裝
RUN set -ex && 
    mkdir -p ~/build/swoole && 
    cd ~/build/swoole &&

#memcached
RUN set -ex && 
    #測試命令：/usr/bin/memcached -d -m 1024 -u root -l 0.0.0.0 -p 11211 -c 1024 -P /tmp/memcached.pid 啟動正常
    mkdir -p ~/build/memcached &&

    make && make install && 
    cd ../ && rm -rf memcached* && 
    
    #需要libmemcached
    apk add libmemcached-dev && 
    
    mkdir -p ~/build/memcached_p && 
    cd ~/build/memcached_p && 
    wget -O memcached.tgz "https://pecl.php.net/get/memcached-3.1.3.tgz" && 
    tar -zxf memcached.tgz --strip-components 1 && 
    /usr/local/php/bin/phpize && 
    ./configure --with-php-config=/usr/local/php/bin/php-config && 
    make && make install && 
    cd ../ && rm -rf memcached_p*

#編譯使用，運行時共享 -v /your_real_path/ /usr/local/php/etc/
COPY config /usr/local/php/etc
VOLUME ["/usr/local/php/etc","/var/www/html"]

RUN set -ex 
    && /usr/local/php/bin/pecl channel-update pecl.php.net 
    && /usr/local/php/bin/pecl install igbinary event 
    && /usr/local/php/bin/php -m

3、合并，再添加

CMD ["/usr/local/php/etc/start.sh"]
