如何在 php:5.6-fpm-alpine docker 容器中啟用 Memcache

Question

這是php -m上的錯誤 output

警告：PHP 啟動：無法加載動態庫 '/usr/local/lib/php/extensions/no-debug-non-zts-20131226/memcache.so'

• 加載共享庫 /usr/local/lib/php/extensions/no-debug-non-zts-20131226/memcache.so 時出錯：第 0 行的 Unknown 中沒有此類文件或目錄

Dockerfile

ARG PHP_VERSION=5.6

FROM php:${PHP_VERSION}-fpm-alpine

RUN apk --update add openssh-client make grep autoconf gcc libc-dev zlib-dev

RUN cd /tmp \
    && curl -o php-memcache.tgz http://pecl.php.net/get/memcache-3.0.8.tgz \
    && tar -xzvf php-memcache.tgz \
    && cd memcache-3.0.8 \
    && curl -o memcache-faulty-inline.patch http://git.alpinelinux.org/cgit/aports/plain/main/php5-memcache/memcache-faulty-inline.patch?h=3.4-stable \
    && patch -p1 -i memcache-faulty-inline.patch \
    && phpize \
    && ./configure --prefix=/usr \
    && make INSTALL_ROOT=/ install \
    && install -d ./etc/php/conf.d \
    && echo "extension=memcache.so" > /usr/local/etc/php/conf.d/docker-php-ext-memcache.ini

docker-compose up -d 執行時沒有錯誤，擴展已啟用，但仍從系統中丟失。

注意：這是一個在 PHP 5.6 上運行的遺留系統，需要對它進行 docker 化，以便重構項目以在 PHP 7.x 上運行

項目依賴於Memcache而不是Memcached

問題是 docker Memcached容器，我嘗試使用 memcache 連接到 Memcached 服務器。

我找不到Memcache docker 容器，所以使用了Memcached 。
