如何通过 docker-php-ext-install 为 php 安装扩展？

Question

为了 解决问题，我现在尝试通过安装 mysql pdo

 docker-php-ext-install

正如 php 图像的自述文件中 所指出的那样。

然而我的电话失败了，说明：

 Libraries have been installed in:
   /usr/src/php/ext/mysqli/modules

If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
   - add LIBDIR to the `LD_LIBRARY_PATH' environment variable
     during execution
   - add LIBDIR to the `LD_RUN_PATH' environment variable
     during linking
   - use the `-Wl,--rpath -Wl,LIBDIR' linker flag
   - have your system administrator add LIBDIR to `/etc/ld.so.conf'

See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.
----------------------------------------------------------------------

Build complete.
Don't forget to run 'make test'.

Make sure that you run '/usr/local/bin/phpize' in the top level source directory of the module

ERROR: Service 'phlaconapp' failed to build: The command '/bin/sh -c docker-php-ext-install mysqli mysqlnd pdo pdo_mysql zip' returned a non-zero code: 1

这是我的 docker-compose.yml ：

 phlaconapp:
    hostname: phaclonapp
    dockerfile: Dockerfile
    build: ./
    ports:
        - "1080:80"
        - "1043:433"
    environment:
        TERM: xterm-color
        ENVIRONMENT: dev
    volumes:
        - ./:/var/www/html/
    links:
        - mysql
mysql:
    image: mysql:5.6
    volumes:
        - ./docker/mysql.d:/etc/mysql/conf.d
    ports: ["3306:3306"]
    environment:
        MYSQL_ROOT_PASSWORD: 'root'

这是我的 Dockerfile ：

 FROM php:5.6-apache

RUN php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');" && \
    php -r "if (hash_file('SHA384', 'composer-setup.php') === '070854512ef404f16bac87071a6db9fd9721da1684cd4589b1196c3faf71b9a2682e2311b36a5079825e155ac7ce150d') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;" && \
    php composer-setup.php && \
    php -r "unlink('composer-setup.php');"

RUN apt-get update && \
    apt-get install vim git -y
RUN docker-php-ext-install mysqli mysqlnd pdo pdo_mysql zip

RUN  cd /  && \
    git clone --depth=1 git://github.com/phalcon/cphalcon.git && \
    cd cphalcon/build && \
    ./install

RUN echo "extension=phalcon.so" > /usr/local/etc/php/conf.d/phalcon.ini
RUN a2enmod rewrite

并且运行 docker-compose build 不会完成。

将 memcached 安装到 Docker PHP 容器的 2019 年方式和可能的 2020 年方式是 https://hub.docker.com/_/php 上描述的方式

FROM php:latest
RUN pecl install memcached \
    && docker-php-ext-enable memcached

 FROM php:5.6-cli
RUN apt-get update && apt-get install -y libmemcached-dev zlib1g-dev \
    && pecl install memcached-2.2.0 \
    && docker-php-ext-enable memcached
