构建按需开启扩展的php Docker 镜像

项目中需要使用到mssql，因此php需要开启sqlsrv,pdo_sqlsrv的扩展，并且需要安装ODBC驱动。搜索了一圈，整理出成功方案如下：

# PHP 容器配置
FROM suyar/php:8.2-integration

# 构建生产/开发测试环境的镜像
ARG ENVIRONMENT

# 替换系统镜像源,修改composer镜像源
RUN sed -i 's@/deb.debian.org/@/mirrors.tuna.tsinghua.edu.cn/@g' /etc/apt/sources.list.d/debian.sources && composer config -g repo.packagist composer https://mirrors.aliyun.com/composer/

# 复制php配置文件
RUN  if [ "$ENVIRONMENT" = "development" ] ; then \ 
          mv "$PHP_INI_DIR/php.ini-development" "$PHP_INI_DIR/php.ini" ; \
     else \
          mv "$PHP_INI_DIR/php.ini-production" "$PHP_INI_DIR/php.ini" ; \
     fi

# 安装mssql驱动，procps
RUN curl https://packages.microsoft.com/keys/microsoft.asc | tee /etc/apt/trusted.gpg.d/microsoft.asc
RUN curl https://packages.microsoft.com/config/debian/12/prod.list | tee /etc/apt/sources.list.d/mssql-release.list
RUN sed -i 's/ signed-by=\/usr\/share\/keyrings\/microsoft-prod.gpg//g' /etc/apt/sources.list.d/mssql-release.list
RUN apt-get update && ACCEPT_EULA=Y apt-get install -y msodbcsql18 procps && apt-get upgrade -y && rm -rf /var/lib/apt/lists/*

# 增加 odbc, pdo_odbc 扩展 
RUN set -ex; \
docker-php-source extract; \
{ \
     echo '# https://github.com/docker-library/php/issues/103#issuecomment-271413933'; \
     echo 'AC_DEFUN([PHP_ALWAYS_SHARED],[])dnl'; \
     echo; \
     cat /usr/src/php/ext/odbc/config.m4; \
} > temp.m4; \
mv temp.m4 /usr/src/php/ext/odbc/config.m4; \
apt-get update; \
apt-get install -y --no-install-recommends unixodbc-dev; \
rm -rf /var/lib/apt/lists/*; \
docker-php-ext-configure odbc --with-unixODBC=shared,/usr; \
docker-php-ext-configure pdo_odbc --with-pdo-odbc=unixODBC,/usr; \
docker-php-ext-install odbc pdo_odbc; \
docker-php-source delete

RUN  if [ "$ENVIRONMENT" = "development" ] ; then\ 
          # 增加 sqlsrv, pdo_sqlsrv, xdebug 扩展  -- 用于开发,测试环境
          pecl channel-update pecl.php.net && pecl install sqlsrv pdo_sqlsrv xdebug && docker-php-ext-enable sqlsrv pdo_sqlsrv xdebug ; \
     else \
          # 增加 sqlsrv, pdo_sqlsrv 扩展 -- 用于生产环境
          pecl channel-update pecl.php.net && pecl install sqlsrv pdo_sqlsrv && docker-php-ext-enable sqlsrv pdo_sqlsrv ; \
     fi


# build 命令
# docker buildx build php:0.0.1 --build-arg="ENVIRONMENT=development" .
