尝试为Docker官方镜像中的php-gd添加freetype

Question

我正在尝试添加一些功能的PHP GD安装。我使用Docker PHP“官方”版本作为基础(php:7.1.15-fpm-jessie)。

我当前的生产环境使用CentOS，它的GD模块支持FreeType、JPEG和PNG，您可以在phpinfo输出中看到：

GD Support => enabled
GD headers Version => 2.2.5
GD library Version => 2.2.5
FreeType Support => enabled
FreeType Linkage => with freetype
FreeType Version => 2.4.11
GIF Read Support => enabled
GIF Create Support => enabled
JPEG Support => enabled
libJPEG Version => 6b
PNG Support => enabled
libPNG Version => 1.5.13
WBMP Support => enabled
XPM Support => enabled
libXpm Version => 30411
XBM Support => enabled
WebP Support => enabled

Directive => Local Value => Master Value
gd.jpeg_ignore_warning => 1 => 1

但是这个Docker镜像没有FreeType和JPEG的支持，并且有一个更老的GD版本(参见下面的phpinfo )：

GD Support => enabled
GD Version => bundled (2.1.0 compatible)
GIF Read Support => enabled
GIF Create Support => enabled
PNG Support => enabled
libPNG Version => 1.2.50
WBMP Support => enabled
XBM Support => enabled

Directive => Local Value => Master Value
gd.jpeg_ignore_warning => 1 => 1

我需要重新编译PHP，还是只需要重新编译扩展？图片中使用的是Debian Jessie。

版本(解决方案)：

重新编译后，我在这篇文章中找到了最好的解决方案：

solved! Troubles with Docker + PHP7 + GD resulting in "Call to undefined function imagecreatefromjpeg()"

所以我简单地加了一句：

RUN apt-get update && apt-get install libgd3 libgd-dev && rm -rf /var/lib/apt/lists/*
RUN docker-php-ext-configure gd --with-freetype-dir=/usr/include/ --with-jpeg-dir=/usr/include/
RUN docker-php-ext-install -j$(nproc) gd

之后，我的phpinfo开始显示：

GD Support => enabled
GD Version => bundled (2.1.0 compatible)
FreeType Support => enabled
FreeType Linkage => with freetype
FreeType Version => 2.5.2
GIF Read Support => enabled
GIF Create Support => enabled
JPEG Support => enabled
libJPEG Version => 6b
PNG Support => enabled
libPNG Version => 1.2.50

Answer 1

将以下代码添加到您的Dockerfile：

RUN apt-get update && apt-get install -y libpng-dev 
RUN apt-get install -y \
    libwebp-dev \
    libjpeg62-turbo-dev \
    libpng-dev libxpm-dev \
    libfreetype6-dev

RUN docker-php-ext-configure gd \
    --with-gd \
    --with-webp-dir \
    --with-jpeg-dir \
    --with-png-dir \
    --with-zlib-dir \
    --with-xpm-dir \
    --with-freetype-dir \
    --enable-gd-native-ttf

RUN docker-php-ext-install gd

这对我很管用。

Answer 2

对于使用php7.3的我，删除--enable-gd-native-ttf

RUN apt-get update && apt-get install -y libpng-dev 
RUN apt-get install -y \
    libwebp-dev \
    libjpeg62-turbo-dev \
    libpng-dev libxpm-dev \
    libfreetype6-dev

RUN docker-php-ext-configure gd \
    --with-gd \
    --with-webp-dir \
    --with-jpeg-dir \
    --with-png-dir \
    --with-zlib-dir \
    --with-xpm-dir \
    --with-freetype-dir

RUN docker-php-ext-install gd

Answer 3

在寻找了很多方法来解决这个问题之后，我已经找到了这个设置，并且工作得很完美

FROM php:7.2-fpm
RUN apt-get update && apt-get install -y \
        libfreetype6-dev \
        libjpeg62-turbo-dev \
        libpng-dev \
    && docker-php-ext-install -j$(nproc) iconv \
    && docker-php-ext-configure gd --with-freetype-dir=/usr/include/ --with-jpeg-dir=/usr/include/ \
    && docker-php-ext-install -j$(nproc) gd
