I'm new to Docker and I'm trying to install PHP GD extension.
This is my current Dockerfile:
FROM php:7.4-fpm-alpine
RUN docker-php-ext-install mysqli pdo pdo_mysql bcmath gd
When running the docker via docker-compose build && docker-compose up -d I'm getting a lots of errors and in the end I get this message:
configure: error: Package requirements (zlib) were not met:
Package 'zlib', required by 'virtual:world', not found
Consider adjusting the PKG_CONFIG_PATH environment variable if you
installed software in a non-standard prefix.
Alternatively, you may set the environment variables ZLIB_CFLAGS
and ZLIB_LIBS to avoid the need to call pkg-config.
See the pkg-config man page for more details.
ERROR: Service 'php' failed to build: The command '/bin/sh -c docker-php-ext-install mysqli pdo pdo_mysql bcmath gd' returned a non-zero code: 1
Without the "gd" at the end the Docker container runs normally.
What could be the problem and how could I fix it?
You can add these settings in your Dockerfile:
FROM php:7.4-fpm
RUN apt-get update && apt-get install -y \
libfreetype6-dev \
libjpeg62-turbo-dev \
libpng-dev \
&& docker-php-ext-configure gd --with-freetype --with-jpeg \
&& docker-php-ext-install -j$(nproc) gd
