Dockerfile

--with-jpeg-dir でJPEGも有効になる。

Dockerfile

FROM php:8.1.1-apache
COPY ./php.ini /usr/local/etc/php/
RUN apt-get update \
  && apt-get install -y libfreetype6-dev libjpeg62-turbo-dev libpng-dev \
  && docker-php-ext-configure gd --with-jpeg-dir=/usr \
  && docker-php-ext-install pdo_mysql mysqli mbstring gd iconv

php.ini

php.ini

[Date]
date.timezone = "Asia/Tokyo"
[mbstring]
mbstring.internal_encoding = "UTF-8"
mbstring.language = "Japanese"
