Dockerと掛けまして、船着場のレンタル屋さんと解きます、
そのココロは・・・「コンテナかそうか」
IT謎かけ勉強中の、ユゲタです。
最近ローカル環境を全て、Docker環境に変更して、macのbrewすら使わなくなって1年ぐらい経ちますが、
なんか、以前作ったシステムの画像表示がうまくできなくて、なんでかな〜?と考えていた時に、
dockerで立ち上げているphpにGDライブラリがインストールされていないと言うことに、今頃になって気がつきました。
DockerのイメージでPHPを最新のバージョン8にして喜んでいたのも束の間、GDライブラリってそのPHPイメージには同梱されていない上、イメージがalphineという軽量化されたイメージなので、
apt-getも使えないときた・・・なんか背水の陣なのかと考えたけど、
結果的に、webpライブラリも一緒にインストールすることができるようになったので、そのやり方を備忘録として、記述しておきます。
docker-compose環境
version: '3'
services:
php:
container_name : php
build : ./php
volumes:
- %webサイトのドキュメントroot相対パス%:/var/www/html
working_dir: /var/www/html
nginx:
container_name: nginx
image: nginx:1.19.5-alpine
ports:
- 8888:80
volumes:
- ./nginx/default.conf:/etc/nginx/conf.d/default.conf
- %webサイトのドキュメントroot相対パス%:/var/www/html
depends_on:
- php
【注意】%webサイトのドキュメントroot相対パス%には、自分の環境の開発フォルダのroot階層を相対パスで記述してください。
server {
listen 80;
server_name localhost;
index index.php index.html;

location ~ \.php$ {

fastcgi_pass php:9000;
fastcgi_index index.php;
include fastcgi_params;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
fastcgi_param PATH_INFO $fastcgi_path_info;
}
}
FROM php:8.1-fpm-alpine
RUN apk update && \
# apk upgrade && \
apk add --update --no-cache \
# autoconf \
# zlib1g-dev \
libjpeg-turbo-dev \
libwebp-dev \
libpng-dev
# libxml2-dev \
# libxslt-dev
RUN docker-php-ext-configure gd --with-jpeg
# RUN docker-php-ext-configure gd
# RUN docker-php-ext-install gd
RUN docker-php-ext-install -j$(nproc) gd
# RUN apk add php8.1-gd
確認方法
dockerを立ち上げたら、環境構築のroot階層にinfo.phpを置いて、その中を見てみましょう。
ちなみに、dockerの立ち上げは、docker-compose.ymlが置かれた場所で次のコマンドを実行しましょう。(わからない人の為に書いておきます)
$ docker-compose up -d
info.phpの中身は次の通りです。
<?php phpinfo();
http://localhost:8888/info.php
のアドレスにアクセスすると、info画面が現れます。
重要なのはgdの箇所がちゃんと表示されていて、対象のモジュールがenableになっているかどうかです。
jpeg , png , gif, webpがそれぞれ、enableになっているのが確認できたら成功です。
無事にphpでgd操作ができるようになって、画像のバイナリが扱えるようになります。
ワンステップアップの余談
info.phpをいちいち設置するのが、面倒くさい、手間がかかる、時間がない、やってらんない、という人のために、コマンドでサクっと確認できる方法を最後に記述しておきます。
まずdocker-composeでコンテナを立ち上げた後で、次のコマンドでコンテナ内に入ります。
$docker exec -it php ash
次に、phpinfoを表示するには、次のコマンドです。
$php -r 'phpinfo();'
結果は次のような感じです。※まあまあ長いです。

/var/www/html # php -i 'phpinfo();' | grep gd
