GD を使える php:5.6-apache の Dockerfile 内容
FROM php:5.6-apache
RUN apt-get update && apt-get install -y \
libfreetype6-dev \
libjpeg62-turbo-dev \
libpng-dev \
&& docker-php-ext-install gd pdo_mysql mysqli mbstring \
&& apt-get clean \
&& rm -rf /var/lib/apt/lists/* \
&& a2enmod rewrite
COPY ./php.ini /usr/local/etc/php/
COPY ./000-default.conf /etc/apache2/sites-available/000-default.conf
ポイント
- docker-php-ext-install gd と GD を指定するだけではダメ、不足している。
- libfreetype6-dev, libjpeg62-turbo-dev, libpng-dev を事前に apt-get install する必要がある。
以上を行わず、単に docker-php-ext-install gd とした場合、docker build 時に次のようなエラーとなりました。

おまけ
Debian の Docker イメージ debian:9.5 （本投稿時の最新版） で PHP をインストール後、php-gd をインストールしようとすると、次のようになりました。
Dockerfile に指定したそれぞれのパッケージ
- libfreetype6-dev
- libjpeg62-turbo-dev
- libpng-dev
上記そのものはインストールされませんが、上記のものはすべて dev なので、おそらく上記のものは全て含んだパッケージなのでしょう。

おわりに
もともと、PHP GD の PHP: getimagesize – Manual が使用したかったのです。
ところが、Docker の php:5.6-apache には入っておりませんでした。
簡単にはインストール出来ませんでしたので、今回の投稿となりました。
次のページが参考になりました、ありがとうございます！
この公式ページで、GD のインストール方法が案内されておりましたので、解決がとても早かったです♪
以上です。
