Docker の php:apache に、Composer を使えるようにする Dockerfile を作る

スポンサードリンク


まとめ。Composer が使える Docker の php:apache の Dockerfile

From php:apache
RUN apt-get update && apt-get install -y \
    unzip \
    zlib1g-dev \
    && docker-php-ext-install \
    zip \
    && apt-get clean \
    && rm -rf /var/lib/apt/lists/*
RUN curl -s http://getcomposer.org/installer | php && \
    mv composer.phar /usr/local/bin/composer

これが最低限必要なものを追加した Dockerfile と思いますが、ちょっと及び腰で念の為という気持ちで、利便性や、参考ページにあったものも一応追加したものが次となります。

  • git はインストールしなくても使えるが入れた。
  • echo "export PATH=${PATH}:/var/www/vendor/bin" >> ~/.bashrc && \ も無くてもよいと思う (未検証) が、一応入れた。
From php:apache
RUN apt-get update && apt-get install -y \
    git \
    unzip \
    zlib1g-dev \
    && docker-php-ext-install \
    zip \
    && apt-get clean \
    && rm -rf /var/lib/apt/lists/*
RUN curl -s http://getcomposer.org/installer | php && \
    echo "export PATH=${PATH}:/var/www/vendor/bin" >> ~/.bashrc && \
    mv composer.phar /usr/local/bin/composer

はじめるにあたって

次をベースにしました。

の次の部分です。

試行錯誤 1. crypt の有効に失敗する

From php:apache
RUN curl -s http://getcomposer.org/installer | php && \
    echo "export PATH=${PATH}:/var/www/vendor/bin" >> ~/.bashrc && \
    mv composer.phar /usr/local/bin/composer

bash で入ったあと、composer を使ってみますと、次のようにエラーとなりました><。

$ docker container run --rm -it pc:1 bash

root@d8b4bc873df6:/var/www/html#    

crypto が入っていないからでしょうか。PHP 拡張の mcrypt を入れれば良いでしょうか。。。

と思ったらダメなようです。PHP 7.2 から削除されています。

となると、php-openssl ですが、これは最初から入っています。ですので、OpenSSL を入れれば良いでしょうか。

From php:apache
RUN apt-get update && apt-get install -y \
    openssl \
    && apt-get clean \
    && rm -rf /var/lib/apt/lists/*

RUN curl -s http://getcomposer.org/installer | php && \
    echo "export PATH=${PATH}:/var/www/vendor/bin" >> ~/.bashrc && \
    mv composer.phar /usr/local/bin/composer

これでビルドしてみましたけれども、OpenSSL はすでに入っているようなのですよね。。。

$ docker build -t pc:1 .
Sending build context to Docker daemon  2.048kB
... 略 ...
penssl is already the newest version (1.1.0f-3+deb9u2).
openssl set to manually installed.
0 upgraded, 0 newly installed, 0 to remove and 1 not upgraded.
Removing intermediate container 1452c3998c7b
 ---> aae4dbeccf2c
... 略 ...

気になって、最初の Dockerfile でコンテナ、イメージ、全て削除してからビルドしてやり直して、Composer を動かしてみましたら、再現しませんでした。

よって、apt-get openssl は不要でしょう♪

試行錯誤 2. php-zip が無い

ではうまく行ったかと申しますと、ダメでした><。

PHP 拡張の ZIP が無い、とのことです。

$ docker container run --rm -it pc:1 bash
root@e91bb8cebba4:/var/www/html# composer global require "laravel/installer"
Changed current directory to /root/.composer
Do not run Composer as root/super user! See https://getcomposer.org/root for details
Using version ^2.0 for laravel/installer
./composer.json has been created
Loading composer repositories with package information
Updating dependencies (including require-dev)
Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - laravel/installer v2.0.1 requires ext-zip * -> the requested PHP extension zip is missing from your system.
    - laravel/installer v2.0.0 requires ext-zip * -> the requested PHP extension zip is missing from your system.
    - Installation request for laravel/installer ^2.0 -> satisfiable by laravel/installer[v2.0.0, v2.0.1].

  To enable extensions, verify that they are enabled in your .ini files:
    - 
    - /usr/local/etc/php/conf.d/docker-php-ext-sodium.ini
  You can also run `php --ini` inside terminal to see which files are used by PHP in CLI mode.

Installation failed, deleting ./composer.json.
root@e91bb8cebba4:/var/www/html# 

システムに ZIP があるか、PHP の ZIP はあるか、調べました。

どちらも、ありませんでした。

$ docker container run --rm -it pc:1 bash
root@54939e75627f:/var/www/html# dpkg -l zip
dpkg-query: no packages found matching zip
root@54939e75627f:/var/www/html# php -m | grep zip
root@54939e75627f:/var/www/html# 

まずは、PHP 拡張の ZIP のみ入れてみます。

From php:apache
RUN docker-php-ext-install \
    zip
RUN curl -s http://getcomposer.org/installer | php && \
    echo "export PATH=${PATH}:/var/www/vendor/bin" >> ~/.bashrc && \
    mv composer.phar /usr/local/bin/composer
$ docker image build --no-cache=true -t pc:1 .
Sending build context to Docker daemon  14.85kB
... 略 ...
checking libzip... no
checking for the location of zlib... configure: error: zip support requires ZLIB. Use --with-zlib-dir=<DIR> to specify prefix where ZLIB include and library are located
The command '/bin/sh -c docker-php-ext-install     zip' returned a non-zero code: 1

ダメでした。ZLIB が足りないようです。

を見て、次のようにしました。

From php:apache
RUN apt-get update && apt-get install -y \
    zlib1g-dev \
    && docker-php-ext-install \
    zip \
    && apt-get clean \
    && rm -rf /var/lib/apt/lists/*
RUN curl -s http://getcomposer.org/installer | php && \
    echo "export PATH=${PATH}:/var/www/vendor/bin" >> ~/.bashrc && \
    mv composer.phar /usr/local/bin/composer

これで、ビルドしたところ、うまくいきました。確かめてみます。

$ docker container run --rm -it pc:1 bash
root@d8654ce3554b:/var/www/html# dpkg -l zip
dpkg-query: no packages found matching zip
root@d8654ce3554b:/var/www/html#

+++-=====================================-=======================-=======================-===============================================================================
ii  zlib1g-dev:amd64                      1:1.2.8.dfsg-5          amd64                   compression library - development
root@d8654ce3554b:/var/www/html# php -m | grep zip
zip
root@d8654ce3554b:/var/www/html# 

そもそも、dpkg -l zip ではシステムに ZIP が入っているかどうかはわからないのですね。ですので、今回インストールした zlib1g-dev で確認しました。PHP には、zip が入っています。

また、zip コマンドを試してみたところ、これは入っていませんでした。システムには zip は入っていませんけれども、PHP 拡張としては入ったことになります。

さて、もう一度 Composer を試してみましょう。

$ docker container run --rm -it pc:1 bash
root@841b3d1a7cc9:/var/www/html# composer global require "laravel/installer"

無事、Laravel のインストーラーがインストールできました!やったぜ!

試行錯誤 3. Laravel プロジェクトを作ってみる。

続いて、Laravel プロジェクトを作ってみます。

root@841b3d1a7cc9:/var/www/html# laravel new blog
bash: laravel: command not found
root@841b3d1a7cc9:/var/www/html# 

ダメです。

を見ると、laravle コマンドが使えるように、$PATH を通してやれば良いようです。インストーラーのインストール時に、

Changed current directory to /root/.composer

とありましたのでここらへんを探せばよいのでしょう。

root@841b3d1a7cc9:/var/www/html# ls -al ~/.composer/vendor/bin
total 8
drwxr-xr-x 2 root root 4096 Oct 10 22:55 .
drwxr-xr-x 8 root root 4096 Oct 10 22:55 ..
lrwxrwxrwx 1 root root   28 Oct 10 22:55 laravel -> ../laravel/installer/laravel
root@841b3d1a7cc9:/var/www/html# 

ありました! 早速、$PTATH を通します。

次も参考になりました!

root@841b3d1a7cc9:/var/www/html# echo "export PATH=${PATH}:~/.composer/vendor/bin"  >> ~/.bashrc
root@841b3d1a7cc9:/var/www/html# source ~/.bashrc

/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/var/www/vendor/bin:/root/.composer/vendor/bin
root@841b3d1a7cc9:/var/www/html# 

これで、larabel new コマンドが、次のように使えるようになりました!

As there is no ‘unzip’ command installed zip files are being unpacked using the PHP zip extension.
This may cause invalid reports of corrupted archives. Installing ‘unzip’ may remediate them.

とあります。また ZIP です。

試行錯誤 4. unzip と git をインストールする。

試しにapt-get install unzip でインストールしてから、もう一度やってみました。今度は laravel new blog2

すると、エラーが消えました♪

の System Requirements を見ると、次のようあります。

To install packages from sources instead of simple zip archives, you will need git, svn, fossil or hg depending on how the package is version-controlled.

ということは、もしかして unzip で無くても git があれば、git を使っているパッケージであればよいのでしょう。

試してみましょう。 apt remove unzip 後、apt-get install git しました。

そして laravel new blog4 などとしてみると、、、

As there is no ‘unzip’ command installed zip files are being unpacked using the PHP zip extension.

は出ました。

ということは、 unzip は composer に必須 、という理解で良さそうです。

そして、もしかしたら必須ではないのかもしれませんが、ドキュメントにも必要になるだろうとありますし、git は加えておこうと思います。

From php:apache
RUN apt-get update && apt-get install -y \
    git \
    unzip \
    zlib1g-dev \
    && docker-php-ext-install \
    zip \
    && apt-get clean \
    && rm -rf /var/lib/apt/lists/*
RUN curl -s http://getcomposer.org/installer | php && \
    echo "export PATH=${PATH}:/var/www/vendor/bin" >> ~/.bashrc && \
    mv composer.phar /usr/local/bin/composer

次のコマンドで、ビルドし、コンテナに入って確かめてみます。

docker image build --no-cache=true -t pc:1 .
docker container run -it --rm pc:1 bash

今度は、composer create-project --prefer-dist laravel/laravel blog コマンドで Laravel インストールをしてみます。

うまくいきました。

これでおしまいです。

おわりに

PHP の環境を整えて、Larvel を自由に使いたいのですけれども、Composer 一つとっても考えるべきことが多いです。

一つづつ理解していこうと思います。

以上です。
