コンテナ作成と実行。ここで、ホスト側で既にPostgreSQLが動いているので、ホスト側のポートを5431に設定している。

このあと/var/www/htmlに以下のような内容でphpinfo.phpファイルを作成。

<?php
    phpinfo();
?>

<?php

phpinfo();

ブラウザーからlocalhost:8080/phpinfo.phpにアクセスして以下のような内容を確認。

タイムゾーンはOSでAsia/Tokyoにしたが、PHPではUTCになっている
php.iniの場所が確認できる（/etc/php/8.1/apache2/php.ini）

DockerfileとComposeでインストール

手動でのインストールと同じ手順をDockerfileとComposeで管理する。

Dockerfileの内容は以下の通り。

aptでsystemctl, apache2, phpをインストール
apt-getでtzdataをインストール
/etc/timezoneに”Asia/Tokyo”を書き込む
dpkg-reconfigureでtzdataを再設定（noninteractiveで）

FROM ubuntu:latest

ENV DEBIAN_FRONTEND=noninteractive
ENV TZ Asia/Tokyo

RUN \
  apt update && \
  apt install -y systemctl && \
  apt install -y apache2 && \
  apt install -y php

RUN \
  apt-get update && \
  apt-get install -y tzdata

RUN \
  echo "${TZ}" > /etc/timezone && \
  dpkg-reconfigure -f noninteractive tzdata

CMD ["systemctl", "start", "apache2"]

FROM ubuntu:latest

ENV DEBIAN_FRONTEND=noninteractive

ENV TZ Asia/Tokyo

RUN \

apt update && \

apt install -y systemctl && \

apt install -y apache2 && \

apt install -y php

RUN \

apt-get update && \

apt-get install -y tzdata

RUN \

echo "${TZ}" > /etc/timezone && \

dpkg-reconfigure -f noninteractive tzdata

CMD ["systemctl", "start", "apache2"]

上記のDockerfileの内容でコンテナをビルド。

phpinfoのdateの項目中default timezoneがAsia/Tokyoになっているのが確認できる。

以下の内容でphp.iniをDokerfileと同じ場所に置き、DockerfileにADD ./php.ini /etc/php/8.1/apache2/php.iniを書くという方法も紹介されていたが、それがなくてもPHPのタイムゾーンは変更されていた。

ただしmbstringの方は今後設定が必要かもしれない。

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

[Date]

date.timezone = "Asia/Tokyo"

Docker – タイムゾーン

2023-11-16 / tau / コメントする

概要

Docker～UbuntuでタイムゾーンをUTC→JSTに変更した時の手順。

手動で設定

最初はUTC

タイムゾーンの設定なしにコンテナを起動するとUTCになっている。

# date
Wed Nov 15 12:38:34 UTC 2023

1 2	# date Wed Nov 15 12:38:34 UTC 2023

この時点で/etc/timezoneファイルは存在しない。
