はじめに

nablarch-example-batchは、nablarchフレームワークのバッチアプリケーション実装例である。

ただし、nablarch-example-batchはdocker用のexampleを提供していない。
このページでは、dockerコンテナでnablarch-example-batchを動かす方法を説明する。

結局、どうやったらできるのか

以下の通り。mvn packageコマンドはnablarch-example-batch手順に従って事前に実行する前提とする。

compose.yml

services:
  backend:
      build: .

Dockerfile

# syntax=docker.io/docker/dockerfile:1
FROM amazoncorretto:8-alpine3.19-jre

WORKDIR /opt/app

# zipの中には、jarファイル(実行ファイル)とlib(ライブラリ)が存在する。
COPY ./target/application-5u24.zip /opt/app/application.zip
# ヒアドキュメントの利用はsyntaxコメントが必要。DockerfileはLF改行必須。
RUN  <<EOF
  unzip /opt/app/application.zip
  chmod 777 /opt/app/nablarch-example-batch-5u24.jar
  chmod 777 -R /opt/app/lib
EOF

# h2の仕様では、相対パスのみが使用される場合現在の作業ディレクトリが開始点として使用されます。
# tomcatコンテナイメージでは、デフォルトの作業ディレクトリは/usr/local/tomcatです。
# env.properties で nablarch.db.url=jdbc:h2:./h2/db/rest_example を設定する場合、/usr/local/tomcat/h2/db/が正しい配置場所です。
COPY ./h2/db/nablarch_example.mv.db /opt/app/h2/db/

# fmtファイルとimputファイルを各ディレクトリに配置する。
COPY ./src/main/format/*.fmt /opt/app/src/main/format/
COPY ./work/input/*.csv /opt/app/work/input/

# この設定がないと、日本語のファイルを読み込めない場合がある。
ENV LANG=ja_JP.UTF-8

# exampleの手順とは、実行時引数の渡し方が違うので注意。
