Dockerfile

# Multi-stage Dockerfile — 各 entry スクリプトを Docker 内でテストするための image
#
# ビルド:
#   docker build --target server  -t ubuntu-setup-test:server  .
#   docker build --target desktop -t ubuntu-setup-test:desktop .
#
# オプション:
#   --build-arg UBUNTU_VERSION=22.04   (default 24.04)
#   --build-arg TZ=Europe/London       (default Asia/Tokyo)
#
# テスト手順は doc/test_in_docker.md を参照

# 全 entry に共通の依存と sudo-user 作成、TZ・locale 固定
