docker imageのベースイメージをubuntu18.04に上げた時に
tzdata を apt-get install するところで止まってしまってハマったのでメモしておく
素のubuntu17.10の場合

実はこれも素の状態だとそのままinstallされる

Configuring tzdata
------------------
Please select the geographic area in which you live. Subsequent configuration
questions will narrow this down by presenting a list of cities, representing
the time zones in which they are located.
1. Africa 4. Australia 7. Atlantic 10. Pacific 13. Etc
2. America 5. Arctic 8. Europe 11. SystemV

↑ここで止まる
- timezoneの選択で止まってしまう
- ベースイメージを18.04変えたらtimezoneの選択で止まるようになった
- 17.10の時はdefaultでinstallされていた
- 素の18.04にtzdataをinstallする場合は止まらない
この状況から推測するに…
素の18.04に何か特定のpackageを追加すると止まるようになるのではないか
元々、ベースイメージに色々追加でパッケージを入れていたので、1個ずつ確認したところ…
gitが原因だった
FROM ubuntu:18.04
RUN apt-get update \
&& apt-get install -y \
git
RUN apt-get update \
