alpine linux + Rails(Puma) 起動エラーで悩みまくった話
前書き
世間ではコンテナ技術が一般的になりますが、任せちゃうがゆえに低レイヤーの知識がなくても使えてしまいますね。
そしてコンテナを作ろうとした際にはまる。私もそんな一人です。対応としては動かしてみてエラーをつぶすしかないでしょうね。
いろいろはまり、検索してもあまりヒットしなかったので忘備録として残します。
まとめとしては、 alpine の パッケージ検索して、alpine のバージョンを確認しようでした
発生した問題
上記の時、以下のエラーが出ました。

TRY & ERROR
- openssl-dev を入れてみよう
- ssl 系なので行けると思ったのですが、コンフリクト[1]が発生して build が失敗
- libressl-dev を入れてみよう
- 1 で記載されているが、alpine では openssl は使われていないらしい、エラーが変わらず
- エラーに従って libssl1.1 を入れてみよう
- build で失敗。 libssl1.0 は入れれたけどエラーは変わらない
最終的な解決方法
パッケージ調べたら alpine 3.9[2] 以降でないとダメそうでした。
仕方がないので、公開されている記事[3]を参考に独自にRuby を入れることにしました。
