1. APIを作ってデプロイしてみた 千歳ゆるい勉強会vol.2 2022.10.15 knot.
2. knot cistLT所属 最近dockerの勉強を始める 618knot 自己紹介
3. ゆるちとせvol.1の続きです
4. 大学HPから時刻表.pdfをとってくる 時刻表.pdfをcsvにする csvをjsonにして送る ←余計な処理だったね 大体こんな感じ
5. 使用技術(ざっくり) Python FastAPI Heroku
6. ネタバレ
7. いろいろぶっ壊れました (ため息)(どうして) ネタバレ
8. デモ動画 動画(こわれポイント①) 昨日(10/15)判明
9. これが本題ではなかった 8月時点ではちゃんと動いてた
10. デプロイ いっぱいファイルを作って Herokuにポイしてデプロイ
11. デプロイ後 デプロイ成功後しばらくは正常に動作 200 OK
12. デプロイ後 しばらくして、APIをたたいてみると(こわれポイント②) 500 Internal Server Error

15. エラーログをググる HerokuとかSeleniumまわりがダメそう ということはわかった どうしたらいいかわからん
16. 【悲報】Herokuの無料プラン終了のお知らせ →なおしても正直意味ない・モチベーション蒸発
17. そもそも もうちょっと簡単なAPIを作って練習した方がよかった？ いきなり複雑な処理はやめておくべきだったのでは...
18. これから まずはHerokuの代わりを探すところから？ render.comとかがいいらしいと聞く
19. APIを作ってデプロイしてみた (失敗) 千歳ゆるい勉強会vol.2 2022.10.15 knot.
