docekrでpdfの投稿ができない(pdfをpngに変換したい)

□解決したいこと

dockerの初心者です。

現在、dockerをrailsアプリケーションに導入しようと考えております。

docker-composeでdockerを起動し、localhostで投稿しようとしたところ、pdf投稿のみできません。

doker導入前の正しい挙動

docker-compose時の挙動

https://gyazo.com/11fdbcefd336a4ae84bca8eb818442ab

状況の確認

当該、pdfの投稿はcarrier waveとrmagicを用いて、pdfの投稿をしております。
投稿した際、pdfをpngに変換してトップページに表示するしようとしております。
jpegやpngの投稿は問題なくできます。
指定したディレクトリの中にpdfは保存されていました。https://gyazo.com/fc0a517116caff7f1b8c1f9b6237725d
pdfをpngに変換したファイルは生成されていなかった。
データベースにも投稿がありませんでした。

→以上より、まずはpdfをpngに変換できないことを解決したいのですが、アドバイスいただけましたら幸いです。

□仮説及び調べたこと

pdfは保存できているが、pngが生成していなかったことから、変換するpdf⇒pngに変換するrmagic,もしくはcarrierwaveの記述に問題があるのではないか？と思い調べてみました。

⇒https://qiita.com/minojiro/items/879616c3569277572859

上記の記事ではbundleinstall前に'apk add'を記述することでRmagic,Carriewwaveを使用可能とのことでした。こちらを参考にdockerfileを変更しました。
