stylesheet_link_tagがassets配下を読み込まない

お世話になっております。
railsで添付のようにstylesheet_link_tagがassets配下を読み込んでくれず、application.cssが適用されません。
確認するべきファイルなどございますでしょうか？
関係あるかはわかりませんが、Dockerを使用しています。

erb
1<!DOCTYPE html>
2<html>
3  <head>
4    <title>Api</title>
5    <%= csrf_meta_tags %>
6    <%= csp_meta_tag %>
7
8    <%= stylesheet_link_tag 'application', media: 'all', 'data-turbolinks-track': 'reload' %>
9    <%= javascript_pack_tag 'application', 'data-turbolinks-track': 'reload' %>
10  </head>
11
12  <body>
13    <%= yield %>
14  </body>
15</html>

6 * vendor/assets/stylesheets directory can be referenced here using a relative path.

8 * You're free to add application-wide styles to this file and they'll appear at the bottom of the
9 * compiled file so the styles you add here take precedence over styles defined in any other CSS/SCSS
