Ruby on Rails - PDF not showing in production mode with Docker

Question

I'm having a hard time figureing out the solution to my problem. I have a ror application running in Docker. In development, the uploaded pdf get stored in ./storage directory and they got rendered as expected on my application. In production, get uploaded in the same directory, but they don't get displayed. I have checked the permissions on the directory and files and they seems to be ok.

My config:

storage.yml:

local:
  service: Disk
  root: <%= Rails.root.join("storage") %>

production.rb:

config.active_storage.service = :local

_attachment.html.erb:

<% if territory.file.previewable? %>
  <div class="container">
    <embed type="application/pdf" src="<%= rails_blob_path(@territory.file, disposition: :inline) %>" width="100%" height="500px">
  </div>
<% end %>

This partial gets rendered in my view like this:

<p>
  <%= render "territories/attachment", territory: territory %>
</p>

Am I missing something? Thanks for any help and stay save out there!
