Caddy not rendering assets


I have a rails application that is not rendering assets. It was previously working fine. When I added linked files it not only uploaded the files I specified but also precompiled assets. Even after clobbering all assets and recompiling it fails to render them even though that exist on the box.

error enter image description here

Solution

  • I was able to get this working but using the fileserver directive.

    https://example.com {
      encode zstd gzip
      root * /home/deploy/apps/rails-app/current/public
      file_server
      tls user@email.com
      @notStatic {
         not file
      }
      reverse_proxy @notStatic unix//home/deploy/apps/rails-app/shared/tmp/sockets/rails-app-puma.sock
    
      header / {
        Strict-Transport-Security "max-age=31536000"
      }
    }
