Plugins ignores base_url and takes hostname instead

[sergio-ns]

Hello,
I'm running jekyll off a docker container and would like to redirect to 404.html attempts to open folder /assets/
The plugins gets installed during the container creation process:

Successfully installed jekyll-redirect-from-0.16.0
1 gem installed

In 404.html I added:

---
permalink: /404.html
layout: default
redirect_from:
- /assets/
---

In _config.yml I have:

baseurl: "" # the subpath of your site, e.g. /blog
url: "http://mysite.mydomain.com" # the base hostname & protocol for your site, e.g. http://example.com

When jekyll-serve starts an index.html is actually created in folder /assets but the the redirect URL is not using the base_url settings, rather the host name:

  <link rel="canonical" href="http://127.0.0.1:4000/404.html">
  <script>location="http://127.0.0.1:4000/404.html"</script>
  <meta http-equiv="refresh" content="0; url=http://127.0.0.1:4000/404.html">

which obviously won't work.

I would expect that the redirect location were instead:
<link rel="canonical" href="http://mysite.mydomain.com/404.html">

What am I doing wrong?
Thanks
S.
