I'm really not sure how this relates in any way to Perl.

Again, note that a Mojolicious program does not need any web server, as you can launch it via

perl -w records1 daemon -l http://example.com:80/
[download]

Most likely, you can bundle your Mojolicious application in a Dockerfile by following the Instructions on the Mojolicious wiki.

The Docker error tells you that a file, httpd.conf cannot be found for copying into the Docker image. Usually that means you are in the wrong directory. But this is Perlmonks, not Dockermonks.
