Docker for local development

[lostfocus]

I've thrown some docker config files and a few lines of readme together for local development after reading #30

I really hope nobody thinks this would be ready for public deployment but it works fine as a development setup.

This looks basically perfect, thanks so much @lostfocus!

Unfortunately, this does no longer work – Dockerfile buildscript can't install debian software anymore

I haven't tried the setup for this project in quite some time, but I use a similar one with a more modern PHP version in other projects without any problem.

At which point does it stop and what is the error message?

There were some warnings along the way so together with the final error it is:

W: GPG error: http://deb.debian.org jessie Release: The following signatures were invalid: KEYEXPIRED 1668891673
WARNING: The following packages cannot be authenticated!
  libpopt0 libxau6 libxcb1 libxext6 libxmuu1 less liberror-perl xauth
E: There are problems and -y was used without --force-yes

So it does not even get to the phase where it builds the extensions.

However if I change php image to php:7.4-apache-bullseye, it works all the way up. I am just having some issues doing artisan migrate, but this I am going to dig in later.
