# TODO
# This  is  where  the  trouble starts:  In  order  to
# install Nix, one will have to jump in the container,
# and   do  the   interactive   install.  Then   clone
# `slate-2`, and  enter `dev_shell.nix`, which  has an
# interactive step too.
#
# The  solution would  be  to create  a custom  image,
# which is quite forward, but  then where to store it?
# What are the benefits?

# TODO How to expose services in containers?
# There is  port-forwarding, bridging(?),  and reverse
# proxy  (e.g.,  NGINX).  The  last  one  seem  to  be
# the  best option,  because Lynx  already uses  it in
# production,  and it  has  to be  used (or  something
# similar) anyway for enabling HTTPS.
