OSM tile server with Guix

OSM tile server with Guix

Hi

I read up on how to setup a tile server with the least hassle. It is
quite a bit involved according to this guide:
https://switch2osm.org/manually-building-a-tile-server-18-04-lts/

I imagine this could be more fully automated with guix if we find a way
to run the pgsql-commands from guile and write the necessary services.

We have most of the bits and pieces already but I spotted a few that
were missing while reading and thought I would share them here:

* mod_tile (apache plugin) https://github.com/openstreetmap/mod_tile
* carto (uses npm and node) https://www.npmjs.com/package/carto (7
dependencies - at least 1 with a lot of dependencies (yargs))
* openstreetmap-carto (contain carto-css styles and a lua-script useful
for tag-transformation when loading pbf-files into a postgis database
with osm2pgsql and get-shapefiles.py a script to download low-zoom
country boundaries) https://github.com/gravitystorm/openstreetmap-carto/

This last one should perhaps be included in our osm2pgsql-package
because it is hard to imagine someone using one but not the other.

It seems we need a renderd-service also.

Thoughts?

Ok.

Ok, I will add packaging openstreetmap-carto to my list.

Renderd comes with mod_tile.

Yes, that woul make sense.

My usecases usually can be solved using hand-authored styles, but would be
nice to have. (Carto usually created something very bloated for me)

I sometimes use osm2pgsql without any need for rendering, so when using
the database not for rendering, but as a database, these functions are
not needed.
I would keep these separate. Wdyt?

Hey,

I've had some experience with tile servers, but this was a little while
ago when I was still using Debian.

I wrote up some documentation for Debian, but that might be useful when
looking at how to configure the relevant services within Guix [1].

1: https://wiki.debian.org/OSM/tileserver/jessie

I'd love to see it being easy to setup a tile server with Guix :)
