Change mapnik.xml style

[vchen0]

I'm new to openstreetmaps and docker and was wondering is there a simple way to update the map style.

My understanding is that I can edit the style files in openstreetmap-carto and then build the xml with carto using
carto project.mml > mapnik.xml
But then I'm not sure what to do with mapnik.xml.

I followed the switch2osm docker tutorial and run the container using
docker run -p 8080:80 -v openstreetmap-data:/var/lib/postgresql/12/main -d overv/openstreetmap-tile-server:1.3.10 run

Is there a way to simply point the docker container to the new mapnik.xml? Sorry if that question doesn't make sense (I'm not familiar with how docker functions).

You can use -v to substitute the file

there are several ways. you can modifiy Dockerfile to COPY the mapnik.xml from your computer to docker during "docker build ." command. That will take the file and copy to docker, build it, and they if you do your normal "docker run", it will use it.
you can also modify mapnik.xml inside the container by running "docker exec -it DOCKERNAME bash" that will run bash command line INSIDE the docker and connect you to it. Then you can modify the xml manually, download (via wget) some replacement etc. Please not this will NOT survive new build command, but will stay during restart of the docker. Durable solution is to dig a bit into the docker build and dockerfile.

One example of doing the copy/import of the newly regenerated mapnik.xml on docker-compose file will be nice for us rookies ;)
