Deployment and Development

Frontend

The frontend container contains the cherrypy based service and an nginx based reverse proxy for exposing the mapgen on port 9090 Both processes in the frontend container are started by supervisord.

Frontend produces job files that are put into a shared volume

/opt/mapgen/jobs/<jobid>.queued

Worker

This is the actual map builder, that takes the queued jobs in /opt/mapgen/jobs/jobid and starts processing all the *.queued jobs.

Volumes

These are named volumes inside your docker service.

/opt/mapgen/jobs:

This is the job directory where all jobs get stored

/opt/mapgen/data:

This directory caches all the data from the data repository. WARNING: This volume can take up a lot of space (100GB).

Ports

Port 9090
