The cron are responsible for maintaining database up to date and perfom system tasks such as export to xml or backups.
Database can be updated:
- with reference to upstream geokrety.org (export2.php & crawling)
- by consulting a master node (some sort of pull replication)
Use the image tagged as slave or master.
Running as a slave, need a master node. The master node url could be defined using
an environment variable on the gkm-api-basex container. The default value is
api.geokretymap.org.
