Infrastructure

Notes

Maps nodes

• eqiad cluster
  • maps{1005..1010}.eqiad.wmnet
    • master node: 1009
    • read replicas: 1005,1006,1006,1008,1010

• codfw
  • maps{2005..2010}.codfw.wmnet
    • master node: 1009
    • read replicas: 1005,1006,1006,1008,1010

Each of the nodes runs:

• Postgres/Postgis
• Kartotherian
• (Deprecated) Redis + Cassandra + Tilerator
  • Tilerator will be phased out when Tegola is ready for production traffic

For master nodes specifically we also run:

• OpenStreetMap data import script backed by imposm3
  • The PostgresSQL DB receives writes only on master nodes the rest of the access is read-only.

Kubernetes

We currently host tegola on kubernetes

• codfw deploymet --> maps codfw postgres read replicas
• eqiad deployment --> maps eqiad postgres read replicas
