MongoDB is document database that supports range and field queries.

Replication

A single server can run either standalone or as part of a replica set. A "replica set" is set of mongod instances with 1 primary. Primary: receives writes, services reads. Can step down and become secondary. Secondary: replicate the primary's oplog. If the primary goes down, secondaries will hold an election. Arbiter: used to achieve majority vote with even members, do not hold data, don't need dedicated nodes. Never becomes primary.

First make your service type=NodePort

Then create an instance group in UI (console.cloud.google.com), with some pool of instances from one of your zones:

gcloud compute --project $PROJECT instance-groups create unmanaged $K8S_IG
gcloud compute --project $PROJECTinstance-groups unmanaged add-instances $K8S_IG --instances $NODE,$NODE_1...

Add the Service NodePort to the InstanceGroup:

gcloud compute --project $PROJECT instance-groups set-named-ports $K8S_G --named-ports svc1:$SVC1_NODE_PORT
