How to configure SingleStore operator to create internal ELB / NLB rather than internet-facing LBs?
{question}
{answer}
For configuring SingleStore operator to create internal ELB / NLB rather than internet-facing LBs, we have an Advance Service configuration section that provides control over this,
The serviceSpec section is an optional section that provides advanced configuration controls over the allocated services to handle DDL and DML queries.
For each service provider, we should check the service provider published annotation, for example for GKE check https://cloud.google.com/kubernetes-engine/docs/how-to/internal-load-balancing#annotation
By adding the GKE service scheduling annotation to the memsql-cluster spec, you can enable internal-facing LoadBalancer IP.
serviceSpec:
type: "LoadBalancer"
externalTrafficPolicy: "Cluster"
objectMetaOverrides:
annotations:
networking.gke.io/load-balancer-type: Internal
This networking.gke.io/load-balancer-type: Internal annotation spec comes from the GKE documentation.
