What

Capture resource requirements for the DNS-Operator (Mem and CPU) for setting limits via k8s

• minimum:
  • 1 gateway,
  • 1 listener,
  • 1 DNSPolicy (with health check)
• baseline:
  • 1 gateway,
  • 64 listeners,
  • 1 DNSPolicy (with health check)
• baseline +1:
  • 2 gateways with:
  • 64 listeners,
  • 1 DNSPolicy (with health check)

Can just use DNSRecords but might be easier with DNSPolicy.

Increase limits based on diff between baseline and baseline +1

Make use of Grafana and Prometheus to take measurements.

Could be useful as a pipeline that can output suggested limits, which we can reuse on every release.

@philbrookes @mikenairn above make sense as a method for coming up with some baseline numbers?
