Operators
● Modern distributed systems
are declarative
● Native extension point for
Kubernetes
● Enabler for over-the-air

Custom Resource Definition
The Kubernetes object end-users create and manage
kind: EtcdCluster
metadata:
name: example
spec:
size: 3
version: "3.2.13"

14. kind: CompliantDatabase
metadata:
name: example-db
spec:
replicationFactor: 2
autoscale: true
backup: hourly
geography:
restriction: EU
preference: Germany

Custom Resource Definition
A more complicated example for a database that is “smart”

Operator Success
Using the Prometheus Operator, our dev teams are able
to provision their own end-to-end monitoring. We could
not hope to manage the 344 Prometheus instances
without the domain knowledge the Operator
encapsulates.

● You decide if open-source
or not
