Kubernetes - Operators and Custom Resources

What will happen if you apply this PostgreSQL operator manifest with 'storage.size' set to '10Gi'? apiVersion: postgres-operator.crunchydata.io/v1 kind: PostgresCluster metadata: name: pg-cluster spec: storage: size: 10Gi

AThe storage size will default to 1Gi

BA PersistentVolumeClaim of 10Gi will be created for the database

CThe operator will throw a syntax error

DThe database will run without persistent storage

Step-by-Step Solution

Solution:

Step 1: Understand storage.size field
This field defines the size of persistent storage requested for the database.
Step 2: Operator creates PersistentVolumeClaim
The operator uses this size to create a PVC to store database data persistently.
Final Answer:
A PersistentVolumeClaim of 10Gi will be created for the database -> Option B
Quick Check:
storage.size sets PVC size = 10Gi [OK]

Quick Trick: storage.size defines PVC size for database data [OK]

Common Mistakes:

Assuming no storage is created
Expecting syntax error for size format
Thinking default size overrides specified size
