What is IgniteOpsRequest
IgniteOpsRequest is a Kubernetes Custom Resource Definitions (CRD). It provides a declarative configuration for Ignite administrative operations like database version updating, horizontal scaling, vertical scaling etc. in a Kubernetes native way.

Here, we are going to describe the various sections of a IgniteOpsRequest crd.
A IgniteOpsRequest object has the following fields in the spec section.
spec.databaseRef
spec.databaseRef is a required field that point to the Ignite object for which the administrative operations will be performed. This field consists of the following sub-field:
- spec.databaseRef.name : specifies the name of the Ignite object.
