= Using schema properties to configure custom resources

[role="_abstract"]
Custom resources offer a flexible way to manage and fine-tune the operation of Strimzi components using configuration properties. 
This reference guide describes common configuration properties that apply to multiple custom resources, as well as the configuration properties available for each custom resource schema available with Strimzi.
Where appropriate, expanded descriptions of properties and examples of how they are configured are provided. 

The properties defined for each schema provide a structured and organized way to specify configuration for the custom resources. 
Whether it's adjusting resource allocation or specifying access controls, the properties in the schemas allow for a granular level of configuration.
For example, you can use the properties of the `KafkaClusterSpec` schema to specify the type of storage for a Kafka cluster or add listeners that provide secure access to Kafka brokers. 

Some property options within a schema may be constrained, as indicated in the property descriptions. 
These constraints define specific options or limitations on the values that can be assigned to those properties. 
Constraints ensure that the custom resources are configured with valid and appropriate values.
