Class CustomResourceConditions

java.lang.Object

io.strimzi.api.kafka.model.common.CustomResourceConditions

public class CustomResourceConditions
extends Object

CustomResourceConditions supplies convenience predicates that are intended to reduce boilerplate code when using fabric8 clients to wait for a CRD to enter some anticipated state. This class provides a generic implementation that can be used internally, public Predicates are exposed on the CRD classes.

An example usage of one of the public predicates (Kafka::isReady):

 Crds.kafkaOperation(client).inNamespace(NAMESPACE).resource(kafka).create();
 Crds.kafkaOperation(client).inNamespace(NAMESPACE).withName(NAME).waitUntilCondition(Kafka.isReady(), 5, TimeUnit.MINUTES);
 

and to wait on a specific KafkaRebalance state using KafkaRebalance::isInState:

 Crds.kafkaRebalanceOperation(client).inNamespace(NAMESPACE).withName(REBALANCE_NAME)
     .waitUntilCondition(KafkaRebalance.isInState(KafkaRebalanceState.ProposalReady), 5, TimeUnit.MINUTES);

Method Details

isReady

public static <Y extends Status,
T extends io.fabric8.kubernetes.client.CustomResource<?,
Y>>
Predicate<T> isReady()

Returns a predicate that determines if CRD is ready. A CRD is ready if the observedGeneration of its status is equal to the generation of its metadata and any of the conditions of its status has type:"Ready" and status:"True"

Returns:

a predicate that checks if a CRD is ready

isLatestGenerationAndAnyConditionMatches

public static <Y extends Status,
T extends io.fabric8.kubernetes.client.CustomResource<?,
Y>>
Predicate<T> isLatestGenerationAndAnyConditionMatches(String type,
 String status)

Checks if the observedGeneration of its status is equal to the generation of its metadata and any of the conditions of its status contains given type and status parameter.

Type Parameters:

Y - Type of status

T - Type of Custom resource

Parameters:

type - State of the Custom resource

status - Status of the Custom resource

Returns:

a predicate based on the check
