 StrimziOperatorController operatorController,
 io.fabric8.openshift.client.OpenShiftClient ocp,
 okhttp3.OkHttpClient http)

Method Details

disable

public void disable()

Disables Kafka Connect by scaling it to ZERO

NOTICE: cluster operator needs to be disabled first!

Specified by:

disable in interface KafkaConnectController

destroy

public void destroy()

Crashes Kafka Connect by force deleting all pods. Then it immediately scales its deployment to ZERO by calling disable()

NOTICE: cluster operator is disabled once this method is called!

Specified by:

destroy in interface KafkaConnectController

restore

public void restore()
             throws InterruptedException

Description copied from interface: KafkaConnectController

Restores Kafka Connect cluster after a call to KafkaConnectController.disable() or KafkaConnectController.destroy()

Specified by:

restore in interface KafkaConnectController

Throws:

InterruptedException

waitForCluster

public void waitForCluster()
                    throws InterruptedException

Wait until KafkaConnect instance is back and ready

Specified by:

waitForCluster in interface KafkaConnectController

Throws:

InterruptedException

allowServiceAccess

public io.fabric8.kubernetes.api.model.networking.v1.NetworkPolicy allowServiceAccess()

Creates network policy allowing access to ports exposed by Kafka Connect

Returns:

exposeApi

public io.fabric8.openshift.api.model.Route exposeApi()

Exposes a route for kafka connect API associated with given KafkaConnect resource

Returns:

exposeMetrics

public io.fabric8.openshift.api.model.Route exposeMetrics()

Exposes a route for prometheus metrics for kafka connect associated with given KafkaConnect resource

Returns:

Route object

deployConnector

public void deployConnector(ConnectorConfigBuilder config)
                     throws IOException,
InterruptedException

Deploys Kafka connector with given name and configuration via REST

Specified by:

Specified by:

undeployConnector in interface KafkaConnectController

Parameters:

name - connector name

Throws:

IOException - on request error

getApiURL

public okhttp3.HttpUrl getApiURL()

Specified by:

getApiURL in interface KafkaConnectController

Returns:

URL of Connect API endpoint

getMetricsURL

public okhttp3.HttpUrl getMetricsURL()

Returns:

URL of metrics endpoint

undeploy

public boolean undeploy()

Undeploy this Kafka Connect cluster by deleted related KafkaConnect CR

Specified by:

undeploy in interface KafkaConnectController

Returns:

true if the CR was found and deleted
