20.2. Dependencies 링크 복사링크가 클립보드에 복사되었습니다!
At runtime, the cassandra-source
Kamelet relies upon the presence of the following dependencies:
- camel:jackson
- camel:kamelet
- camel:cassandraql
20.3. Usage 링크 복사링크가 클립보드에 복사되었습니다!
This section describes how you can use the cassandra-source
.
20.3.1. Knative Source 링크 복사링크가 클립보드에 복사되었습니다!
You can use the cassandra-source
Kamelet as a Knative source by binding it to a Knative object.
cassandra-source-binding.yaml
20.3.1.1. Prerequisite 링크 복사링크가 클립보드에 복사되었습니다!
Make sure you have "Red Hat Integration - Camel K" installed into the OpenShift cluster you’re connected to.
20.3.1.2. Procedure for using the cluster CLI 링크 복사링크가 클립보드에 복사되었습니다!
-
Save the
cassandra-source-binding.yaml
file to your local drive, and then edit it as needed for your configuration. Run the source by using the following command:
oc apply -f cassandra-source-binding.yaml
oc apply -f cassandra-source-binding.yaml
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
20.3.1.3. Procedure for using the Kamel CLI 링크 복사링크가 클립보드에 복사되었습니다!
Configure and run the source by using the following command:
kamel bind cassandra-source -p "source.connectionHost=localhost" -p source.connectionPort=9042 -p "source.keyspace=customers" -p "source.password=The Password" -p "source.query=The Query" -p "source.username=The Username" channel:mychannel
kamel bind cassandra-source -p "source.connectionHost=localhost" -p source.connectionPort=9042 -p "source.keyspace=customers" -p "source.password=The Password" -p "source.query=The Query" -p "source.username=The Username" channel:mychannel
This command creates the KameletBinding in the current namespace on the cluster.
20.3.2. Kafka Source 링크 복사링크가 클립보드에 복사되었습니다!
You can use the cassandra-source
Kamelet as a Kafka source by binding it to a Kafka topic.
cassandra-source-binding.yaml
20.3.2.1. Prerequisites 링크 복사링크가 클립보드에 복사되었습니다!
Ensure that you’ve installed the AMQ Streams operator in your OpenShift cluster and created a topic named my-topic
in the current namespace. Make also sure you have "Red Hat Integration - Camel K" installed into the OpenShift cluster you’re connected to.

20.3.2.3. Procedure for using the Kamel CLI 링크 복사링크가 클립보드에 복사되었습니다!
Configure and run the source by using the following command:
kamel bind cassandra-source -p "source.connectionHost=localhost" -p source.connectionPort=9042 -p "source.keyspace=customers" -p "source.password=The Password" -p "source.query=The Query" -p "source.username=The Username" kafka.strimzi.io/v1beta1:KafkaTopic:my-topic
kamel bind cassandra-source -p "source.connectionHost=localhost" -p source.connectionPort=9042 -p "source.keyspace=customers" -p "source.password=The Password" -p "source.query=The Query" -p "source.username=The Username" kafka.strimzi.io/v1beta1:KafkaTopic:my-topic
This command creates the KameletBinding in the current namespace on the cluster.
