43.3.1.1. Prerequisite 링크 복사링크가 클립보드에 복사되었습니다!
Make sure you have "Red Hat Integration - Camel K" installed into the OpenShift cluster you’re connected to.
43.3.1.2. Procedure for using the cluster CLI 링크 복사링크가 클립보드에 복사되었습니다!
-
Save the
kafka-sink-binding.yamlfile to your local drive, and then edit it as needed for your configuration. Run the sink by using the following command:
oc apply -f kafka-sink-binding.yaml
oc apply -f kafka-sink-binding.yamlCopy to Clipboard Copied! Toggle word wrap Toggle overflow
43.3.1.3. Procedure for using the Kamel CLI 링크 복사링크가 클립보드에 복사되었습니다!
Configure and run the sink by using the following command:
kamel bind channel:mychannel kafka-sink -p "sink.bootstrapServers=The Brokers" -p "sink.password=The Password" -p "sink.topic=The Topic Names" -p "sink.user=The Username"
kamel bind channel:mychannel kafka-sink -p "sink.bootstrapServers=The Brokers" -p "sink.password=The Password" -p "sink.topic=The Topic Names" -p "sink.user=The Username"
