Chapter 16. ElasticSearch Index Sink
The ElasticSearch Index Kamelet is a Technology Preview feature only. Technology Preview features are not supported with Red Hat production service level agreements (SLAs) and might not be functionally complete. Red Hat does not recommend using them in production.
These features provide early access to upcoming product features, enabling customers to test functionality and provide feedback during the development process. For more information about the support scope of Red Hat Technology Preview features, see https://access.redhat.com/support/offerings/techpreview.
This sink stores documents into ElasticSearch.
Input data must have JSON format according to the index used.
The Kamelet expects the following headers:
-
indexId
/ce-indexid
: as the index ID for Elasticsearch
If the header won’t be set, the index will be generated by the ES Cluster.
-
indexName
/ce-indexname
: as the index Name for Elasticsearch
If the header is not set, camel-k-index-es
will be used as the index name.

This section describes how you can use the elasticsearch-index-sink
.
16.3.1. Knative Sink 复制链接链接已复制到粘贴板!
You can use the elasticsearch-index-sink
Kamelet as a Knative sink by binding it to a Knative object.
elasticsearch-index-sink-binding.yaml
16.3.1.1. Prerequisite 复制链接链接已复制到粘贴板!
Make sure you have "Red Hat Integration - Camel K" installed into the OpenShift cluster you’re connected to.
16.3.1.2. Procedure for using the cluster CLI 复制链接链接已复制到粘贴板!
-
Save the
elasticsearch-index-sink-binding.yaml
file to your local drive, and then edit it as needed for your configuration. Run the sink by using the following command:
oc apply -f elasticsearch-index-sink-binding.yaml
oc apply -f elasticsearch-index-sink-binding.yaml

16.3.1.3. Procedure for using the Kamel CLI 复制链接链接已复制到粘贴板!
Configure and run the sink by using the following command:
kamel bind channel:mychannel elasticsearch-index-sink -p "sink.clusterName=quickstart" -p "sink.hostAddresses=quickstart-es-http:9200"
kamel bind channel:mychannel elasticsearch-index-sink -p "sink.clusterName=quickstart" -p "sink.hostAddresses=quickstart-es-http:9200"
This command creates the KameletBinding in the current namespace on the cluster.
16.3.2. Kafka Sink 复制链接链接已复制到粘贴板!
You can use the elasticsearch-index-sink
Kamelet as a Kafka sink by binding it to a Kafka topic.
elasticsearch-index-sink-binding.yaml
16.3.2.1. Prerequisites 复制链接链接已复制到粘贴板!
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.
16.3.2.2. Procedure for using the cluster CLI 复制链接链接已复制到粘贴板!
-
Save the
elasticsearch-index-sink-binding.yaml
file to your local drive, and then edit it as needed for your configuration. Run the sink by using the following command:
oc apply -f elasticsearch-index-sink-binding.yaml
oc apply -f elasticsearch-index-sink-binding.yaml
Copy to Clipboard Copied! Toggle word wrap Toggle overflow
16.3.2.3. Procedure for using the Kamel CLI 复制链接链接已复制到粘贴板!
Configure and run the sink by using the following command:
kamel bind kafka.strimzi.io/v1beta1:KafkaTopic:my-topic elasticsearch-index-sink -p "sink.clusterName=quickstart" -p "sink.hostAddresses=quickstart-es-http:9200"
kamel bind kafka.strimzi.io/v1beta1:KafkaTopic:my-topic elasticsearch-index-sink -p "sink.clusterName=quickstart" -p "sink.hostAddresses=quickstart-es-http:9200"
This command creates the KameletBinding in the current namespace on the cluster.
