elasticsearch index sink ElasticSearch Index Sink

Provided by: "Apache Software Foundation"

Support Level for this Kamelet is: "Stable"

Stores JSON-formatted data into ElasticSearch.

The input data must be formatted in JSON according to the requirements of the index.

If you specify the certificate property, you must base64 encode it before you pass it as a parameter.

In the header, you can set the following properties:

  • indexId / ce-indexid: The index ID for ElasticSearch.

  • indexName / ce-indexname: The index name for ElasticSearch.

If you do not set a property in the header, the Kamelet uses the exchange ID for the index setting.

Dependencies

At runtime, the elasticsearch-index-sink Kamelet relies upon the presence of the following dependencies:

  • camel:core

  • camel:jackson

  • camel:kamelet

  • camel:elasticsearch

  • camel:gson

  • camel:bean

Camel JBang usage

Prerequisites

  • You’ve installed JBang.

  • You have executed the following command:

jbang app install camel@apache/camel

Supposing you have a file named route.yaml with this content:

- route:
    from:
      uri: "kamelet:timer-source"
      parameters:
        period: 10000
        message: 'test'
      steps:
        - to:
            uri: "kamelet:log-sink"

You can now run it directly through the following command

camel run route.yaml

Camel K Environment Usage

This section describes how you can use the elasticsearch-index-sink.

Knative sink

You can use the elasticsearch-index-sink Kamelet as a Knative sink by binding it to a Knative object.

elasticsearch-index-sink-binding.yaml
apiVersion: camel.apache.org/v1
kind: KameletBinding
metadata:
  name: elasticsearch-index-sink-binding
spec:
  source:
    ref:
      kind: Channel
      apiVersion: messaging.knative.dev/v1
      name: mychannel
  sink:
    ref:
      kind: Kamelet
      apiVersion: camel.apache.org/v1
      name: elasticsearch-index-sink
    properties:
      clusterName: quickstart
      hostAddresses: quickstart-es-http:9200

Prerequisite

You have Camel K installed on the cluster.

Procedure for using the cluster CLI

  1. Save the elasticsearch-index-sink-binding.yaml file to your local drive, and then edit it as needed for your configuration.

  2. Run the sink by using the following command:

    kubectl apply -f elasticsearch-index-sink-binding.yaml

Procedure for using the Kamel CLI

Configure and run the sink by using the following command:

kamel bind channel:mychannel -p "sink.clusterName=quickstart" -p "sink.hostAddresses=quickstart-es-http:9200" elasticsearch-index-sink

This command creates the KameletBinding in the current namespace on the cluster.

Kafka sink

You can use the elasticsearch-index-sink Kamelet as a Kafka sink by binding it to a Kafka topic.

elasticsearch-index-sink-binding.yaml
apiVersion: camel.apache.org/v1
kind: KameletBinding
metadata:
  name: elasticsearch-index-sink-binding
spec:
  source:
    ref:
      kind: KafkaTopic
      apiVersion: kafka.strimzi.io/v1beta1
      name: my-topic
  sink:
    ref:
      kind: Kamelet
      apiVersion: camel.apache.org/v1
      name: elasticsearch-index-sink
    properties:
      clusterName: quickstart
      hostAddresses: quickstart-es-http:9200

Prerequisites

  • You’ve installed Strimzi.

  • You’ve created a topic named my-topic in the current namespace.

  • You have Camel K installed on the cluster.

Procedure for using the cluster CLI

  1. Save the elasticsearch-index-sink-binding.yaml file to your local drive, and then edit it as needed for your configuration.

  2. Run the sink by using the following command:

    kubectl apply -f elasticsearch-index-sink-binding.yaml

Procedure for using the Kamel CLI

Configure and run the sink by using the following command:

kamel bind kafka.strimzi.io/v1beta1:KafkaTopic:my-topic -p "sink.clusterName=quickstart" -p "sink.hostAddresses=quickstart-es-http:9200" elasticsearch-index-sink

This command creates the KameletBinding in the current namespace on the cluster.
