Dependencies

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

  • camel:core

  • camel:kamelet

  • camel:mongodb

  • camel:jackson

  • mvn:org.apache.camel.kamelets:camel-kamelets-utils:4.0.4-SNAPSHOT

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 mongodb-sink.

Knative sink

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

mongodb-sink-binding.yaml
apiVersion: camel.apache.org/v1
kind: KameletBinding
metadata:
  name: mongodb-sink-binding
spec:
  source:
    ref:
      kind: Channel
      apiVersion: messaging.knative.dev/v1
      name: mychannel
  sink:
    ref:
      kind: Kamelet
      apiVersion: camel.apache.org/v1
      name: mongodb-sink
    properties:
      collection: The MongoDB Collection
      database: The MongoDB Database
      hosts: The MongoDB Hosts

Prerequisite

You have Camel K installed on the cluster.

Procedure for using the cluster CLI

  1. Save the mongodb-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 mongodb-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.collection=The MongoDB Collection" -p "sink.database=The MongoDB Database" -p "sink.hosts=The MongoDB Hosts" mongodb-sink

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

Kafka sink

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

mongodb-sink-binding.yaml
apiVersion: camel.apache.org/v1
kind: KameletBinding
metadata:
  name: mongodb-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: mongodb-sink
    properties:
      collection: The MongoDB Collection
      database: The MongoDB Database
      hosts: The MongoDB Hosts

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 mongodb-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 mongodb-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.collection=The MongoDB Collection" -p "sink.database=The MongoDB Database" -p "sink.hosts=The MongoDB Hosts" mongodb-sink

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