Chapter 51. MongoDB Sink Send documents to MongoDB. This Kamelet expects a JSON as body. Properties you can set as headers: db-upsert / ce-dbupsert : if the database should create the element if it does not exist. Boolean value. 51.1. Configuration Options The following table summarizes the configuration options available for the mongodb-sink Kamelet: Property Name Description Type Default Example collection * MongoDB Collection Sets the name of the MongoDB collection to bind to this endpoint. string database * MongoDB Database Sets the name of the MongoDB database to target. string hosts * MongoDB Hosts Comma separated list of MongoDB Host Addresses in host:port format. string createCollection Collection Create collection during initialisation if it doesn't exist. boolean false password MongoDB Password User password for accessing MongoDB. string username MongoDB Username Username for accessing MongoDB. string writeConcern Write Concern Configure the level of acknowledgment requested from MongoDB for write operations, possible values are ACKNOWLEDGED, W1, W2, W3, UNACKNOWLEDGED, JOURNALED, MAJORITY. string Note Fields marked with an asterisk (*) are mandatory. 51.2. Dependencies At runtime, the mongodb-sink Kamelet relies upon the presence of the following dependencies: camel:kamelet camel:mongodb camel:jackson 51.3. Usage This section describes how you can use the mongodb-sink . 51.3.1. 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/v1alpha1 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/v1alpha1 name: mongodb-sink properties: collection: "The MongoDB Collection" database: "The MongoDB Database" hosts: "The MongoDB Hosts" 51.3.1.1. Prerequisite Make sure you have "Red Hat Integration - Camel K" installed into the OpenShift cluster you're connected to. 51.3.1.2. Procedure for using the cluster CLI Save the mongodb-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 mongodb-sink-binding.yaml 51.3.1.3. Procedure for using the Kamel CLI Configure and run the sink by using the following command: kamel bind channel:mychannel mongodb-sink -p "sink.collection=The MongoDB Collection" -p "sink.database=The MongoDB Database" -p "sink.hosts=The MongoDB Hosts" This command creates the KameletBinding in the current namespace on the cluster. 51.3.2. 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/v1alpha1 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/v1alpha1 name: mongodb-sink properties: collection: "The MongoDB Collection" database: "The MongoDB Database" hosts: "The MongoDB Hosts" 51.3.2.1. Prerequisites 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. 51.3.2.2. Procedure for using the cluster CLI Save the mongodb-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 mongodb-sink-binding.yaml 51.3.2.3. 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 mongodb-sink -p "sink.collection=The MongoDB Collection" -p "sink.database=The MongoDB Database" -p "sink.hosts=The MongoDB Hosts" This command creates the KameletBinding in the current namespace on the cluster. 51.4.
