Chapter 21. Ceph Sink

Upload data to an Ceph Bucket managed by a Object Storage Gateway.

In the header, you can optionally set the file / ce-file property to specify the name of the file to upload.

If you do not set the property in the header, the Kamelet uses the exchange ID for the file name.

21.3. Usage
Copy link

This section describes how you can use the ceph-sink.

21.3.1. Knative Sink
Copy link

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

ceph-sink-binding.yaml

apiVersion: camel.apache.org/v1alpha1
kind: KameletBinding
metadata:
  name: ceph-sink-binding
spec:
  source:
    ref:
      kind: Channel
      apiVersion: messaging.knative.dev/v1
      name: mychannel
  sink:
    ref:
      kind: Kamelet
      apiVersion: camel.apache.org/v1alpha1
      name: ceph-sink
    properties:
      accessKey: "The Access Key"
      bucketName: "The Bucket Name"
      cephUrl: "http://ceph-storage-address.com"
      secretKey: "The Secret Key"
      zoneGroup: "The Bucket Zone Group"
Copy to Clipboard Toggle word wrap

21.3.1.1. Prerequisite
Copy link

Make sure you have "Red Hat Integration - Camel K" installed into the OpenShift cluster you’re connected to.

21.3.1.2. Procedure for using the cluster CLI
Copy link

  1. Save the ceph-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: 

    oc apply -f ceph-sink-binding.yaml
    Copy to Clipboard Toggle word wrap

21.3.1.3. Procedure for using the Kamel CLI
Copy link

Configure and run the sink by using the following command: 

kamel bind channel:mychannel ceph-sink -p "sink.accessKey=The Access Key" -p "sink.bucketName=The Bucket Name" -p "sink.cephUrl=http://ceph-storage-address.com" -p "sink.secretKey=The Secret Key" -p "sink.zoneGroup=The Bucket Zone Group"
Copy to Clipboard Toggle word wrap

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

21.3.2. Kafka Sink
Copy link

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

ceph-sink-binding.yaml

apiVersion: camel.apache.org/v1alpha1
kind: KameletBinding
metadata:
  name: ceph-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: ceph-sink
    properties:
      accessKey: "The Access Key"
      bucketName: "The Bucket Name"
      cephUrl: "http://ceph-storage-address.com"
      secretKey: "The Secret Key"
      zoneGroup: "The Bucket Zone Group"
Copy to Clipboard Toggle word wrap

21.3.2.1. Prerequisites
Copy link

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.

21.3.2.2. Procedure for using the cluster CLI
Copy link

  1. Save the ceph-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: 

    oc apply -f ceph-sink-binding.yaml
    Copy to Clipboard Toggle word wrap

21.3.2.3. Procedure for using the Kamel CLI
Copy link

Configure and run the sink by using the following command: 

kamel bind kafka.strimzi.io/v1beta1:KafkaTopic:my-topic ceph-sink -p "sink.accessKey=The Access Key" -p "sink.bucketName=The Bucket Name" -p "sink.cephUrl=http://ceph-storage-address.com" -p "sink.secretKey=The Secret Key" -p "sink.zoneGroup=The Bucket Zone Group"
Copy to Clipboard Toggle word wrap

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