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.

- camel:core
- camel:aws2-s3
- camel:kamelet
21.3. Usage
This section describes how you can use the ceph-sink.
21.3.1. Knative Sink
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"
21.3.1.1. Prerequisite
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
-
Save the
ceph-sink-binding.yamlfile to your local drive, and then edit it as needed for your configuration. Run the sink by using the following command:
oc apply -f ceph-sink-binding.yaml
21.3.1.3. Procedure for using the Kamel CLI
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"
This command creates the KameletBinding in the current namespace on the cluster.
21.3.2. Kafka Sink
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"
21.3.2.1. 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.
21.3.2.2. Procedure for using the cluster CLI
-
Save the
ceph-sink-binding.yamlfile to your local drive, and then edit it as needed for your configuration. Run the sink by using the following command:
oc apply -f ceph-sink-binding.yaml
21.3.2.3. 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 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"
This command creates the KameletBinding in the current namespace on the cluster.
