| Property | Name | Description | Type | Default | Example |
|---|---|---|---|---|---|
| accessKey * | Access Key | The access key. | string | ||
| bucketName * | Bucket Name | The Ceph Bucket name. | string | ||
| cephUrl * | Ceph Url Address | Set the Ceph Object Storage Address Url. | string |
| |
| secretKey * | Secret Key | The secret key. | string | ||
| zoneGroup * | Bucket Zone Group | The bucket zone group. | string | ||
| autoCreateBucket | Autocreate Bucket | Specifies to automatically create the bucket. | boolean |
| |
| delay | Delay | The number of milliseconds before the next poll of the selected bucket. | integer |
| |
| deleteAfterRead | Auto-delete Objects | Specifies to delete objects after consuming them. | boolean |
| |
| ignoreBody | Ignore Body |
If true, the Object body is ignored. Setting this to true overrides any behavior defined by the | boolean |
| |
| includeBody | Include Body | If true, the exchange is consumed and put into the body and closed. If false, the Object stream is put raw into the body and the headers are set with the object metadata. | boolean |
| |
| prefix | Prefix | The bucket prefix to consider while searching. | string |

22.2. Dependencies
At runtime, the ceph-source Kamelet relies upon the presence of the following dependencies:
- camel:aws2-s3
- camel:kamelet
22.3. Usage
This section describes how you can use the ceph-source.
22.3.1. Knative Source
You can use the ceph-source Kamelet as a Knative source by binding it to a Knative object.
ceph-source-binding.yaml
apiVersion: camel.apache.org/v1alpha1
kind: KameletBinding
metadata:
name: ceph-source-binding
spec:
source:
ref:
kind: Kamelet
apiVersion: camel.apache.org/v1alpha1
name: ceph-source
properties:
accessKey: "The Access Key"
bucketName: "The Bucket Name"
cephUrl: "http://ceph-storage-address.com"
secretKey: "The Secret Key"
zoneGroup: "The Bucket Zone Group"
sink:
ref:
kind: Channel
apiVersion: messaging.knative.dev/v1
name: mychannel
22.3.1.1. Prerequisite
Make sure you have "Red Hat Integration - Camel K" installed into the OpenShift cluster you’re connected to.
22.3.1.2. Procedure for using the cluster CLI
-
Save the
ceph-source-binding.yamlfile to your local drive, and then edit it as needed for your configuration. Run the source by using the following command:
oc apply -f ceph-source-binding.yaml
22.3.1.3. Procedure for using the Kamel CLI
Configure and run the source by using the following command:
kamel bind ceph-source -p "source.accessKey=The Access Key" -p "source.bucketName=The Bucket Name" -p "source.cephUrl=http://ceph-storage-address.com" -p "source.secretKey=The Secret Key" -p "source.zoneGroup=The Bucket Zone Group" channel:mychannel
This command creates the KameletBinding in the current namespace on the cluster.
22.3.2. Kafka Source
You can use the ceph-source Kamelet as a Kafka source by binding it to a Kafka topic.
ceph-source-binding.yaml
apiVersion: camel.apache.org/v1alpha1
kind: KameletBinding
metadata:
name: ceph-source-binding
spec:
source:
ref:
kind: Kamelet
apiVersion: camel.apache.org/v1alpha1
name: ceph-source
properties:
accessKey: "The Access Key"
bucketName: "The Bucket Name"
cephUrl: "http://ceph-storage-address.com"
secretKey: "The Secret Key"
zoneGroup: "The Bucket Zone Group"
sink:
ref:
kind: KafkaTopic
apiVersion: kafka.strimzi.io/v1beta1
name: my-topic
22.3.2.1. 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.
22.3.2.2. Procedure for using the cluster CLI
-
Save the
ceph-source-binding.yamlfile to your local drive, and then edit it as needed for your configuration. Run the source by using the following command:
oc apply -f ceph-source-binding.yaml
22.3.2.3. Procedure for using the Kamel CLI
Configure and run the source by using the following command:
kamel bind ceph-source -p "source.accessKey=The Access Key" -p "source.bucketName=The Bucket Name" -p "source.cephUrl=http://ceph-storage-address.com" -p "source.secretKey=The Secret Key" -p "source.zoneGroup=The Bucket Zone Group" kafka.strimzi.io/v1beta1:KafkaTopic:my-topic
This command creates the KameletBinding in the current namespace on the cluster.
