25.3. Usage

This section describes how you can use the ftp-source.

25.3.1. Knative Source

You can use the ftp-source Kamelet as a Knative source by binding it to a Knative object.

ftp-source-binding.yaml

apiVersion: camel.apache.org/v1alpha1
kind: KameletBinding
metadata:
  name: ftp-source-binding
spec:
  source:
    ref:
      kind: Kamelet
      apiVersion: camel.apache.org/v1alpha1
      name: ftp-source
    properties:
      connectionHost: "The Connection Host"
      directoryName: "The Directory Name"
      password: "The Password"
      username: "The Username"
  sink:
    ref:
      kind: Channel
      apiVersion: messaging.knative.dev/v1
      name: mychannel

25.3.1.1. Prerequisite

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

25.3.1.2. Procedure for using the cluster CLI

Save the ftp-source-binding.yaml file to your local drive, and then edit it as needed for your configuration.
Run the source by using the following command:
```
oc apply -f ftp-source-binding.yaml
```

25.3.1.3. Procedure for using the Kamel CLI

Configure and run the source by using the following command:

kamel bind ftp-source -p "source.connectionHost=The Connection Host" -p "source.directoryName=The Directory Name" -p "source.password=The Password" -p "source.username=The Username" channel:mychannel

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

25.3.2. Kafka Source

You can use the ftp-source Kamelet as a Kafka source by binding it to a Kafka topic.

ftp-source-binding.yaml

apiVersion: camel.apache.org/v1alpha1
kind: KameletBinding
metadata:
  name: ftp-source-binding
spec:
  source:
    ref:
      kind: Kamelet
      apiVersion: camel.apache.org/v1alpha1
      name: ftp-source
    properties:
      connectionHost: "The Connection Host"
      directoryName: "The Directory Name"
      password: "The Password"
      username: "The Username"
  sink:
    ref:
      kind: KafkaTopic
      apiVersion: kafka.strimzi.io/v1beta1
      name: my-topic

25.3.2.1. 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.

25.3.2.2. Procedure for using the cluster CLI

Save the ftp-source-binding.yaml file to your local drive, and then edit it as needed for your configuration.
Run the source by using the following command:
```
oc apply -f ftp-source-binding.yaml
```

25.3.2.3. Procedure for using the Kamel CLI

Configure and run the source by using the following command:

kamel bind ftp-source -p "source.connectionHost=The Connection Host" -p "source.directoryName=The Directory Name" -p "source.password=The Password" -p "source.username=The Username" kafka.strimzi.io/v1beta1:KafkaTopic:my-topic

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