Usage

This section summarizes how the ftp-source can be used in various contexts.

Knative Source

The ftp-source Kamelet can be used as 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

Make sure you have Camel K installed into the Kubernetes cluster you’re connected to.

Save the ftp-source-binding.yaml file into your hard drive, then configure it according to your needs.

You can run the source using the following command:

kubectl apply -f ftp-source-binding.yaml

Dependencies

The Kamelet needs the following dependencies:

  • camel:ftp

  • camel:core

  • camel:kamelet

Binding to Knative using the Kamel CLI:

The procedure described above can be simplified into a single execution of the kamel bind 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 will create the KameletBinding under the hood and apply it to the current namespace in the cluster.

Kafka Source

The ftp-source Kamelet can be used as 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

Ensure that you’ve installed Strimzi and created a topic named my-topic in the current namespace. Make also sure you have Camel K installed into the Kubernetes cluster you’re connected to.

Save the ftp-source-binding.yaml file into your hard drive, then configure it according to your needs.

You can run the source using the following command:

kubectl apply -f ftp-source-binding.yaml

Binding to Kafka using the Kamel CLI:

The procedure described above can be simplified into a single execution of the kamel bind 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 will create the KameletBinding under the hood and apply it to the current namespace in the cluster.
