Usage

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

Knative Source

The google-calendar-source Kamelet can be used as Knative source by binding it to a Knative object.

google-calendar-source-binding.yaml
apiVersion: camel.apache.org/v1alpha1
kind: KameletBinding
metadata:
  name: google-calendar-source-binding
spec:
  source:
    ref:
      kind: Kamelet
      apiVersion: camel.apache.org/v1alpha1
      name: google-calendar-source
    properties:
      accessToken: "The Access Token"
      applicationName: "The Application name"
      calendarId: "The Calendar ID"
      clientId: "The Client Id"
      clientSecret: "The Client Secret"
      index: "The Index"
      refreshToken: "The Refresh Token"
  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 google-calendar-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 google-calendar-source-binding.yaml

Dependencies

The Kamelet needs the following dependencies:

  • camel:jackson

  • camel:google-calendar

  • 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 google-calendar-source -p "source.accessToken=The Access Token" -p "source.applicationName=The Application name" -p "source.calendarId=The Calendar ID" -p "source.clientId=The Client Id" -p "source.clientSecret=The Client Secret" -p "source.index=The Index" -p "source.refreshToken=The Refresh Token" channel:mychannel

This will create the KameletBinding under the hood and apply it to the current namespace in the cluster.

Kafka Source

The google-calendar-source Kamelet can be used as Kafka source by binding it to a Kafka topic.

google-calendar-source-binding.yaml
apiVersion: camel.apache.org/v1alpha1
kind: KameletBinding
metadata:
  name: google-calendar-source-binding
spec:
  source:
    ref:
      kind: Kamelet
      apiVersion: camel.apache.org/v1alpha1
      name: google-calendar-source
    properties:
      accessToken: "The Access Token"
      applicationName: "The Application name"
      calendarId: "The Calendar ID"
      clientId: "The Client Id"
      clientSecret: "The Client Secret"
      index: "The Index"
      refreshToken: "The Refresh Token"
  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 google-calendar-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 google-calendar-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 google-calendar-source -p "source.accessToken=The Access Token" -p "source.applicationName=The Application name" -p "source.calendarId=The Calendar ID" -p "source.clientId=The Client Id" -p "source.clientSecret=The Client Secret" -p "source.index=The Index" -p "source.refreshToken=The Refresh Token" 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.
