= image:kamelets/dns-dig-action.svg[] DNS DIG Action

*Provided by: "Apache Software Foundation"*

*Support Level for this Kamelet is: "Preview"*

Query a DNS through Dig

The Kamelet expects the following headers to be set:

- `domain-name` / `ce-domain-name`: as the domain for which we are querying the DNS

- `dns-type` / `ce-dns-type`: as the DNS type

If the domain-name header won't be set the body will be used as domain name.

If the dns-type header won't be set, the DNS Type A will be used.

== Configuration Options

The Kamelet does not specify any configuration option.

== Usage

This section summarizes how the `dns-dig-action` can be used in various contexts.

=== Knative Action

The `dns-dig-action` Kamelet can be used as intermediate step in a Knative binding.

[source,yaml]
----
apiVersion: camel.apache.org/v1alpha1
kind: KameletBinding
metadata:
  name: dns-dig-action-binding
spec:
  source:
    ref:
      kind: Kamelet
      apiVersion: camel.apache.org/v1alpha1
      name: timer-source
    properties:
      message: "Hello"
  steps:

----
Make sure you have xref:latest@camel-k::installation/installation.adoc[Camel K installed] into the Kubernetes cluster you're connected to.

Save the `dns-dig-action-binding.yaml` file into your hard drive, then configure it according to your needs.

You can run the action using the following command:

[source,shell]
----
kubectl apply -f dns-dig-action-binding.yaml
----

==== *Dependencies*

The Kamelet needs the following dependencies:


- camel:dns

- 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:

[source,shell]
----
kamel bind timer-source?message=Hello --step dns-dig-action channel/mychannel
----

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

=== Kafka Action

The `dns-dig-action` Kamelet can be used as intermediate step in a Kafka binding.

.dns-dig-action-binding.yaml
[source,yaml]
----
apiVersion: camel.apache.org/v1alpha1
kind: KameletBinding
metadata:
  name: dns-dig-action-binding
spec:
  source:
    ref:
      kind: Kamelet
      apiVersion: camel.apache.org/v1alpha1
      name: timer-source
    properties:
      message: "Hello"
  steps:
  - ref:
      kind: Kamelet
      apiVersion: camel.apache.org/v1alpha1
      name: dns-dig-action
  sink:
    ref:
      kind: KafkaTopic
      apiVersion: kafka.strimzi.io/v1beta1
      name: my-topic

----

Ensure that you've installed https://strimzi.io/[Strimzi] and created a topic named `my-topic` in the current namespace.
Make also sure you have xref:latest@camel-k::installation/installation.adoc[Camel K installed] into the Kubernetes cluster you're connected to.

Save the `dns-dig-action-binding.yaml` file into your hard drive, then configure it according to your needs.

You can run the action using the following command:

[source,shell]
----
kubectl apply -f dns-dig-action-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:

[source,shell]
----
kamel bind timer-source?message=Hello --step dns-dig-action 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.
