DNS IP Action

Provided by: "Apache Software Foundation"

Support Level for this Kamelet is: "Stable"

Get an IP from a DNS

The Kamelet expects the following headers to be set:

domain / ce-domain: as the domain for which we are looking for the IP

If the header won’t be set the body will be used as domain to look for.

Configuration Options

The dns-ip-action Kamelet does not specify any configuration options.

Dependencies

At runtime, the dns-ip-action Kamelet relies upon the presence of the following dependencies:

camel:core
camel:dns
camel:kamelet

Camel JBang usage

Prerequisites

You’ve installed JBang.
You have executed the following command:

jbang app install camel@apache/camel

Supposing you have a file named route.yaml with this content:

- route:
    from:
      uri: "kamelet:timer-source"
      parameters:
        period: 10000
        message: 'test'
      steps:
        - to:
            uri: "kamelet:log-sink"

You can now run it directly through the following command

camel run route.yaml
