  • mvn:org.apache.camel.kamelets:camel-kamelets-utils:4.8.0

  • camel:core

  • camel:kafka

  • 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:kafka-batch-ssl-source"
      parameters:
        .
        .

      steps:
        - to:
            uri: "kamelet:log-sink"

You can now run it directly through the following command

camel run route.yaml
