Apache Camel K

Apache Camel K is a lightweight integration framework built from Apache Camel that runs natively on Kubernetes and is specifically designed for serverless and microservice architectures. The Camel K Kubernetes Operator is in charge to transform a user provided Integration custom resource into a Camel application running on the cloud.

Users of Camel K can instantly run integration code written in any Camel DSL without worrying about the building and deployment of the application on the cloud.

How It Works

Just write a helloworld.yaml integration file with the following content:

apiVersion: camel.apache.org/v1
kind: Integration
metadata:
  name: helloworld
spec:
  flows:
  - from:
      steps:
      - setBody:
          simple: Hello Camel from ${routeId}
      - log: ${body}
      uri: timer:yaml

You can then execute the following command:

kubectl -f helloworld.yaml

The integration code will immediately run in the cloud. Continue reading the documentation to install and get started with Camel K.

Camel dependencies matrix

This is a development version of Camel K. It should not be used in production.

From Camel K version 2 onward you will be able to use any Camel K Runtime. Each runtime depends on a Camel Quarkus, Camel and Quarkus Platform version. Every Camel K has a default runtime used, but you can pick any Camel K Runtime available (backward and forward compatible).
