Quarkus Apache Camel-K

In a nutshell, apache camel-k is:

Apache Camel-K  = Apache Camel + K8s

Apache camel-k provides powerful integration pattern along with serverless capabilities on k8s. Quarkus is a full-stack, k8s-native, Java Application Framework tailored for OpenJDK HotSpot and GraalVM. As compared, to other frameworks, such as Spring, it offers small memory footprint and reduced boot time. It supports combination of both imperative code and non-blocking reactive style.

In this blog, I will build classical account service using quarkus + camel-k

Possible area where apache camel-k and quarkus can help:

• serving machine leaning model
• build rapid fire micro-services
• kafka connector
• EIS pattern
• ..more..

Pre-requisite

• k3d (micro k8s)
• apache camel-k on k8s

    kamel install --registry docker.io --organization <username> --registry-auth-username <username> --registry-auth-password <password>
  

• kamel cli

Play time

• Run by using following command:

kamel run --name account --dev \
   src/main/java/com/gonnect/quarkus/accounts/AccountRoute.java \
   --save

• verify below logs:

• port forward port 80 to 8081 and issue the following curl command:

   curl http://localhost:8081/account

NOTE:

In the background, Apache Camel K creates the CRD Integration, which can viewed using following command:

kubectl get integration account -o yaml
