This example demonstrates how you can use Apache Camel with Spring Boot based on a fabric8 Java base image.
The quickstart uses Spring Boot to configure a little application that includes a Camel route that triggers a message every 5th second, and routes the message to a log.
You need nexus installed into nexus project see
The example can be built with
mvn clean install
The example can be run locally using the following Maven goal:
mvn spring-boot:run
It is assumed a running Kubernetes platform is already running. If not you can find details how to get started.
Assuming your current shell is connected to Kubernetes or OpenShift so that you can type a command like
kubectl get pods
or for OpenShift
oc get pods
Then the following command will package your app and run it on Kubernetes:
mvn fabric8:run
To list all the running pods:
oc get pods
Then find the name of the pod that runs this quickstart, and output the logs from the running pods with:
oc logs <name of pod>
You can also use the fabric8 developer console to manage the running pods, and view logs and much more.
You can find more details about running this quickstart on the website. This also includes instructions how to change the Docker image user and registry.

Ansible Operator based deployment
Build application image:
-- build image in openshift namespace for now
mvn package
oc -n openshift new-build --binary --name=spring-boot-camel -l app=spring-boot-camel -i fuse7-java-openshift:1.2
oc -n openshift start-build spring-boot-camel --from-file=./target/helloservice-1.0-SNAPSHOT.jar --follow
The application ansible role is here:
https://github.com/eformat/spring-boot-camel-role.git
Build the operator image
cd spring-boot-camel/operator/spring-boot-camel-operator
podman build --no-cache -t spring-boot-camel-operator:v0.0.1 -f build/Dockerfile .
Setup podman locally
HOST=$(oc get route default-route -n openshift-image-registry --template='{{ .spec.host }}')
sudo mkdir -p /etc/containers/certs.d/$HOST
echo $(oc get secrets router-ca --template='{{index .data "tls.crt"}}' -n openshift-ingress-operator) | base64 -d | sudo tee /etc/containers/certs.d/$HOST/ca.crt
podman login -u $(oc whoami) -p $(oc whoami -t) $HOST
Deploy operator image
oc new-project spring-boot-camel
oc policy add-role-to-user view system:serviceaccount:$(oc project -q):default
--
podman tag localhost/spring-boot-camel-operator:v0.0.1 $HOST/spring-boot-camel/spring-boot-camel-operator:v0.0.1
podman login -u $(oc whoami) -p $(oc whoami -t) $HOST
podman push $HOST/spring-boot-camel/spring-boot-camel-operator:v0.0.1
Create CR, CRD, Kube objects (admin privilege)
oc apply -f deploy/crds/springbootcamel_v1alpha1_springbootcamel_crd.yaml
oc apply -f deploy/service_account.yaml
oc apply -f deploy/role.yaml
oc apply -f deploy/role_binding.yaml
oc apply -f deploy/operator.yaml
Create CR - Application (adjust values to suit)
oc apply -f deploy/crds/springbootcamel_v1alpha1_springbootcamel_cr.yaml
Delete Application
oc delete -f deploy/crds/springbootcamel_v1alpha1_springbootcamel_cr.yaml
-- OR
oc delete SpringBootCamel/spring-boot-camel
Delete operator and configs
oc delete -f deploy/operator.yaml
oc delete -f deploy/service_account.yaml
oc delete -f deploy/role.yaml
oc delete -f deploy/role_binding.yaml
