How to deploy Podman images to OpenShift Container Platform (CRC on localhost)

I have a microservice on localhost and I want to deploy its Podman image on OCP, which I am running using CRC on localhost.

     

1.Get the image registry of ocp:

oc registry info

or

oc get route default-route -n openshift-image-registry

2.Create a is.yaml file

oc create -f is.yaml 

3.Tag podman image:

podman tag image_name `oc registry info`/project_name/image_name:latest

4.Authenticate podman

podman login `oc registry info` -u kubeadmin -p `oc whoami -t` --tls-verify=false

5.Push Podman image

podman push image_id `oc registry info`/project_name/image_name:latest --tls-verify=false

6.Create new app on OpenShift

oc new-app --docker-image=`oc registry info`/project_name/image_name:latest --name=new_app_name -l app=new_app_name

 

Apache Camel global exception handler

@Component
public class SchedRouteBuilder extends RouteBuilder {

    @Override
    public void configure() throws Exception {
        // Define a global exception handler
        onException(Exception.class)
                .process(new Processor() {
                    @Override
                    public void process(Exchange exchange) throws Exception {
                        Exception exception = exchange.getProperty(Exchange.EXCEPTION_CAUGHT, Exception.class);
                        exception.printStackTrace();
                    }
                })
                .handled(true);

        from("direct:message-producer")
                .to("paho-mqtt5:{{topicname}}?brokerUrl=tcp://{{brokeraddress}}:{{brokerport}}");
    }

}

Run minikube with podman on Fedora

After install minikube as described in the documentation, set rootless property to true to use Podman without sudo:

minikube config set rootless true

then start minikube with podman driver:

minikube start --driver=podman --container-runtime=containerd

minikube kubectl cluster-info
