camel-quarkus-jsonvalidation-api

Camel-Quarkus-JsonValidation-Api project

This project leverages Red Hat build of Quarkus 2.2.x, the Supersonic Subatomic Java Framework.

It exposes the following RESTful service endpoints using Apache Camel REST DSL and the Apache Camel Quarkus Platform HTTP extension:

/validateMembershipJSON : validates a sample Membership JSON instance through the POST HTTP method.
/openapi.json: returns the OpenAPI 3.0 specification for the service.
/q/health : returns the Camel Quarkus MicroProfile health checks
/q/metrics : the Camel Quarkus MicroProfile metrics

Prerequisites

JDK 11 installed with JAVA_HOME configured appropriately
Apache Maven 3.8.1+

OPTIONAL: Jaeger, a distributed tracing system for observability (open tracing). 💡 A simple way of starting a Jaeger tracing server is with docker or podman:

Start the Jaeger tracing server:

podman run --rm -e COLLECTOR_ZIPKIN_HOST_PORT=:9411 -e COLLECTOR_OTLP_ENABLED=true \
-p 6831:6831/udp -p 6832:6832/udp \
-p 5778:5778 -p 16686:16686 -p 4317:4317 -p 4318:4318 -p 14250:14250  -p 14268:14268 -p 14269:14269 -p 9411:9411 \
quay.io/jaegertracing/all-in-one:latest

While the server is running, browse to http://localhost:16686 to view tracing events.

Running the application in dev mode

You can run your application in dev mode that enables live coding using:

./mvnw quarkus:dev -Dquarkus.kubernetes-config.enabled=false

Packaging and running the application locally

The application can be packaged using:

./mvnw clean package

It produces the quarkus-run.jar file in the target/quarkus-app/ directory. Be aware that it’s not an über-jar as the dependencies are copied into the target/quarkus-app/lib/ directory.

The application is now runnable using:

java -Dquarkus.kubernetes-config.enabled=false -jar target/quarkus-app/quarkus-run.jar

If you want to build an über-jar, execute the following command:

./mvnw clean package -Dquarkus.package.type=uber-jar

The application, packaged as an über-jar, is now runnable using:

java -Dquarkus.kubernetes-config.enabled=false -jar target/camel-quarkus-jsonvalidation-api-1.0.0-runner.jar

According to your environment, you may want to customize the Jaeger collector endpoint by adding the following run-time system properties:

quarkus.opentelemetry.tracer.exporter.otlp.endpoint

Example:

java -Dquarkus.kubernetes-config.enabled=false -Dquarkus.opentelemetry.tracer.exporter.otlp.endpoint="http://localhost:4317" -jar target/quarkus-app/quarkus-run.jar

Packaging and running the application on Red Hat OpenShift

Pre-requisites

Access to a Red Hat OpenShift cluster v3 or v4
User has self-provisioner privilege or has access to a working OpenShift project

Login to the OpenShift cluster
```
oc login ...
```

Create an OpenShift project or use your existing OpenShift project. For instance, to create camel-quarkus

oc new-project ceq-services-jvm --display-name="Red Hat build of Apache Camel for Quarkus Apps - JVM Mode"

Create an allInOne Jaeger instance.

IF NOT ALREADY INSTALLED:

Install, via OLM, the Red Hat OpenShift distributed tracing platform (Jaeger) operator with an AllNamespaces scope. ⚠️ Needs cluster-admin privileges

oc create --save-config -f - <<EOF
apiVersion: operators.coreos.com/v1alpha1
kind: Subscription
metadata:
    name: jaeger-product
    namespace: openshift-operators
spec:
    channel: stable
    installPlanApproval: Automatic
    name: jaeger-product
    source: redhat-operators
    sourceNamespace: openshift-marketplace
EOF

Verify the successful installation of the Red Hat OpenShift distributed tracing platform operator
```
watch oc get sub,csv
```

Create the allInOne Jaeger instance.

oc create --save-config -f - <<EOF
apiVersion: jaegertracing.io/v1
kind: Jaeger
metadata:
    name: jaeger-all-in-one-inmemory
spec:
    allInOne:
        options:
        log-level: info
    strategy: allInOne
EOF

Create the quarkus-opentracing-endpoint-secret containing the QUARKUS OPENTRACING endpoint configuration options. These options are leveraged by the Camel Quarkus Opentracing extension to connect to the jaeger collector. Adapt the quarkus.jaeger.endpointaccording to your environment.

⚠️ Replace jaeger endpoint according to your environment
```
oc create secret generic quarkus-opentracing-endpoint-secret \
--from-literal=quarkus.jaeger.endpoint="http://jaeger-all-in-one-inmemory-collector.ceq-services-jvm.svc:14268/api/traces"
```
Use either the S2I binary workflow or S2I source workflow to deploy the camel-quarkus-jsonvalidation-api app as described below.

OpenShift S2I binary workflow

This leverages the Quarkus OpenShift extension and is only recommended for development and testing purposes.

Creating a native executable

Running locally

You can create a native executable using: ./mvnw package -Pnative.

Or, if you don't have GraalVM installed, you can run the native executable build in a container using: ./mvnw package -Pnative -Dquarkus.native.container-build=true.

You can then execute your native executable with: ./target/camel-quarkus-jsonvalidation-api-1.0.0-runner

If you want to learn more about building native executables, please consult https://quarkus.io/guides/building-native-image.

Deploying the native executable as an OpenShift Serverless service

Prerequisites

Access to a Red Hat OpenShift 4 cluster
- OpenShift Serverless operator is installed
- OpenShift Knative Serving is installed
Podman or Docker container-runtime environment for native compilation
The kn CLI tool is installed
User has self-provisioner privilege or has access to a working OpenShift project

Instructions

Login to the OpenShift cluster
```
oc login ...
```
Create an OpenShift project or use your existing OpenShift project. For instance, to create ceq-services-native
```
oc new-project ceq-services-native --display-name="Red Hat build of Apache Camel for Quarkus - Native Mode"
```

Build a Linux executable using a container build. Compiling a Quarkus application to a native executable consumes a lot of memory during analysis and optimization. You can limit the amount of memory used during native compilation by setting the quarkus.native.native-image-xmx configuration property. Setting low memory limits might increase the build time.

For Docker use:

./mvnw package -Pnative -Dquarkus.native.container-build=true \
-Dquarkus.native.native-image-xmx=6g

For Podman use:

./mvnw package -Pnative -Dquarkus.native.container-build=true \
-Dquarkus.native.container-runtime=podman \
-Dquarkus.native.native-image-xmx=6g

Create the camel-quarkus-jsonvalidation-api container image using the OpenShift Docker build strategy. This strategy creates a container using a build configuration in the cluster.

Create a build config based on the src/main/docker/Dockerfile.native file:

cat src/main/docker/Dockerfile.native | oc new-build \
--name camel-quarkus-jsonvalidation-api --strategy=docker --dockerfile -

Build the project:

oc start-build camel-quarkus-jsonvalidation-api --from-dir . -F
