Simple Netflix Eureka client using Quarkus

otaibe.org - Simple Netflix Eureka client using Quarkus

Bare minimum Eureka client functionality in order to work with Netflix Eureka Server

Additional info

The Quarkus Based Eureka Client is rewritten as a library in otaibe-commons-quarkus project . In that way it is easier to plug it in into existing project. Some basic Actuators endpoints are also added there.

In this project you can check the implementation of the Quarkus Based Eureka Client with some additional Actuator Endpoints like /metrics, /info and /health. The endpoints are related to the quarkus.servlet.context-path property.

Some tips

• Use org.otaibe.eureka.client.service.EurekaClient.getNextServer to retrieve the next registered instance.
• You can use the Prebuild Eureka Docker Image
• Image is listen on 24455 and is with enableSelfPreservation set to false by default.
• You can start the image with:

docker run -i --rm -p 24455:24455 triphon/otaibe-nginx-with-eureka-demo-eureka-server

Start and build

• Build native applicaiton with: mvn clean package -Pnative -Dquarkus.native.container-build=true
• Package the docker image: docker build -f src/main/docker/Dockerfile.native -t triphon/org-otaibe-eureka-client .
• Run the Prebuild Eureka Docker Image

docker run -i --rm -p 24455:24455 triphon/otaibe-nginx-with-eureka-demo-eureka-server

• Start the native application (does not forget to change the __HOST_NAME_OR_IP__ with the correct value):

docker run -i --rm -p 9888:9888 \
    --env "EUREKA_INSTANCE_HOSTNAME=__HOST_NAME_OR_IP__" \
    triphon/org-otaibe-eureka-client

• If you want to connect to other Eureka server the command should be (adjust __EUREKA_HOST_PORT__ too):

docker run -i --rm -p 9888:9888 \
    --env "EUREKA_INSTANCE_HOSTNAME=__HOST_NAME_OR_IP__" \
    --env "EUREKA_CLIENT_SERVICEURL_DEFAULTZONE=http://__EUREKA_HOST_PORT__/eureka/" \
    triphon/org-otaibe-eureka-client

• Review the app in the Eureka Frontend.
