lamp service

This repository contains the scaffolding for a Dropwizard-based Java-Service. The goal of this repository is to provide a minimal running version that can be used with the infrastructure in the lamp-infrastructure Repository.

Building

Using maven

1. Run mvn clean package to build your application

Using Docker

Ensure Docker is installed. https://docs.docker.com/get-docker/

1. Run ./build.sh to build your application

Start the application

Run java -jar target/dropwizard-example-1.0-SNAPSHOT.jar server config.yml

Calling the service

Once the service is up you can call the root endpoint at port 8080: curl localhost:8080

Configuration

The servers http port can be set via the env var APP_PORT.

You can for example start the application exposing port 9090 like this: APP_PORT=9090 java -jar target/dropwizard-example-1.0-SNAPSHOT.jar server config.yml

Accessing the service after deployment to AKS

The provided service is accessible through public IP. The IP is provisioned through an Azure load balancer. The health check can be accessed like this:

export SERVICE_IP=$(kubectl get ingress lamp-http -n lamp -o jsonpath={.status.loadBalancer.ingress[0].ip})
curl http://${SERVICE_IP}/admin/healthcheck
