Quarkus demo: SQS Client

This example showcases how to use the AWS SQS client with Quarkus. As a prerequisite install Install AWS Command line interface.

AWS SQS local instance

Just run it as follows in order to start SQS locally: docker run --rm --name local-sqs 8010:4576 -e SERVICES=sqs -e START_WEB=0 -d localstack/localstack:0.11.1 SQS listens on localhost:8010 for REST endpoints.

Create an AWS profile for your local instance using AWS CLI:

$ aws configure --profile localstack
AWS Access Key ID [None]: test-key
AWS Secret Access Key [None]: test-secret
Default region name [None]: us-east-1
Default output format [None]:

Create SQS queue

Create a SQS queue and store Queue url in environment variable as we will need to provide it to the our app

$> QUEUE_URL=`aws sqs create-queue --queue-name=ColliderQueue --profile localstack --endpoint-url=http://localhost:8010`

Run the demo on dev mode

  • Run ./mvnw clean package and then java -Dqueue.url=$QUEUE_URL -jar ./target/amazon-sqs-quickstart-1.0-SNAPSHOT-runner.jar
  • In dev mode ./mvnw clean quarkus:dev -Dqueue.url=$QUEUE_URL

Send messages to the queue

Shoot with a couple of quarks

curl -XPOST -H"Content-type: application/json" http://localhost:8080/sync/cannon/shoot -d'{"flavor": "Charm", "spin": "1/2"}'
curl -XPOST -H"Content-type: application/json" http://localhost:8080/sync/cannon/shoot -d'{"flavor": "Strange", "spin": "1/2"}'

And receive it from the queue

curl http://localhost:8080/sync/cannon/shoot

Repeat the same using async endpoints

curl -XPOST -H"Content-type: application/json" http://localhost:8080/async/cannon/shoot -d'{"flavor": "Charm", "spin": "1/2"}'
curl -XPOST -H"Content-type: application/json" http://localhost:8080/async/cannon/shoot -d'{"flavor": "Strange", "spin": "1/2"}'

And receive it from the queue

curl http://localhost:8080/async/cannon/shoot

Running in native

You can compile the application into a native binary using:

./mvnw clean install -Pnative

and run with:

./target/amazon-sqs-quickstart-1.0-SNAPSHOT-runner

Running native in container

Build a native image in container by running: ./mvnw package -Pnative -Dnative-image.docker-build=true

Build a docker image: docker build -f src/main/docker/Dockerfile.native -t quarkus/amazon-sqs-quickstart .

Create a network that connect your container with localstack docker network create localstack

Stop your localstack container you started at the beginning docker stop local-sqs

Start localstack and connect to the network docker run --rm --network=localstack --name localstack -p 8010:4576 -e SERVICES=sqs -e START_WEB=0 -d localstack/localstack:0.11.1

Create queue

$> QUEUE_URL=`aws sqs create-queue --queue-name=ColliderQueue --profile localstack --endpoint-url=http://localhost:8010`

Run quickstart container connected to that network (note that we're using internal port of the localstack) docker run -i --rm --network=localstack -p 8080:8080 quarkus/amazon-sqs-quickstart -Dquarkus.sqs.endpoint-override=http://localstack:4576

Send messsage

curl -XPOST -H"Content-type: application/json" http://localhost:8080/sync/cannon/shoot -d'{"flavor": "Charm", "spin": "1/2"}'

Receive message

curl http://localhost:8080/sync/cannon/shoot
