Quarkus demo: Amazon S3 Client

This example showcases how to use the AWS S3 client with Quarkus.

Run the Demo in Dev Mode

  • Run ./mvnw clean quarkus:dev

Go to http://localhost:8080/s3.html, it should show a simple App to manage files on your Bucket. You can upload files to the bucket via the form.

Alternatively, go to http://localhost:8080/async-s3.html with the simple App communicating with Async resources.

Using LocalStack

As a prerequisite, install the AWS Command Line Interface.

Start LocalStack:

docker run \
 --rm \
 --name local-s3 \
 -p 4566:4566 \
 locals

S3 listens on `localhost:4566` for REST endpoints.

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

```sh
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 bucket

Create a S3 bucket using AWS CLI and the localstack profile.

aws s3 mb s3://quarkus.s3.quickstart --profile localstack --endpoint-url=http://localhost:4566`

Run the demo

You can compile the application and run it with:

./mvnw install
AWS_PROFILE=localstack java -Dquarkus.s3.endpoint-override=http://localhost:4566 -jar ./target/quarkus-app/quarkus-run.jar

Go to http://localhost:8080/s3.html or http://localhost:8080/async-s3.html, to test the application.

Running in native

You can compile the application into a native executable using:

./mvnw install -Dnative

And run it with:

AWS_PROFILE=localstack ./target/amazon-s3-quickstart-1.0.0-SNAPSHOT-runner -Dquarkus.s3.endpoint-override=http://localhost:4566

Running native in container

Build a native image in a container by running:

./mvnw install -Dnative -DskipTests -Dquarkus.native.container-build=true

Build a Docker image:

docker build -f src/main/docker/Dockerfile.native -t quarkus/amazon-s3-quickstart .

Create a network that connects your container with LocalStack:

docker network create localstack

Stop your LocalStack container you started at the beginning:

docker stop local-s3

Start LocalStack and connect to the network:

docker run \
  --rm \
  --name local-s3 \
  --network=localstack \
  -p 4566:4566 \
  localstack/localstack

Create a S3 bucket using AWS CLI and the localstack profile.

aws s3 mb s3://quarkus.s3.quickstart --profile localstack --endpoint-url=http://localhost:4566`

Run the Quickstart container connected to that network (note that we're using the internal port of the LocalStack container):

docker run -i --rm --network=localstack \
  -p 8080:8080 \
  -e QUARKUS_S3_ENDPOINT_OVERRIDE="http://local-s3:4566" \
  -e QUARKUS_S3_AWS_REGION="us-east-1" \
  -e QUARKUS_S3_AWS_CREDENTIALS_TYPE="static" \
  -e QUARKUS_S3_AWS_CREDENTIALS_STATIC_PROVIDER_ACCESS_KEY_ID="test-key" \
  -e QUARKUS_S3_AWS_CREDENTIALS_STATIC_PROVIDER_SECRET_ACCESS_KEY="test-secret" \
  -e QUARKUS_S3_PATH_STYLE_ACCESS="true" \
  quarkus/amazon-s3-quickstart

Go to http://localhost:8080/s3.html or http://localhost:8080/async-s3.html, to test the application.

Clean up your environment:

docker stop local-s3
docker network rm localstack

Using AWS account

Before you can use the AWS SDKs with S3, you must get an AWS access key ID and secret access key. For more information, see:

Create a S3 bucket using AWS CLI and the localstack profile.

aws s3 mb s3://quarkus.s3.12.345.99`

NOTE: Please assure the bucket name you created is unique across AWS S3 and update . See Amazon S3 Bucket Naming Requirements

Run demo

You can run the demo the same way as for a local instance, but you don't need to override the endpoint as you are going to communicate with the AWS service with the default AWS profile.

Run it:

java -Dbucket.name=quarkus.s3.12.345.99 -jar ./target/quarkus-app/quarkus-run.jar

Or, run it natively:

./target/amazon-s3-quickstart-1.0.0-SNAPSHOT-runner -Dbucket.name=quarkus.s3.12.345.99
