Quarkus demo: AWS S3 Client

This example showcases how to use the AWS S3 client with Quarkus. As a prerequisite install AWS Command line interface.

Run the demo in dev mode

  • Run ./mvnw clean package and then java -jar ./target/quarkus-app/quarkus-run.jar
  • In dev mode ./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.

Running in native (using localstack)

S3 local instance

Start localstack: docker run --rm --name local-s3 -p 8008:4566 -e SERVICES=s3 -e EAGER_SERVICE_LOADING=1 -e START_WEB=0 -d localstack/localstack

S3 listens on localhost:8008 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 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:8008

You can compile the application into a native executable using:

./mvnw clean package -Pnative

and run with:

AWS_PROFILE=localstack ./target/amazon-s3-quickstart-1.0.0-SNAPSHOT-runner -Dquarkus.s3.endpoint-override=http://localhost:8008 -Dquarkus.s3.path-style-access=true

Running native in container (using localstack)

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-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 --network=localstack --name localstack -p 8008:4566 -e SERVICES=s3 -e EAGER_SERVICE_LOADING=1 -e START_WEB=0 -d 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:8008

Run quickstart container connected to that network (note that we're using internal port of the S3 localstack) docker run -i --rm --network=localstack -p 8080:8080 -e quarkus.s3.endpoint-override=http://localstack:4566 -e quarkus.s3.path-style-access=true -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 quarkus/amazon-s3-quickstart

Go to http://localhost:8080/s3.html or http://localhost:8080/async-s3.html

Clean up your environment docker stop localstack

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 using your default AWS profile aws s3 mb s3://quarkus.s3.quickstart.11.22.33

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

Run demo

You can run the demo the same way as for a local instance, but you need to change the application.properties.

  • remove or comment out quarkus.s3.endpoint-override - as you are going to communicate with the AWS service now
  • remove or comment out quarkus.s3.aws.region - region is going to be retrieved via the default providers chain in the following order:
    • aws.region system property
    • region property from the profile file
  • remove or comment out quarkus.s3.aws.credentials.type - if not configured the client uses default credentials provider chain that looks for credentials in this order:
    • Java System Properties - aws.accessKeyId and aws.secretKey
    • Environment Variables - AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY
    • Credential profiles file at the default location (~/.aws/credentials) shared by all AWS SDKs and the AWS CLI

Build the application

./mvnw clean package

And then run it

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

Or, build as native executable

./mvnw clean package -Pnative

And then run it

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