Amazon S3 Client

Amazon S3 is an object storage service. It can be employed to store any type of object which allows for uses like storage for Internet applications, backup and recovery, disaster recovery, data archives, data lakes for analytics, any hybrid cloud storage. This extension provides functionality that allows the client to communicate with the service when running in Quarkus. You can find more information about S3 at the Amazon S3 website.

The S3 extension is based on AWS Java SDK 2.x. It’s a major rewrite of the 1.x code base that offers two programming models (Blocking & Async).

The Quarkus extension supports two programming models:

  • Blocking access using URL Connection HTTP client (by default) or the Apache HTTP Client

  • Asynchronous programming based on JDK’s CompletableFuture objects and the Netty HTTP client (by default) or the AWS CRT-based HTTP client

In this guide, we see how you can get your REST services to use S3 locally and on AWS.

Prerequisites

To complete this guide, you need:

  • JDK 17+ installed with JAVA_HOME configured appropriately

  • an IDE

  • Apache Maven 3.8.1+

  • AWS Command line interface

  • An AWS Account to access the S3 service. Before you can use the AWS SDKs with Amazon S3, you must get an AWS access key ID and secret access key.

  • Optionally, Docker for your system to run S3 locally for testing purposes

Provision S3 locally via Dev Services

The easiest way to start working with S3 is to run a local instance using Dev Services.

You can optionally configure the buckets that are created on startup with the quarkus.s3.devservices.buckets config property.

Provision S3 locally manually

You can also setup a local version of S3 manually, first start a LocalStack container:

docker run -it --publish 4566:4566 -e SERVICES=s3 -e START_WEB=0 localstack/localstack:3.7.2

This starts a S3 instance that is accessible on port 4566.

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 a S3 bucket

Create a S3 bucket using AWS CLI

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

Solution

The application built here allows to manage files stored in Amazon S3.

We recommend that you follow the instructions in the next sections and create the application step by step. However, you can go right to the completed example.

Clone the Git repository: git clone https://github.com/quarkusio/quarkus-quickstarts.git, or download an archive.

The solution is located in the amazon-s3-quickstart directory.

Creating the Maven project

First, we need a new project. Create a new project with the following command:

mvn io.quarkus.platform:quarkus-maven-plugin:3.17.0:create \
    -DprojectGroupId=org.acme \
    -DprojectArtifactId=amazon-s3-quickstart \
    -DclassName="org.acme.s3.S3SyncClientResource" \
    -Dpath="/s3" \
    -Dextensions="resteasy-reactive-jackson,amazon-s3"
cd amazon-s3-quickstart

This command generates a Maven structure importing the RESTEasy Reactive/JAX-RS and S3 Client extensions. After this, the amazon-s3 extension has been added to your pom.xml.

The default setting for quarkus.http.limits.max-body-size is 10240K. This may limit your ability to upload multipart files larger than the default. If you want to upload larger files, you will need to set this limit explicitly.

Setting up the model

In this example, we will create an application to manage a list of files. The example application will demonstrate the two programming models supported by the extension.

Because the primary goal of our application is to upload a file into the S3 bucket, we need to setup the model we will be using to define the multipart/form-data payload, in the form of a @MultipartForm POJO.

Create a org.acme.s3.FormData class as follows:

package org.acme.s3;

import java.io.File;
import jakarta.ws.rs.core.MediaType;
import org.jboss.resteasy.reactive.PartType;
import org.jboss.resteasy.reactive.RestForm;

public class FormData {

    @RestForm("file")
    public File data;

    @RestForm
    @PartType(MediaType.TEXT_PLAIN)
    public String filename;

    @RestForm
    @PartType(MediaType.TEXT_PLAIN)
    public String mimetype;

}

The class defines three fields:

  • data that fill capture stream of uploaded bytes from the client

  • fileName that captures a filename as provided by the submited form

  • mimeType content type of the uploaded file

In the second step let’s create a bean that will represent a file in a Amazon S3 bucket as follows:

package org.acme.s3;

import software.amazon.awssdk.services.s3.model.S3Object;

public class FileObject {
    private String objectKey;

    private Long size;

    public FileObject() {
    }

    public static FileObject from(S3Object s3Object) {
        FileObject file = new FileObject();
        if (s3Object != null) {
            file.setObjectKey(s3Object.key());
            file.setSize(s3Object.size());
        }
        return file;
    }

    public String getObjectKey() {
        return objectKey;
    }

    public Long getSize() {
        return size;
    }

    public FileObject setObjectKey(String objectKey) {
        this.objectKey = objectKey;
        return this;
    }

    public FileObject setSize(Long size) {
        this.size = size;
        return this;
    }
}

Nothing fancy. One important thing to note is that having a default constructor is required by the JSON serialization layer. The static from method creates a bean based on the S3Object object provided by the S3 client response when listing all the objects in a bucket.

Create JAX-RS resource

Now create a org.acme.s3.CommonResource that will consist of methods to prepare S3 request to get object from a S3 bucket, or to put file into a S3 bucket. Note a configuration property bucket.name is defined here as the request method required name of the S3 bucket.

package org.acme.s3;

import org.eclipse.microprofile.config.inject.ConfigProperty;

import software.amazon.awssdk.services.s3.model.GetObjectRequest;
import software.amazon.awssdk.services.s3.model.PutObjectRequest;

abstract public class CommonResource {

    @ConfigProperty(name = "bucket.name")
    String bucketName;

    protected PutObjectRequest buildPutRequest(FormData formData) {
        return PutObjectRequest.builder()
                .bucket(bucketName)
                .key(formData.filename)
                .contentType(formData.mimetype)
                .build();
    }

    protected GetObjectRequest buildGetRequest(String objectKey) {
        return GetObjectRequest.builder()
                .bucket(bucketName)
                .key(objectKey)
                .build();
    }

}

Then, create a org.acme.s3.S3SyncClientResource that will provides an API to upload/download files as well as to list all the files in a bucket.

package org.acme.s3;

import java.util.Comparator;
import java.util.List;
import java.util.stream.Collectors;

import jakarta.inject.Inject;
import jakarta.ws.rs.Consumes;
import jakarta.ws.rs.GET;

@Path("/s3")
public class S3SyncClientResource extends CommonResource {
    @Inject
    S3Client s3;

    @POST
    @Path("upload")
    @Consumes(MediaType.MULTIPART_FORM_DATA)
    public Response uploadFile(FormData formData) throws Exception {

        if (formData.filename == null || formData.filename.isEmpty()) {
            return Response.status(Status.BAD_REQUEST).build();
        }

        if (formData.mimetype == null || formData.mimetype.isEmpty()) {
            return Response.status(Status.BAD_REQUEST).build();
        }

        PutObjectResponse putResponse = s3.putObject(buildPutRequest(formData),
                RequestBody.fromFile(formData.data));
        if (putResponse != null) {
            return Response.ok().status(Status.CREATED).build();
        } else {
            return Response.serverError().build();
        }
    }

    @GET
    @Path("download/{objectKey}")
    @Produces(MediaType.APPLICATION_OCTET_STREAM)
    public Response downloadFile(String objectKey) {
        ResponseBytes<GetObjectResponse> objectBytes = s3.getObjectAsBytes(buildGetRequest(objectKey));
        Response.ResponseBuilder response = Response.ok(objectBytes.asByteArray());
        response.header("Content-Disposition", "attachment;filename=" + objectKey);
        response.header("Content-Type", objectBytes.response().contentType());
        return response.build();
    }

    @GET
    @Produces(MediaType.APPLICATION_JSON)
    public List<FileObject> listFiles() {
        ListObjectsRequest listRequest = ListObjectsRequest.builder().bucket(bucketName).build();

        //HEAD S3 objects to get metadata
        return s3.listObjects(listRequest).contents().stream()
                .map(FileObject::from)
                .sorted(Comparator.comparing(FileObject::getObjectKey))
                .collect(Collectors.toList());
    }
}

Configuring S3 clients

Both S3 clients (sync and async) are configurable via the application.properties file that can be provided in the src/main/resources directory.

You need to add to the classpath a proper implementation of the sync client. By default the extension uses the URL connection HTTP client, so add a URL connection client dependency to the pom.xml file: 
<dependency>
    <groupId>software.amazon.awssdk</groupId>
    <artifactId>url-connection-client</artifactId>
</dependency>

If you want to use the Apache HTTP client instead, configure it as follows:

quarkus.s3.sync-client.type=apache

And add following dependency to the application pom.xml:

<dependency>
    <groupId>software.amazon.awssdk</groupId>
    <artifactId>apache-client</artifactId>
</dependency>

If you want to use the AWS CRT-based HTTP client instead, configure it as follows:

quarkus.s3.sync-client.type=aws-crt

And add the following dependency to the application pom.xml:

<dependency>
    <groupId>software.amazon.awssdk</groupId>
    <artifactId>aws-crt-client</artifactId>
</dependency>

For asynchronous client refer to Going asynchronous for more information.

If you’re going to use a local S3 instance, configure it as follows:

quarkus.s3.endpoint-override=http://localhost:4566

quarkus.s3.aws.region=us-east-1
quarkus.s3.aws.credentials.type=static
quarkus.s3.aws.credentials.static-provider.access-key-id=test-key
quarkus.s3.aws.credentials.static-provider.secret-access-key=test-secret

bucket.name=quarkus.s3.quickstart

  • quarkus.s3.aws.region - It’s required by the client, but since you’re using a local S3 instance you can pick any valid AWS region.

  • quarkus.s3.aws.credentials.type - Set static credentials provider with any values for access-key-id and secret-access-key

  • quarkus.s3.endpoint-override - Override the S3 client to use a local instance instead of an AWS service

  • bucket.name - Name of the S3 bucket

If you want to work with an AWS account, you’d need to set it with:

bucket.name=<your-bucket-name>

quarkus.s3.aws.region=<YOUR_REGION>
quarkus.s3.aws.credentials.type=default

  • bucket.name - name of the S3 bucket on your AWS account.

  • quarkus.s3.aws.region you should set it to the region where your S3 bucket was created,

  • quarkus.s3.aws.credentials.type - use the default credentials provider chain that looks for credentials in this order:

    • Java System Properties - aws.accessKeyId and aws.secretAccessKey

    • 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

    • Credentials delivered through the Amazon ECS if the AWS_CONTAINER_CREDENTIALS_RELATIVE_URI environment variable is set and the security manager has permission to access the variable,

    • Instance profile credentials delivered through the Amazon EC2 metadata service

Creating a frontend

Now let’s add a simple web page to interact with our S3SyncClientResource. Quarkus automatically serves static resources located under the META-INF/resources directory. In the src/main/resources/META-INF/resources directory, add a s3.html file with the content from this s3.html file in it.

You can now interact with your REST service:

  • start Quarkus with ./mvnw compile quarkus:dev

  • open a browser to http://localhost:8080/s3.html

  • upload new file to the current S3 bucket via the form and see the list of files in the bucket

Next steps

Packaging

Packaging your application is as simple as ./mvnw clean package. It can be run with java -jar target/quarkus-app/quarkus-run.jar.

With GraalVM installed, you can also create a native executable binary: ./mvnw clean package -Dnative. Depending on your system, that will take some time.

Going asynchronous

Thanks to the AWS SDK v2.x used by the Quarkus extension, you can use the asynchronous programming model out of the box.

Create a org.acme.s3.S3AsyncClientResource that will be similar to our S3SyncClientResource but using an asynchronous programming model.

        }

        if (formData.mimetype == null || formData.mimetype.isEmpty()) {

        }

        return Uni.createFrom()
                .completionStage(() -> {
                    return s3.putObject(buildPutRequest(formData), AsyncRequestBody.fromFile(formData.data));
                })

                });
    }

    @Produces(MediaType.APPLICATION_OCTET_STREAM)
    public RestMulti<Buffer> downloadFile(String objectKey) {

                .completionStage(() -> s3.getObject(buildGetRequest(objectKey),
                        AsyncResponseTransformer.toPublisher())),
                response -> Multi.createFrom().safePublisher(AdaptersToFlow.publisher((Publisher<ByteBuffer>) response))
                        .map(S3AsyncClientResource::toBuffer),
                response -> Map.of("Content-Disposition", List.of("attachment;filename=" + objectKey), "Content-Type",
                        List.of(response.response().contentType())));
    }

    @GET
    public Uni<List<FileObject>> listFiles() {
        ListObjectsRequest listRequest = ListObjectsRequest.builder()
                .bucket(bucketName)
                .build();

        return Uni.createFrom().completionStage(() -> s3.listObjects(listRequest))
                .onItem().transform(result -> toFileItems(result));
    }

    private static Buffer toBuffer(ByteBuffer bytebuffer) {
        byte[] result = new byte[bytebuffer.remaining()];
        bytebuffer.get(result);
        return Buffer.buffer(result);
    }

    private List<FileObject> toFileItems(ListObjectsResponse objects) {
        return objects.contents().stream()
                .map(FileObject::from)
                .sorted(Comparator.comparing(FileObject::getObjectKey))
                .collect(Collectors.toList());
    }
}

And we need to add the Netty HTTP client dependency to the pom.xml:

<dependency>
    <groupId>software.amazon.awssdk</groupId>
    <artifactId>netty-nio-client</artifactId>
</dependency>

If you want to use the AWS CRT-based HTTP client instead, configure it as follows:

quarkus.s3.async-client.type=aws-crt

And add the following dependency to the application pom.xml:

<dependency>
    <groupId>software.amazon.awssdk</groupId>
    <artifactId>aws-crt-client</artifactId>
</dependency>

If you want to use the AWS CRT-based S3 client, add the io.quarkiverse.amazon.s3.runtime.S3Crt qualifier as follows:

@Inject
@S3Crt
S3AsyncClient s3;

And add the following dependency to the application pom.xml:

<dependency>
    <groupId>software.amazon.awssdk</groupId>
    <artifactId>aws-crt-client</artifactId>
</dependency>

S3 Transfer Manager

Amazon S3 Transfer Manager is high-level file transfer utility based on the S3 client. The extension provides functionality that allows to use S3TransferManager when running in Quarkus. You can find more information about S3 Transfer Manager at the Amazon S3 website.

S3 Transfer Manager and the Quarkus extension supports only Asynchronous programming based on JDK’s CompletableFuture objects and the Netty HTTP client (by default) or the AWS CRT-based HTTP client, or AWS CRT-based S3 client.

S3 Transfer Manager share the same configuration as S3 asynchronous client. See above to configure an S3AsyncClient.

If you want to use S3 Transfer Manager, configure an S3AsyncClient with the desired HTTP client library and simply inject an instance of S3TransferManager:

// Netty or AWS CRT-based HTTP client
@Inject
S3TransferManager transferManager;

// or AWS CRT-based S3 client
@Inject
@S3Crt
S3TransferManager transferManager;

And add the following dependency to the application pom.xml:

<dependency>
    <groupId>io.quarkiverse.amazonservices</groupId>
    <artifactId>quarkus-amazon-s3-transfer-manager</artifactId>
</dependency>

For all services but Cognito, the local AWS stack will be provided by LocalStack. Otherwise, it will be provided by Moto

Environment variable: QUARKUS_S3_DEVSERVICES_ENABLED

boolean

quarkus.s3.devservices.shared

Indicates if the LocalStack container managed by Dev Services is shared. When shared, Quarkus looks for running containers using label-based service discovery. If a matching container is found, it is used, and so a second one is not started. Otherwise, Dev Services starts a new container.

The discovery uses the quarkus-dev-service-localstack label. The value is configured using the service-name property.

Sharing is not supported for the Cognito extension.

Environment variable: QUARKUS_S3_DEVSERVICES_SHARED

boolean

false

quarkus.s3.devservices.isolated

Indicates if shared LocalStack services managed by Dev Services should be isolated. When true, the service will be started in its own container and the value of the quarkus-dev-service-localstack label will be suffixed by the service name (s3, sqs, …​)

Environment variable: QUARKUS_S3_DEVSERVICES_ISOLATED

boolean

true

quarkus.s3.devservices.service-name

The value of the quarkus-dev-service-localstack label attached to the started container. In dev mode, when shared is set to true, before starting a container, Dev Services looks for a container with the quarkus-dev-service-localstack label set to the configured value. If found, it will use this container instead of starting a new one. Otherwise it starts a new container with the quarkus-dev-service-localstack label set to the specified value. In test mode, Dev Services will group services with the same service-name value in one container instance.

This property is used when you need multiple shared LocalStack instances.

AWS services configurations

Type

Default

quarkus.s3.aws.region

quarkus.s3."client-name".aws.region

An Amazon Web Services region that hosts the given service.

It overrides region provider chain with static value of region with which the service client should communicate.

If not set, region is retrieved via the default providers chain in the following order:

  • aws.region system property

  • region property from the profile file

  • Instance profile file

See software.amazon.awssdk.regions.Region for available regions.

Environment variable: QUARKUS_S3_AWS_REGION

Region

quarkus.s3.aws.credentials.type

quarkus.s3."client-name".aws.credentials.type

Configure the credentials provider that should be used to authenticate with AWS.

Available values:

  • default - the provider will attempt to identify the credentials automatically using the following checks:

    • Java System Properties - aws.accessKeyId and aws.secretAccessKey

    • 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

    • Credentials delivered through the Amazon EC2 container service if AWS_CONTAINER_CREDENTIALS_RELATIVE_URI environment variable is set and security manager has permission to access the variable.

    • Instance profile credentials delivered through the Amazon EC2 metadata service

  • static - the provider that uses the access key and secret access key specified in the static-provider section of the config.

  • system-property - it loads credentials from the aws.accessKeyId, aws.secretAccessKey and aws.sessionToken system properties.

  • env-variable - it loads credentials from the AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY and AWS_SESSION_TOKEN environment variables.

  • profile - credentials are based on AWS configuration profiles. This loads credentials from a profile file, allowing you to share multiple sets of AWS security credentials between different tools like the AWS SDK for Java and the AWS CLI.

  • container - It loads credentials from a local metadata service. Containers currently supported by the AWS SDK are Amazon Elastic Container Service (ECS) and AWS Greengrass

  • instance-profile - It loads credentials from the Amazon EC2 Instance Metadata Service.

  • process - Credentials are loaded from an external process. This is used to support the credential_process setting in the profile credentials file. See Sourcing Credentials From External Processes for more information.

  • anonymous - It always returns anonymous AWS credentials. Anonymous AWS credentials result in un-authenticated requests and will fail unless the resource or API’s policy has been configured to specifically allow anonymous access.

About the Duration format

To write duration values, use the standard java.time.Duration format. See the Duration#parse() Java API documentation for more information.

You can also use a simplified format, starting with a number:

  • If the value is only a number, it represents time in seconds.

  • If the value is a number followed by ms, it represents time in milliseconds.

In other cases, the simplified format is translated to the java.time.Duration format for parsing:

  • If the value is a number followed by h, m, or s, it is prefixed with PT.

  • If the value is a number followed by d, it is prefixed with P.
About the MemorySize format

A size configuration option recognizes strings in this format (shown as a regular expression): [0-9]+[KkMmGgTtPpEeZzYy]?.

If no suffix is given, assume bytes.
