Accessing AWS Systems Manager / Parameter Store's Configuration from Quarkus

The Parameter Store is part of the AWS Systems Manager (SSM) and provides a centralized store to manage your configuration data, whether plain-text data such as database strings or secrets such as passwords.

Quarkus ships with SSM Client which provides access to SSM:

The SSM was accessed in the JAX-RS resource:

import javax.inject.Inject;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;

import software.amazon.awssdk.services.ssm.SsmClient;
import software.amazon.awssdk.services.ssm.model.GetParameterRequest;

@Path("/hello")
public class GreetingResource {

@Inject
SsmClient client;

@GET
@Produces(MediaType.TEXT_PLAIN)
public String hello() {
    var req = GetParameterRequest.builder().name("greetings").build();
    return this.client.getParameter(req).parameter().value();
    }
}

application.properties:

quarkus.ssm.aws.region=eu-central-1
quarkus.ssm.aws.credentials.profile-provider.profile-name=default

The credentials were maintained in ~/.aws/credentials:

[default]
aws_access_key_id = ACCESKEYF435AERf4
aws_secret_access_key = secretpui8mnlkuasdfeaxae534
