Deploy Quarkus application to AWS Elastic Beanstalk

Elastic Beanstalk allows deploying and managing applications in the AWS Cloud without having to learn about the infrastructure that runs those applications.With Elastic Beanstalk you can run a website, web application, or web API that serves HTTP requests but you can also run a worker applications for running long tasks. The Elastic Beanstalk supports several preconfigured platforms including Go, .NET or Java (Java 8 only) but also generic Docker platform.You simply upload your application with AWS CLI, AWS EB CLI or with the Elastic Beanstack console, and Elastic Beanstalk automatically handles the rest.In this blog post you will learn how to launch single container Docker environment with Quarkus based application on Elastic Beanstalk.

Quarkus tests with Testcontainers and PostgreSQL
