AWS App Runner now supports deploying services from source code repositories that follow a monorepo structure. App Runner makes it easier for developers to quickly deploy containerized web applications and APIs to the cloud, at scale, and without managing infrastructure. With App Runner build-from-source capability you can offload the build and deployment workflow management to App Runner and deploy services directly from source code. App Runner provides convenient platform-specific managed runtimes. Each one of these runtimes builds a container image from your source code, and adds language runtime dependencies into your application container image.
