The Terraform AWS provider now supports AWS AppRunner, a purpose-built container application service that enables customers to build and run containerized web applications with no infrastructure overhead. With App Runner, users can provide their source code or image repository and have it automatically built, deployed, and scaled based on incoming request traffic. To set up App Runner in the Terraform AWS provider, users need to create a few new resources, including an `aws_apprunner_connection`, `aws_apprunner_service`, and `aws_apprunner_custom_domain_association`. Once configured, App Runner provides automatic deployments, high performance, scalability, and security. Additional information can be found in the AWS App Runner documentation and blog post.
