AWS App Runner

Introduction

AWS App Runner is a fully managed service that makes it easy for developers to quickly deploy containerized web applications and APIs at scale.

It abstracts infrastructure management, allowing developers to focus on writing code without worrying about the underlying resources.

Key Concepts

**Managed Service**: No need to manage servers or clusters.
**Containers**: Deploys applications packaged in containers.
**Automatic Scaling**: Automatically scales your applications based on traffic.
**Custom Domains**: Supports custom domains for your applications.
**Integrated Monitoring**: Provides built-in monitoring and logging with Amazon CloudWatch.

Note: App Runner supports applications built with any programming language or framework that can run in a container.

Step-by-Step Process

Deploying an Application on App Runner

**Prepare Your Code**: Ensure your application is containerized.
**Push to Source Control**: Push your code to a repository (e.g., GitHub).

**Create App Runner Service**:

aws apprunner create-service --service-name YourServiceName \
                        --source-configuration '{"ImageRepository": {"ImageIdentifier": "your-image", "ImageRepositoryType": "ECR", "ImageConfiguration": {"Port": "8080"}}}'

**Test Your Application**: Access the default App Runner URL to test your application.
**Set Up Custom Domain (Optional)**: Map your custom domain to the App Runner service.

Best Practices

Use environment variables for sensitive information.
Implement health checks to monitor application status.
Optimize container images to reduce deployment times.
Utilize AWS IAM roles for secure access to resources.
Regularly review and adjust scaling settings based on usage patterns.
