+# Sinatra example
+A basic example of a Sinatra application.
+
+Using AWS Lambda Adapter, You can package this web application into Docker image, push to ECR, and deploy to Lambda, ECS/EKS, or EC2.
+
+The application can be deployed in an AWS account using the [Serverless Application Model](https://github.com/awslabs/serverless-application-model). The `template.yaml` file in the root folder contains the application definition.
+
+The top level folder is a typical AWS SAM project. The `app` directory is a Sinatra application with a Dockerfile.
+
+```dockerfile
+FROM public.ecr.aws/docker/library/ruby:3.3
+COPY --from=public.ecr.aws/awsguru/aws-lambda-adapter:0.8.1 /lambda-adapter /opt/extensions/lambda-adapter
+WORKDIR /var/task
+COPY Gemfile Gemfile.lock ./
+RUN bundle install
+COPY . .
+CMD ["bundle", "exec", "ruby", "app.rb", "-o", "0.0.0.0", "-p", "8080"]
+```
+
+## Pre-requisites
+
+The following tools should be installed and configured.
+* [AWS CLI](https://aws.amazon.com/cli/)
+* [SAM CLI](https://github.com/awslabs/aws-sam-cli)
+* [Docker](https://www.docker.com/products/docker-desktop)
+* [Ruby](https://www.ruby-lang.org/)
+
+## Deploy to Lambda
+
+Navigate to the sample's folder and use the SAM CLI to build a container image:
+
+```shell
+$ sam build
+```
+
+This command compiles the application and prepares a deployment package in the `.aws-sam` sub-directory.
+
+To deploy the application in your AWS account, you can use the SAM CLI's guided deployment process and follow the instructions on the screen:
+
+```shell
+$ sam deploy --guided
+```
+
+Please take note of the container image name.
+Once the deployment is completed, the SAM CLI will print out the stack's outputs, including the new application URL. You can use `curl` or a web browser to make a call to the URL.
+
+NOTE: This SAM does not use Amazon API Gateway, but uses AWS Lambda function URLs to create HTTP endpoints.
+
+```shell
+...
+CloudFormation outputs from deployed stack
+-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
+Outputs
+-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
+Key SinatraFunction1
+Description Function URL endpoint on AWS Lambda
+Value https://xxxxxxxxxxxxxxxxxxxxxxxxx.lambda-url.REGION.on.aws/
+-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------...
+
+$ curl https://xxxxxxxxxxxxxxxxxxxxxxxxx.lambda-url.REGION.on.aws/
+```
+
+## Run the docker locally
+
+We can run the same docker image locally, so that we know it can be deployed to ECS Fargate and EKS EC2 without code changes.
+
+```shell
+$ docker run -it --rm -p 8080:8080 {ECR Image}
+```
+
+Use curl from another session to checking that the Docker container is working.
+
+```shell
+$ curl localhost:8080/
+#=> Hello! I am Sinatra.
+```
