This example demonstrates how to use the docker images provided in this repository.

To build the Docker image, navigate to the directory containing the Dockerfile and run the following command:

docker build --build-arg LAMBDA_TASK_ROOT=/var/task --build-arg LAMBDA_USER=lambda-user --build-arg LAMBDA_GROUP=lambda-group -t aws-lamdba-example .

To run the Docker container, use the following command:

docker run -p 9000:8080 aws-lamdba-example

This will start an interactive terminal session inside the container.

You can test the Lambda function by sending a POST request to the local endpoint. Use the following curl command:

Invoke-WebRequest -Uri "http://localhost:9000/2015-03-31/functions/function/invocations" -Method Post -ContentType "application/json" -Body '{}'

This command sends an empty JSON object as the event to the Lambda function. You should see a response from the function indicating that it was invoked successfully.

For example, the response might look like this:

StatusCode        : 200
StatusDescription : OK
                    Content-Length: 102
                    Content-Type: text/plain; charset=utf-8
                    Date: Thu, 04 Sep 2025 03:26:14 GMT

                    {"statusCode": 200, "body": "Hello from Lambda!. I see you are using priceless_mur...
Forms             : {}
Headers           : {[Content-Length, 102], [Content-Type, text/plain; charset=utf-8], [Date, Thu, 04 Sep 2025 03:26:14 GMT]}
Images            : {}
InputFields       : {}
Links             : {}
ParsedHtml        : mshtml.HTMLDocumentClass
RawContentLength  : 102

To stop the Docker container, you can use the following command:

docker stop <container_id>

Replace <container_id> with the actual ID of the running container, which you can find by running docker ps.

To remove the Docker image, use the following command:

docker rmi aws-lamdba-example

This will delete the image from your local Docker repository.
