 Another docker image to deploy serverless in AWS Lambda is provided in [Dockerfile.lambda](Dockerfile.lambda). The image is based on the official AWS Lambda Python 3.11 image. For extending this image the process is the same as the main image.
 
-```console
-$ docker build -t eidos-lambda -f Dockerfile.lambda .
+```bash
+docker build -t eidos-lambda -f Dockerfile.lambda .
 ```
 
 Run the container locally with the following command or deploy in AWS Lambda as a docker container image:

 ```bash
-docker run --rm -p 9001:8080 eidos-lambda
+docker run --rm -p 8091:8080 eidos-lambda
