Hello! Thank you for your contribution to bee-agent-framework. We value your time and effort.

• This does not address Add a container executable agent #134 in any way.
• The Dockerfile isn't valid --node:alpine:latest isn't a valid image specifier.
• The Dockerfile is actually called DockerFile with capital F, which is not valid.
• Proper .dockerignore is missing.
• This project uses yarn.
• "npm start" doesn't do anything by itself.

We kindly ask you to ensure that you actually run new code before contributing it.

#134 misses clarifying the final goal. How can one implement something that we do not know what it is?
Dockerization is not something that should be part of this library. However, it makes sense to do such a thing at https://github.com/i-am-bee/bee-agent-framework-starter
