it uses the port 5000, can lambda open any port?
Yup! Change the `handler` and `start` command:
``` handler = "localhost:5000" ... start = "poetry run flask --app flask_poetry run -p 12345" ```
``` handler = "localhost:5000" ... start = "poetry run flask --app flask_poetry run -p 12345" ```
is this port publicly accessible? or the traffic is forwarded by lambda's interface?
It's not publicly accessible, per-se..., there's a reverse proxy I've written
1. There's a Function URL that then creates a Lambda HTTP Event
2. There's a reverse proxy in the container that converts the Lambda HTTP Event back into a HTTP Request
3. Then the HTTP Respose is transformed back into a Lambda HTTP Event Response
@billconan if you'd like, join my Discord and I'd be happy dive into details and/or provide more docs: https://scaffoldly.dev/community

In this example, we're running a Flask server in AWS Lambda, and the scaffoldly toolchain handles packaging, deployment, and routing of AWS Lambda HTTP requests.
