How to assign a port when containerize bentoml

[OriAlpha]

When i containerize a model by default its assigned to port 3000, but if i want to run on different port its not possible.
For example:

docker run -it --rm -p 3000:3000 model:tag serve --production
when i curl to this via 3000 it works

But when i run same on different port as 6000
docker run -it --rm -p 6000:6000 model:tag serve --production
curl just fails, so can assign a port while containerize model

bentoml containerize model:latest some where here

containerize doesn't have the responsibility to set the container port.

What are you running on port 6000?

If you are running a separate ASGI app on such port, you probably need custom dockerfile and expose that PORT via the dockerfile. See https://docs.bentoml.org/en/latest/guides/containerization.html#dockerfile-template

docker run -p exposes the ports of that container, so obv if you don't have anything running on 6000 it won't work.

6000 port is free, but curl doesnt work

docker run -it --rm -p 6000:6000 model:gcyks3g47o4zyo3f serve --production

i could see the file structure, where the docker file is create when model is converted to bentoml local format.
https://docs.bentoml.org/en/latest/concepts/bento.html
I use

model = bentoml.bentos.build(service="svc.py:service",include=['svc.py'],
                                     python=dict(requirements_txt="requirements.txt",),
                                     docker=dict(python_version="3.8"))

is there a way to modify in bentoml.bentos.build python function
