How to add a Rancher Pod based on one existent dockerfile?

1

Hi,
I have a custom container, based on a Dockerfile, that I create using the Docker command:
docker build -t my-container-img -f Dockerfile .

I’d like to add to Rancher a pod based on this dockerfile.
Is there a tutorial that explain how to create a Pod based on an existent Dockerfile?
Which are the steps i need to follow to do this?

thank you very much
