Unable to use different port on docker?

I use this command: docker run -d --name=api-umbrella -p 8000:80 -p 8443:443 -v "$(pwd)/config":/etc/api-umbrella nrel/api-umbrella

Browse to http://localhost:8000 always redirect to https://localhost

Is there any configuration to:

1. use different port
2. force using http

Please enlighten me. Thanks in advance.
