How to run streamlit apps in pants?

[rhuanbarreto]

Streamlit can only run through its CLI by doing streamlit run /path/to/source.py, so I wonder how can I run streamlit in pants once the run needs a pex binary as an input?

Using Pants <2.16.0.dev5

# some/BUILD
pex_binary(name="bin", script="streamlit", dependencies=[<streamlit app>])

$ pants run some:bin -- run <streamlit app>

Using Pants >=2.16.0.dev5

# some/BUILD
pex_binary(name="bin", script="streamlit", args=["run", <streamlit app>], dependencies=[<streamlit app>])

$ pants run some:bin

It runs but still doesn't work as expected. It redirects me to localhost:3000 but the port should be 8501. And going to port 8501 gives me a 404.

It worked when doing pants run some:bin -- run <streamlit app> --server.port 8501 --global.developmentMode false. But still not clear how to send the config file so I don't need to set into the CLI.

Something like this might be in the right direction:

resources(name="config", sources=["*.cfg"])
pex_binary(.., dependencies=[":config"])
