Streamlit on Pivotal (Cloud Foundry)

[hariharaprabhu]

Hi I am new here. I really love streamlit so far. I’m trying to deploy the streamlit app on PCF (Pivotal Cloud Foundry) and I am not successful yet. A custom url is created for my streamlit app in PCF, I’m not sure how to connect to this url instead of local host.

I tried the following ways:

1. streamlit run streamlit_aep.py --server.address (url)
2. Using a setup.sh similar to heroku

Any leads?

Thanks,
Hari

Hi @hariharaprabhu, welcome to the Streamlit community!

Pretty sure this is the first time Pivotal has ever come up, so unfortunately I don’t know the answer. Maybe someone else does, or if you figure it out, you can let us know so the next person has the answer

Thanks Randy. I’m trying to find the answer, if I get somewhere I will update over here. Appreciate your response.

Hi,

Finally got to deploy the app in Pivotal Cloud Foundry. For anyone, who is receiving a port error, please add this command to manifest file.

command: streamlit run app_name.py --server.port 8080 --server.enableCORS false

Your app code is not going to change for deployment. The rest of files need to be included is similar to a flask deployment in Pivotal.

I find this link useful:

First of all, thanks for sharing.
I am working on a similar project and get the fowlloing error:

Is there a way to run the server with CORS enabled?
Meaning, how can I specify allowed host?
Is there a --server.allowed hosts or something?
