Deploy a Streamlit Service

In this guide, we will deploy a streamlit app using servicefoundry.

Before we begin,

  1. You need to have the servicefoundry
    library installed and login using the servicefoundry login command. If you do not have the library installed follow the instructions here.

  2. Go to the workspace page and create a workspace. Keep the workspace FQN handy. If you already have a workspace you can use that.

NOTE: A workspace is a resource (CPU, Memory) bound environment where we deploy jobs, services.

Writing our streamlit app

File Structure:

└── requirements.txt

import streamlit as st
import pandas as pd
import numpy as np

st.title("Uber pickups in NYC")

DATE_COLUMN = "date/time"

def load_data(nrows):
    data = pd.read_csv(DATA_URL, nrows=nrows)
    lowercase = lambda x: str(x).lower()
    data.rename(lowercase, axis="columns", inplace=True)
    data[DATE_COLUMN] = pd.to_datetime(data[DATE_COLUMN])
    return data

data_load_state = st.text("Loading data...")
data = load_data(10000)
data_load_state.text("Done! (using st.cache)")

if st.checkbox("Show raw data"):
    st.subheader("Raw data")

st.subheader("Number of pickups by hour")
hist_values = np.histogram(data[DATE_COLUMN].dt.hour, bins=24, range=(0, 24))[0]

# Some number in the range 0-23
hour_to_filter = st.slider("hour", 0, 23, 17)
filtered_data = data[data[DATE_COLUMN].dt.hour == hour_to_filter]

st.subheader("Map of all pickups at %s:00" % hour_to_filter)



NOTE: In the above code, we are downloading the data and caching it when the app loads for the first time. You can choose to keep the data file uber-raw-data-sep14.csv.gz in the same directory and read from there.

Deploying the streamlit app

We will deploy the streamlit app we wrote in the above section. You can either deploy using the python APIs or you can deploy using a YAML file and the servicefoundry deploy command.

Via Python

You can using Python API using:



You can deploy the training job with YAML file using the command below:

servicefoundry deploy --workspace-fqn YOUR_WORKSPACE_FQN --wait
