Deploying Streamlit Apps Intermediate

Once your Streamlit app is ready, you need to deploy it so others can access it. This lesson covers Streamlit Community Cloud (free), Docker, Hugging Face Spaces, and cloud providers like AWS and GCP.

Streamlit Community Cloud

The easiest way to deploy — free hosting directly from your GitHub repository:

  1. Push your app to GitHub

    Your repository should contain app.py and requirements.txt.

  2. Go to share.streamlit.io

    Sign in with your GitHub account and click "New app."

  3. Select your repository

    Choose the repo, branch, and main file path (e.g., app.py).

  4. Click Deploy

    Your app will be live in minutes at https://your-app.streamlit.app.

requirements.txt 
streamlit==1.37.0
pandas==2.1.0
plotly==5.18.0
scikit-learn==1.3.0
Secrets on Community Cloud: Add secrets through the app settings dashboard (not in your repository). Access them with st.secrets["KEY"] or via a .streamlit/secrets.toml file locally.

Docker Deployment

Dockerfile 
FROM python:3.11-slim

WORKDIR /app

COPY requirements.txt .
RUN pip install --no-cache-dir -r requirements.txt

COPY . .

EXPOSE 8501

HEALTHCHECK CMD curl --fail http://localhost:8501/_stcore/health

ENTRYPOINT ["streamlit", "run", "app.py", "--server.port=8501", "--server.address=0.0.0.0"]
Terminal 
# Build and run
docker build -t my-streamlit-app .
docker run -p 8501:8501 my-streamlit-app

Hugging Face Spaces

Deploy on HF Spaces for free with the Streamlit SDK:

YAML (README.md)

Cloud Provider Deployment

Platform Method Cost
AWS ECS/Fargate with Docker, or EC2 Pay per use
GCP Cloud Run (Docker), App Engine, or GCE Pay per use (free tier available)
Azure Azure Container Apps or App Service Pay per use
Railway Direct from GitHub, auto-detect Free tier + pay per use
Render Docker or direct Python deployment Free tier available

Google Cloud Run Example

Terminal 
# Build and push to Google Container Registry
gcloud builds submit --tag gcr.io/MY_PROJECT/my-streamlit-app

# Deploy to Cloud Run
gcloud run deploy my-streamlit-app \
  --image gcr.io/MY_PROJECT/my-streamlit-app \
  --port 8501 \
  --allow-unauthenticated
