GPT Text Summarizer Deployment Steps

This guide will walk you through building and deploying your Streamlit-based GPT text summarizer app using Docker and Azure services.

---

1. Prepare Docker Image

1. Create requirements.txt

   pip freeze > requirements.txt

2. Create a Dockerfile

3. Build the Docker image

   docker build -t testimage .

4. Verify the image

   docker images

5. Run Docker

   docker run -p 8501:8501 testimage

6. Access the app
   Navigate to → http://localhost:8501

2. ☁️ Create an Azure Container Registry (ACR) and Push the Image

From Azure Portal:

• Create new ACR (Private Network recommended)
• If access error when pushing:
  • Go to ACR > Networking and allow specific IP ranges
  • Go to ACR > Access Keys → enable Admin user

From Azure CLI:

az login
az acr list --resource-group <resource-group-name> --output table
az account set --subscription "<subscription-id>"
az acr login --name <acr-name>

# Tag and Push Docker Image

docker tag <your_image_name> <acr-name>.azurecr.io/<your_image_name>:latest
docker push <acr-name>.azurecr.io/<your_image_name>:latest

# If error, re-authenticate or adjust IP access range

az acr repository list --name <acr-name> --output table
az acr credential show --name <acr-name>

Deploy from Azure Portal:

• Go to ACR > Repositories → select image → Tags → Deploy to WebApp
• Fill in:
  • Web App name
  • Service Plan

3. App Registration & Authentication Setup

1. Go to Azure → App Registrations
2. Locate your app → Note down Application (client) ID
3. Add Platform → Web →
   • Add Redirect URI:

     https://<your-app-name>.azurewebsites.net/.auth/login/aad/callback
     

4. Enable:
   • ✅ ID tokens
   • ✅ Accounts in this organizational directory only

---

4. 👥 Restrict User Access

• Azure Portal → Enterprise Applications → Find your app
• Assign access:
  • Users and Groups → Add user or group → Use Application (client) ID

---

5. ⚙️ Adjust WebApp Settings

• Authentication
  • Enable App Service authentication
  • Require login for access
  • Identity Provider → Microsoft → use your Application (client) ID

---

6. 🔍 Monitor & Secrets

• Monitor Logs from Azure → WebApp Logs

• Add secrets to Key Vault:

  Key: gptappkey
  Value: <your-secret>
  

• Docs: Azure Manage Secrets
