# Deployment Guide
2+
3+
This document provides step-by-step instructions for deploying the Sentiment Analysis app to public platforms.
4+
5+
## Troubleshooting Streamlit Cloud
6+
7+
**Status**: Currently unavailable (403 Forbidden error)
8+
9+
### Issue Description
10+
When attempting to access Streamlit Cloud deployments, the platform returns:
11+
```
12+
Error: Forbidden
13+
Your client does not have permission to get URL / from this server
14+
```
15+
16+
### Root Cause
17+
This is a platform-side access restriction (likely account/region-based), not a code issue. The local app and code are fully functional.
18+
19+
### Workarounds
20+
Deploy to alternative platforms (see below) instead.
21+
22+
---
23+
24+
## ✅ Recommended Deployment Options
25+
26+
### 1. Hugging Face Spaces (Easiest)
27+
28+
**Pros**: Free, auto-deploy on GitHub push, no account restrictions observed
29+
30+
**Steps**:
31+
1. Create account at https://huggingface.co
32+
2. Navigate to https://huggingface.co/spaces
33+
3. Click "Create new Space"
34+
4. Select "Streamlit" as the space SDK
35+
5. Upload or connect your GitHub repository
36+
6. Spaces auto-deploys the app
37+
38+
**Your public URL**: https://huggingface.co/spaces/[username]/[space-name]
39+
40+
**Config**: Spaces automatically detects `app.py` and `requirements.txt`
41+
42+
---
43+
44+
### 2. Railway.app (Easy, Free Tier)
45+
46+
**Pros**: Simple GitHub integration, good uptime, free tier available
47+
48+
**Steps**:
49+
1. Sign up at https://railway.app
50+
2. Connect your GitHub account
51+
3. Create new project from GitHub repo
52+
4. Railway auto-detects and suggests deployment
53+
5. Add environment variable: `PORT=8501`
54+
6. Deploy
55+
56+
**Your public URL**: `https://[project-name].railway.app` (auto-generated)
57+
58+
---
59+
60+
### 3. Render.com (Very Easy)
61+
62+
**Pros**: GitHub integration, free tier, easy setup
63+
64+
**Steps**:
65+
1. Sign up at https://render.com
66+
2. Connect GitHub account
67+
3. Create "New Web Service" from repository
68+
4. Set build command: `pip install -r requirements.txt`
69+
5. Set start command: `streamlit run app.py --server.port=10000`
70+
6. Add environment variable: `PORT=10000`
71+
7. Deploy
72+
73+
**Your public URL**: Auto-generated by Render
74+
75+
---
76+
77+
### 4. Local SSH Tunnel (Temporary Sharing)
78+
79+
**Pros**: No account needed, instant public URL
80+
81+
**Cons**: Temporary (URL changes each restart), requires keeping local app running
82+
83+
**Steps**:
84+
```bash
85+
# Terminal 1: Start the app locally
86+
streamlit run app.py
87+
88+
# Terminal 2: Create tunnel
89+
ssh -o StrictHostKeyChecking=no -R 80:localhost:8501 nokey@localhost.run
90+
```
91+
92+
This generates a public HTTPS URL like: `https://abc123def456.lhr.life`
93+
94+
**Note**: The URL changes each time you restart the tunnel.
95+
96+

97+

## Deployment Checklist
99+
100+
- [ ] Test locally: `streamlit run app.py`
101+
- [ ] Verify `requirements.txt` has all dependencies
102+
- [ ] Verify `app.py` works as entry point
103+
- [ ] Push code to GitHub
104+
- [ ] Choose deployment platform (HF Spaces recommended)
105+
- [ ] Follow platform-specific steps above
106+
- [ ] Test deployed app
107+
- [ ] Share public URL
108+
109+

## Monitoring & Maintenance
112+
113+
### After Deployment
114+
115+
1. **Test the app**: Click links, type test inputs
116+
2. **Monitor performance**: Check platform dashboard
117+
3. **Update code**: Push changes to GitHub → platform auto-redeploys
118+
4. **Check logs**: Platforms provide error logs if issues occur
119+
120+
### Common Issues After Deployment
121+
122+
| Issue | Solution |
123+
|-------|----------|
124+
| Slow first load | Model downloads on first request (~2-3 min) - normal for first use |
125+
| "Module not found" | Ensure all packages are in `requirements.txt` |
126+
| Out of memory | Platform may have limited resources; consider model optimization |
127+
| Timeout errors | App might be taking too long; check logs on platform dashboard |
128+
129+
---
130+
131+
## Docker Deployment (Advanced)
132+
133+
For platforms requiring Docker:
134+
135+
```dockerfile
136+
FROM python:3.10-slim
137+
138+
WORKDIR /app
139+
140+
COPY requirements.txt .
141+
RUN pip install -r requirements.txt
142+
143+
COPY . .
144+
145+
EXPOSE 8501
146+
147+
CMD ["streamlit", "run", "app.py", "--server.port=8501", "--server.address=0.0.0.0"]
148+
```
149+
150+
---
151+
152+
## Automating Deployments
153+
154+
### GitHub Actions Example
155+
156+
Create `.github/workflows/deploy.yml`:
157+
158+
```yaml
159+
name: Deploy to Hugging Face
160+
161+
on:
162+
push:
163+
branches: [main]
164+
165+
jobs:
166+
deploy:
167+
runs-on: ubuntu-latest
168+
steps:
169+
- uses: actions/checkout@v2
170+
- name: Push to Hugging Face
171+
env:
172+
HF_API_KEY: ${{ secrets.HF_API_KEY }}
173+
run: |
174+
git config user.name "GitHub Action"
175+
git config user.email "action@github.com"
176+
git remote set-url origin https://x-access-token:${HF_API_KEY}@huggingface.co/spaces/username/space-name
177+
git push -u origin main
178+
```
179+
180+
