# Railway Deployment Guide
2+
3+
## Automatic Deployment Setup
4+
5+
StackMemory includes automated deployment to Railway via GitHub Actions.
6+
7+
### Quick Setup
8+
9+
1. **Run the setup script:**
10+
```bash
11+
npm run railway:setup
12+
```
13+
This will:
14+
- Install Railway CLI
15+
- Link your Railway project
16+
- Generate required tokens
17+
- Guide you through GitHub secrets setup
18+
19+
2. **Add GitHub Secrets:**
20+
Go to your repository Settings → Secrets → Actions and add:
21+
- `RAILWAY_TOKEN` - Your Railway API token
22+
- `RAILWAY_PROJECT_ID` - Your Railway project ID
23+
24+
3. **Deploy:**
25+
Deployments happen automatically when you:
26+
- Push to `main` or `master` branch → Production deployment
27+
- Open a pull request → Preview deployment
28+
29+
### Manual Deployment
30+
31+
```bash
32+
# Deploy current branch
33+
npm run railway:deploy
34+
35+
# View logs
36+
npm run railway:logs
37+
```
38+
39+
## GitHub Actions Workflows
40+
41+
### Production Deployment (.github/workflows/railway-deploy.yml)
42+
- Triggers on push to main/master
43+
- Runs tests before deploying
44+
- Posts deployment status as commit comment
45+
- Deploys to production environment
46+
47+
### Preview Deployments (.github/workflows/railway-preview.yml)
48+
- Triggers on pull requests
49+
- Creates isolated preview environment
50+
- Posts preview URL as PR comment
51+
- Auto-cleans up when PR is closed
52+
53+
## Railway Configuration
54+
55+
### railway.json
56+
Configures build and deploy settings:
57+
- Build command: `npm run build`
58+
- Start command: `npm start`
59+
- Health check endpoint: `/health`
60+
- Auto-restart on failure (max 3 retries)
61+
62+
### Environment Variables
63+
Set these in Railway dashboard:
64+
65+
#### Required
66+
- `REDIS_URL` - Redis connection (use Railway Redis addon)
67+
- `LINEAR_API_KEY` - Linear API key for task sync
68+
- `CHROMADB_API_KEY` - ChromaDB for vector storage
69+
70+
#### Optional
71+
- `DATABASE_URL` - PostgreSQL connection (use Railway PostgreSQL addon)
72+
- `GCS_BUCKET_NAME` - Google Cloud Storage for cold tier
73+
- `SENTRY_DSN` - Error tracking
74+
- `PORT` - Server port (Railway sets automatically)
75+
76+
### Railway Addons
77+
78+
1. **Redis** (Required for hot tier storage)
79+
- Add via Railway dashboard
80+
- Auto-populates `REDIS_URL`
81+
82+
2. **PostgreSQL** (Optional)
83+
- For persistent metadata
84+
- Auto-populates `DATABASE_URL`
85+
86+
## Storage Tiers on Railway
87+
88+
StackMemory uses a 3-tier storage system optimized for Railway:
89+
90+
1. **Hot Tier (Redis)**
91+
- Recent traces (<24 hours)
92+
- High-score traces
93+
- Railway Redis addon
94+
- LRU eviction, 100MB limit
95+
96+
2. **Warm Tier (Railway Volumes)**
97+
- Mid-age traces (1-30 days)
98+
- Railway persistent volumes
99+
- Compressed storage
100+
101+
3. **Cold Tier (GCS)**
102+
- Old traces (>30 days)
103+
- Google Cloud Storage Coldline
104+
- $0.004/GB/month
105+
106+
## Monitoring
107+
108+
### Health Check
109+
Railway monitors `/health` endpoint:
110+
```javascript
111+
// Automatically included in deployment
112+
app.get('/health', (req, res) => {
113+
res.json({
114+
status: 'healthy',
115+
redis: redisClient.isReady,
116+
storage: storageSystem.status
117+
});
118+
});
119+
```
120+
121+
### Logs
122+
```bash
123+
# View live logs
124+
npm run railway:logs
125+
126+
# Via Railway CLI
127+
railway logs --tail
128+
129+
# Filter by service
130+
railway logs --service stackmemory
131+
```
132+
133+
## Troubleshooting
134+
135+
### Deployment Fails
136+
1. Check GitHub Actions logs
137+
2. Verify secrets are set correctly
138+
3. Ensure tests pass locally: `npm test`
139+
4. Check Railway dashboard for errors
140+
141+
### Redis Connection Issues
142+
1. Verify Redis addon is provisioned
143+
2. Check `REDIS_URL` in environment variables
144+
3. Test locally with Railway proxy:
145+
```bash
146+
railway run npm start
147+
```
148+
149+
### Preview Deployments Not Working
150+
1. Ensure `RAILWAY_TOKEN` has project access
151+
2. Check PR has no merge conflicts
152+
3. Verify GitHub Actions are enabled
153+
154+
## Cost Optimization
155+
156+
### Railway Free Tier
157+
- 500 hours/month execution time
158+
- 100GB bandwidth
159+
- Suitable for development
160+
161+
### Production Recommendations
162+
- Use Railway Pro for production
163+
- Enable auto-scaling for traffic spikes
164+
- Monitor resource usage in dashboard
165+
- Use Redis maxmemory policies
166+
167+
## Security
168+
169+
### Secrets Management
170+
- Never commit `.env` files
171+
- Use Railway's environment variables
172+
- Rotate tokens regularly
173+
- Use read-only tokens where possible
174+
175+
### Network Security
176+
- Railway provides HTTPS by default
177+
- Private networking between services
178+
- IP allowlisting available on Pro plan
179+
180+
