# Docker Deployment Infrastructure - Setup Summary
Complete Docker deployment infrastructure has been created for the Komodo MCP server. This document provides an overview of all created files and their purposes.
## Files Created
### 1. Dockerfile (Production)
**Location:** `C:\Users\Matt.Ravenscroft\Documents\Claude Stuff\komodo-mcp\Dockerfile`
Multi-stage build Dockerfile for production deployments:
**Features:**
- **Stage 1 (Builder):** Compiles TypeScript to JavaScript
- **Stage 2 (Runtime):** Lightweight Node.js 20 Alpine base image
- Non-root user for security (nodejs:nodejs)
- dumb-init for proper signal handling
- Health check configured
- Ports 1111-1120 exposed
- Size optimized (~200MB)
**Key configurations:**
```dockerfile
FROM node:20-alpine AS builder # Builder stage
FROM node:20-alpine # Final stage
RUN adduser -S nodejs -u 1001 # Non-root user
EXPOSE 1111 # Primary port
HEALTHCHECK --interval=30s ... # Auto health checks
ENTRYPOINT ["/usr/sbin/dumb-init", "--"]
CMD ["node", "dist/index.js"]
```
### 2. Dockerfile.dev (Development)
**Location:** `C:\Users\Matt.Ravenscroft\Documents\Claude Stuff\komodo-mcp\Dockerfile.dev`
Development Docker image with debugging and hot reload:
**Features:**
- Development dependencies included
- Debug port 9229 exposed
- Node.js inspector enabled
- Hot reload capability
- Verbose logging
**Key configurations:**
```dockerfile
ENV NODE_ENV=development
EXPOSE 1111 # MCP server port
EXPOSE 9229 # Debug port
CMD ["node", "--inspect=0.0.0.0:9229", "dist/index.js"]
```
### 3. docker-compose.yml
**Location:** `C:\Users\Matt.Ravenscroft\Documents\Claude Stuff\komodo-mcp\docker-compose.yml`

### 5. .dockerignore
**Location:** `C:\Users\Matt.Ravenscroft\Documents\Claude Stuff\komodo-mcp\.dockerignore`
Specifies files and directories excluded from Docker build context:
**Excludes:**
- node_modules, npm-debug.log, yarn-error.log
- dist, build, *.tsbuildinfo
- tests, *.spec.ts, *.test.ts, coverage
- docs, *.md, README, CHANGELOG

## Deployment Profiles
### 1. Default Profile
Single instance deployment:
```bash
./scripts/docker-deploy.sh start default
# Starts: komodo-mcp-1 on port 1111
```
### 2. Scaled Profile
Three instances for high availability:
```bash
./scripts/docker-deploy.sh start scaled
# Starts:
# - komodo-mcp-1 on port 1111
# - komodo-mcp-2 on port 1112
# - komodo-mcp-3 on port 1113
```
### 3. Load-Balanced Profile
Scaled deployment with Nginx load balancer:
```bash
./scripts/docker-deploy.sh start load-balanced
# Starts:
# - nginx-lb (load balancer) on port 1110
# - komodo-mcp-1 on port 1111
# - komodo-mcp-2 on port 1112
# - komodo-mcp-3 on port 1113
```
### 4. Development Profile
Development environment with hot reload:
```bash
./scripts/docker-deploy.sh start dev
# Starts komodo-mcp-1 with:
# - Hot reload enabled
# - Debug port 9229
# - Development dependencies
```

# Using deployment script
./scripts/docker-deploy.sh build
# Or using Docker Compose
docker-compose build
```
### 3. Start Containers
```bash
# Start default profile
./scripts/docker-deploy.sh start
# Or scaled profile
./scripts/docker-deploy.sh start scaled
# Or with load balancer
./scripts/docker-deploy.sh start load-balanced
```
### 4. Verify Deployment
```bash
# Check container status
docker-compose ps
# Run health checks
./scripts/docker-deploy.sh health
# View logs
./scripts/docker-deploy.sh logs
```
### 5. Access Services
```bash
# Direct instance access
curl http://localhost:1111

# Load balancer health
curl http://localhost:1110/health
# Load balancer metrics
curl http://localhost:1110/metrics
```
## Security Features
1. **Non-Root User:**
- Runs as nodejs:nodejs (uid: 1001, gid: 1001)
- Prevents privilege escalation
2. **Multi-Stage Build:**
- Final image doesn't include build tools
- Reduces attack surface
3. **Alpine Base:**
- Minimal image (~50MB base)
- Fewer vulnerabilities
4. **Signal Handling:**
- dumb-init handles signals properly
- Graceful shutdown
5. **Health Checks:**
- Automatic restart on failure
- Failure detection and recovery
## Performance Considerations
1. **Resource Limits:**
- Configure in docker-compose.yml
- Prevents resource starvation
2. **Log Rotation:**
- json-file driver with rotation
- Prevents disk space issues
3. **Connection Pooling:**
- Nginx keepalive 32
- Reuses connections
4. **Load Balancing:**
- least_conn algorithm
- Distributes traffic fairly
5. **Caching:**
- Docker layer caching during builds
- Efficient image rebuilds
## Monitoring and Logging
1. **Container Logs:**
- Available via `docker-compose logs`
- Stored in `./logs/` directory
- Rotated to prevent disk issues
2. **Health Status:**
- Checked every 30 seconds
- Containers auto-restart on failure
3. **Deployment Script:**
- `./scripts/docker-deploy.sh health` - Check all instances
- `./scripts/docker-deploy.sh logs` - View logs
- `./scripts/docker-deploy.sh logs-all` - View all logs
## Next Steps
1. **Configure Environment:**
- Edit `.env` with Komodo API credentials
- Verify all required variables
2. **Build Image:**
- Run `./scripts/docker-deploy.sh build`
- Verify build completes successfully
3. **Start Deployment:**
- Choose deployment profile
- Run appropriate start command
- Verify health checks pass
4. **Monitor:**
- Watch logs for issues
- Set up monitoring/alerting
- Plan scaling strategy
5. **Production Checklist:**
- Review `docs/DOCKER.md` Production Checklist section
- Verify all security measures
- Test failover procedures
- Set up monitoring dashboard
## Troubleshooting
For common issues and detailed troubleshooting, see `docs/DOCKER.md` troubleshooting section.
**Common issues:**
- Container won't start
- Connection refused
- Health check failing
- Out of disk space
- High memory usage
- Network issues
Each includes diagnosis and resolution steps.
