2. Install Docker

# Ubuntu/Debian
sudo apt update
sudo apt install -y docker.io docker-compose

# Add user to docker group
sudo usermod -aG docker $USER

# Start Docker service
sudo systemctl start docker
sudo systemctl enable docker

3. Install Protocol Buffers

sudo apt install -y protobuf-compiler

# Verify
protoc --version  # Should show libprotoc 3.21.12 or higher

4. Install Go Development Tools

# Ensure GOPATH is set
export GOPATH=$HOME/go
export PATH=$PATH:$GOPATH/bin

# Install tools
go install golang.org/x/tools/cmd/goimports@latest
go install google.golang.org/protobuf/cmd/protoc-gen-go@latest
go install google.golang.org/grpc/cmd/protoc-gen-go-grpc@latest

# Install golangci-lint
curl -sSfL https://raw.githubusercontent.com/golangci/golangci-lint/master/install.sh | \
  sh -s -- -b $(go env GOPATH)/bin v1.55.2

5. Clone and Build

# Build
make build

6. Set Up MongoDB (Production)

For production deployment with ZFS on NVMe for optimal performance:

# See INFRASTRUCTURE.md for complete setup guide

# Quick setup on remote VM:
# 1. Create ZFS pool on NVMe
ssh user@your-vm "sudo zpool create -f -o ashift=12 -O compression=lz4 \
  -O atime=off -O recordsize=16K mongopool /dev/nvme0n1"

# 2. Create MongoDB dataset
ssh user@your-vm "sudo zfs create -o mountpoint=/var/lib/mongodb \
  mongopool/mongodb"

# 3. Install MongoDB 7.0+
ssh user@your-vm "curl -fsSL https://www.mongodb.org/static/pgp/server-7.0.asc | \
  sudo gpg -o /usr/share/keyrings/mongodb-server-7.0.gpg --dearmor"
ssh user@your-vm 'echo "deb [ arch=amd64,arm64 signed-by=/usr/share/keyrings/mongodb-server-7.0.gpg ] \
  https://repo.mongodb.org/apt/ubuntu jammy/mongodb-org/7.0 multiverse" | \
  sudo tee /etc/apt/sources.list.d/mongodb-org-7.0.list'
ssh user@your-vm "sudo apt update && sudo apt install -y mongodb-org"

7. Configure Environment

# Copy example config
cp configs/.env.example configs/.env

# Edit configuration with MongoDB connection
vim configs/.env

# Example MongoDB URI:
# MONGODB_URI=mongodb://mongotron:password@your-vm.lan:27017/mongotron

8. Run

# Option A: Run locally
make run

# Option B: Run with Docker
make docker-run

# Option C: Run with Docker Compose
cd deployments/docker
docker-compose up -d

📚 Detailed Infrastructure Setup: See INFRASTRUCTURE.md for comprehensive production deployment guide including ZFS optimization, MongoDB configuration, and performance tuning.

Why Go Excels for MongoTron

1. Native Concurrency: Goroutines provide true lightweight threading with minimal overhead
2. Memory Efficiency: Superior garbage collection and memory management
3. Single Binary: Zero-dependency deployment simplifies operations
4. Network Performance: Optimized networking stack for high-throughput applications
5. Static Compilation: Eliminates runtime dependencies and version conflicts

Testing

MongoTron includes a comprehensive test suite to ensure reliability and maintainability.

Test Statistics

• Total Tests: 13 unit tests + 8+ integration tests
• Coverage: 38.1% (handlers), targeting 80%+
• Test Frameworks: Go testing, testify (mocking & assertions)

Quick Test Commands

# Run all unit tests
make test

# Run with verbose output
make test-verbose

# Generate coverage report
make test-coverage

# Run integration tests (requires running API server)
make test-integration

# Run benchmarks
make test-bench

Test Organization

mongotron/
├── internal/api/handlers/
│   ├── subscription_test.go    # 9 subscription handler tests
│   └── health_test.go          # 4 health check tests
└── test/integration/
    └── api_integration_test.go # 5 integration test suites

Unit Tests (13 tests)

Health Check Tests (4):

• Health endpoint validation
• Kubernetes readiness probe
• Kubernetes liveness probe
• Service unavailable handling

Subscription Handler Tests (9):

• Subscription creation (success & validation)
• Subscription retrieval (success & not found)
• Subscription listing (default & custom pagination)
• Subscription deletion (success & error handling)
• Advanced filtering support

Integration Tests (5 suites)

Full API Lifecycle:

1. Complete subscription flow (create → read → list → delete)
2. Error handling scenarios (validation, 404, 500)
3. Rate limiting validation (100 req/min)
4. Pagination with multiple subscriptions
5. Concurrent request handling (10 goroutines)

Running Tests

Unit Tests (fast, no external dependencies):

./run_tests.sh unit
# or
go test ./internal/api/handlers/...

Integration Tests (requires API server):

# Terminal 1: Start API server
./bin/mongotron-api

# Terminal 2: Run integration tests
./run_tests.sh integration
# or
go test ./test/integration/...

Coverage Report:

make test-coverage
open coverage.html

Writing Tests

MongoTron uses testify for mocking and assertions:

func TestExample(t *testing.T) {
    // Arrange
    mockManager := new(MockSubscriptionManager)
    mockManager.On("Subscribe", mock.Anything).Return(subscription, nil)
    
    // Act
    result := handler.CreateSubscription(req)
    
    // Assert
    assert.Equal(t, 200, result.StatusCode)
    mockManager.AssertExpectations(t)
}

For detailed testing documentation, see TEST_GUIDE.md.

Contributing

We welcome contributions to MongoTron! Please follow these guidelines:

Code Standards

• Formatting: Use gofmt and goimports for consistent formatting
• Linting: Code must pass golangci-lint with zero warnings
• Testing: Maintain >90% test coverage for all new code
• Documentation: Include godoc comments for all public functions and types

Development Workflow

1. Fork the repository and create a feature branch
2. Write tests for new functionality
3. Ensure all tests pass: make test
4. Run benchmarks for performance-critical changes: make benchmark
5. Submit a pull request with detailed description

Performance Requirements

• No performance regressions in core monitoring paths
• Memory usage must remain under 1KB per monitored address
• Event processing latency must stay sub-millisecond
