propagation**: Trace contexts are automatically propagated between client and server calls +- **Comprehensive tracing**: Both client and server interceptors capture request/response metadata +- **OpenTelemetry integration**: Uses standard OpenTelemetry libraries for compatibility +- **Error handling**: Automatically records errors and sets appropriate span status + +## Usage + +### Server Setup + +The main snapshotter service already includes tracing interceptors: + +```go +// Chain interceptors: tracing first, then request ID +interceptors := grpc.ChainUnaryInterceptor( + tracing.UnaryServerInterceptor(), + requestIDInterceptor, +) +srv := grpc.NewServer(interceptors) +``` + +Or use the convenience function: + +```go +srv := grpc.NewServer(tracing.WithServerTracing()) +``` + +### Client Setup + +For gRPC clients, add the tracing interceptor: + +```go +conn, err := grpc.DialContext(ctx, target, + grpc.WithUnaryInterceptor(tracing.UnaryClientInterceptor()), + // other options... +) +``` + +Or use the convenience function: + +```go +conn, err := grpc.DialContext(ctx, target, + tracing.WithClientTracing(), + // other options... +) +``` + +### Trace Propagation + +Trace IDs automatically propagate from: +1. **Incoming requests** → Server-side processing +2. **Server-side processing** → Outgoing client calls +3. **Client calls** → Downstream services + +Example flow: +``` +Client Request [trace-id: abc123] + ↓ +gRPC Server Interceptor [trace-id: abc123] + ↓ +Snapshotter Service [trace-id: abc123] + ↓ +Outgoing Client Call [trace-id: abc123] +``` + +## Trace Attributes + +The interceptors automatically add these attributes to spans: + +### Common Attributes +- `rpc.system`: "grpc" +- `rpc.service`: Service name (e.g., "containerd.services.snapshots.v1.Snapshots") +- `rpc.method`: Method name (e.g., "Prepare") +- `rpc.grpc.status_code`: gRPC status code +- `rpc.grpc.duration_ms`: Request duration in milliseconds + +### Error Handling +- Span status set to ERROR for failed requests +- Error details recorded in span +- gRPC status code captured + +## Configuration + +Set these environment variables for tracing: + +```bash +# Service name for traces +export OTEL_SERVICE_NAME="accelerated-container-image" + +# OTLP endpoint (e.g., Jaeger collector) +export OTEL_EXPORTER_OTLP_ENDPOINT="http://localhost:4317" + +# Environment tag +export ENVIRONMENT="production" +``` + +## Baggage API Usage + +The implementation includes full support for OpenTelemetry Baggage, allowing you to propagate key-value pairs across service boundaries. + +### Setting Baggage Values + +```go +import "github.com/containerd/accelerated-container-image/pkg/tracing" + +// Set individual values +ctx = tracing.SetRequestID(ctx, "req-12345") +ctx = tracing.SetUserID(ctx, "user-67890") +ctx = tracing.SetOperation(ctx, "prepare-snapshot") + +// Set image information +ctx = tracing.SetImageInfo(ctx, "alpine", "3.18") + +// Set multiple values at once +baggageMap := map[string]string{ + "environment": "production", + "namespace": "default", + "container.id": "container-123", +} +ctx = tracing.SetBaggageFromMap(ctx, baggageMap) +``` + +### Getting Baggage Values + +```go +// Get individual values +requestID := tracing.GetRequestID(ctx) +userID := tracing.GetUserID(ctx) +operation := tracing.GetOperation(ctx) + +// Get image information +imageName, imageTag := tracing.GetImageInfo(ctx) + +// Get all baggage as a map +allBaggage := tracing.GetBaggageAsMap(ctx) +``` + +### Automatic Baggage Propagation + +Baggage values are automatically: +1. **Extracted** from incoming gRPC metadata +2. **Injected** into outgoing gRPC metadata +3. **Added as span attributes** with `baggage.` prefix +4. **Propagated** through the entire request chain + +### Common Baggage Keys + +The package defines standard baggage keys: +- `request.id` - Request identifier +- `user.id` - User identifier +- `session.id` - Session identifier +- `operation` - Operation name +- `image.name` - Container image name +- `image.tag` - Container image tag +- `snapshot.key` - Snapshot key +- `container.id` - Container identifier +- `namespace` - Kubernetes namespace +- `environment` - Environment (prod, staging, etc.) + +## Integration with Request ID + +The request ID interceptor now uses baggage for propagation: + +```go +// Check if request ID exists in baggage (from upstream) +requestID := tracing.GetRequestID(ctx) +if requestID == "" { + // Generate new ID if not present + requestID = generateRequestID() + ctx = tracing.SetRequestID(ctx, requestID) +} +``` + +This ensures request IDs propagate across service boundaries while maintaining backward compatibility. + +## Integration with Existing Code + +The tracing is integrated with the existing snapshotter service: + +1. **Initialization**: `tracing.InitTracer()` sets up OpenTelemetry with baggage propagation +2. **Server interceptor**: Added to gRPC server chain, extracts baggage from metadata +3. **Service wrapper**: `tracing.WithTracing()` wraps the snapshotter service +4. **Client interceptor**: Added to any outgoing gRPC clients, injects baggage into metadata +5. **Baggage utilities**: Helper functions for common baggage operations + +This provides comprehensive tracing coverage at both the transport (gRPC) and application (snapshotter operations) levels, with full context propagation via baggage. \ No newline at end of file diff --git a/pkg/tracing/baggage.go b/pkg/tracing/baggage.go new file mode 100644 index
