Generic Cluster Manager (`scripts/cluster_manager.sh`) +### Unified CLI Implementation +- **Main CLI**: `cmd/pickbox/main.go` - Unified command-line interface +- **Node Management**: `cmd/pickbox/node.go` - Node lifecycle management +- **Multi-Replication**: `cmd/pickbox/multi_replication.go` - Multi-directional replication logic +- **Cluster Management**: `cmd/pickbox/cluster.go` - Cluster operations -**New Features:** -- Supports 1 to 20+ nodes (configurable) -- Parameterized port assignments -- Configuration file support -- Dynamic node discovery -- Comprehensive cluster management (start, stop, restart, status, clean, logs) - -**Usage Examples:** +### Binary Usage ```bash -# Start 5-node cluster -./scripts/cluster_manager.sh start -n 5 +# Build the unified binary +go build -o bin/pickbox ./cmd/pickbox -# Start 7-node cluster with custom ports -./scripts/cluster_manager.sh start -n 7 -p 9000 -a 10000 - -# Use configuration file -./scripts/cluster_manager.sh start -c examples/cluster-configs/5-node-cluster.conf - -# Check cluster status -./scripts/cluster_manager.sh status -n 5 - -# View logs from all nodes -./scripts/cluster_manager.sh logs -n 5 -``` - -### 2. Enhanced Node Addition (`scripts/add_nodes.go`) - -**Improvements:** -- Generic node count parameter (`-nodes N`) -- Configurable port ranges (`-base-port P`) -- Flexible starting node number (`-start N`) -- Support for remote clusters (`-host H`) - -**Usage Examples:** -```bash -# Add 2 nodes (default: node2, node3) -go run scripts/add_nodes.go - -# Add 5 nodes starting from node2 -go run scripts/add_nodes.go -nodes 5 - -# Add nodes to cluster with custom ports -go run scripts/add_nodes.go -nodes 3 -base-port 9000 -admin-port 10000 - -# Add nodes starting from node4 (for expanding clusters) -go run scripts/add_nodes.go -nodes 2 -start 4 +# Start nodes using the CLI +./bin/pickbox node multi --node-id node1 --port 8001 --bootstrap +./bin/pickbox node multi --node-id node2 --port 8002 --join 127.0.0.1:8001 +./bin/pickbox node multi --node-id node3 --port 8003 --join 127.0.0.1:8001 ``` -### 3. Flexible Main Application (`cmd/multi_replication/main.go`) +## Implementation Components -**Key Change:** -- Removed hardcoded "node1" bootstrap assumption -- Any node can bootstrap when no join address is specified -- More flexible cluster initialization - -**Before:** +### 1. **Port Allocation System** ```go -// Auto-bootstrap if no join address and this is node1 -if cfg.JoinAddr == "" && cfg.NodeID == "node1" { - cfg.BootstrapCluster = true +// Port calculation logic in cmd/pickbox/ +func calculatePorts(basePort int) (int, int, int) { + raftPort := basePort + adminPort := basePort + 1000 + monitorPort := basePort + 2000 + return raftPort, adminPort, monitorPort } ``` -**After:** +### 2. **Configuration Management** ```go -// Auto-bootstrap if no join address is specified -// This allows any node to bootstrap when it's the first in the cluster -if cfg.JoinAddr == "" { - cfg.BootstrapCluster = true +// Enhanced configuration in cmd/pickbox/multi_replication.go +type MultiConfig struct { + NodeID string + Port int + AdminPort int + MonitorPort int + DashboardPort int + DataDir string + Join string + Host string + Bootstrap bool } ``` -### 4. Generic Test Suite (`scripts/tests/test_n_replication.sh`) - -**Features:** -- Tests any number of nodes -- Configurable timeouts and ports -- Comprehensive validation (file operations, deduplication, consistency) -- Verbose output support +### 3. **Cluster Management Scripts** +The `scripts/cluster_manager.sh` script provides comprehensive N-node cluster management: -**Usage Examples:** -```bash -# Test 5-node cluster -./scripts/tests/test_n_replication.sh -n 5 - -# Test with custom configuration -./scripts/tests/test_n_replication.sh -n 7 -p 9000 -a 10000 -v - -# Quick test with timeout -./scripts/tests/test_n_replication.sh -n 4 -t 120 -``` - -### 5.
