opscart/opscart-k8s-watcher v0.2

v0.2: Multi-Cluster Support

on GitHub

🎉 Multi-Cluster Support

v0.2 adds the ability to scan, compare, and analyze multiple Kubernetes clusters simultaneously.

✨ New Features

• Config management - Centralized cluster configuration (config init, config show)
• Multi-cluster scanning - Scan all clusters with --all-clusters
• Cluster groups - Scan by environment with --cluster-group production
• Side-by-side comparison - Compare security posture with --compare=a,b
• Sequential execution - Clear, readable output for multiple clusters
• Cluster identification - Every scan shows which cluster it's analyzing

🚀 Usage

# Initialize config
./opscart-scan config init

# Scan all clusters
./opscart-scan security --all-clusters

# Scan by group
./opscart-scan resources --cluster-group production

# Compare two clusters
./opscart-scan security --compare=prod,staging

🔍 Real-World Findings During Testing

• Found production namespace idle for 70+ days
• Found staging namespace idle for 21+ days
• Identified spot instance optimization opportunities across clusters
• Scan time: ~200ms per cluster (sequential)

Backward Compatibility

100% compatible with v0.1 - All existing commands work unchanged

Installation

git clone https://github.com/opscart/opscart-k8s-watcher.git
cd opscart-k8s-watcher
git checkout v0.2
go build -o opscart-scan cmd/opscart-scan/main.go
./opscart-scan config init

What's Next (v0.3)

• HTML report generation
• JSON/CSV output formats
• Full diff view for cluster comparison
• Network policy detection

🐛 Known Issues

• Compare mode currently only works with comma-separated format: --compare=a,b
• Multi-cluster comparison limited to security command (other commands in v0.3)
