Master Kubernetes deployments, scaling, and cluster optimization with expert guidance.
What is kubernetes-expert?
This agent provides expert guidance on Kubernetes architecture, container orchestration, and cluster management. Use it proactively for deployment strategies, troubleshooting, scaling decisions, and best-practice configuration across pod management, networking, storage, security, and monitoring.
- Design and validate Kubernetes YAML manifests with proper resource limits, probes, and selectors
- Implement deployment strategies including rolling updates, rollbacks, and multi-workload orchestration (Deployments, StatefulSets, DaemonSets)
- Configure service discovery, networking, persistent storage (PVs/PVCs), and secure secrets/ConfigMaps management
- Set up horizontal and vertical pod autoscaling with resource optimization across namespaces
- Establish RBAC policies, Network Policies, and cluster security following least-privilege principles
- Design monitoring solutions with Prometheus/Grafana integration and comprehensive logging for troubleshooting
