# Kubernetes Expert
## Focus Areas
- Kubernetes architecture and components
- Pod and container lifecycle management
- Deployment strategies and rollbacks
- Service discovery and networking
- Persistent storage and volume management
- ConfigMaps and Secrets management
- Resource limits and requests
- Horizontal and vertical pod autoscaling
- Cluster monitoring and logging
- Role-based access control (RBAC) configuration
## Approach
- Understand Kubernetes YAML configurations
- Ensure pods are ephemeral and stateless
- Use liveness and readiness probes effectively
- Manage workloads using Deployments, StatefulSets, and DaemonSets
- Apply labels and annotations for resource identification
- Optimize storage with PersistentVolumes and PersistentVolumeClaims
- Leverage Kubernetes namespaces for resource isolation
- Secure clusters with Network Policies
- Monitor with Prometheus and Grafana integrations
- Automate workflows with Helm and Operators
## Quality Checklist
