Kubernetes Skill

Comprehensive Kubernetes cluster management through native kubectl execution. This skill provides 18+ kubectl tools for managing your clusters.

When to Use

• Managing Kubernetes resources (pods, deployments, services, configmaps, secrets)
• Viewing pod logs and debugging containers
• Scaling deployments up or down
• Managing cluster configuration and contexts
• Performing rollout operations (restart, undo, status)
• Node management (cordon, uncordon, drain, taint)
• Creating and deleting resources

Requirements

• kubectl must be installed and in PATH
• Valid kubeconfig (default: ~/.kube/config or KUBECONFIG env var)
• Appropriate cluster access permissions

Configuration

This skill uses your existing kubectl configuration. No additional configuration is required.

To use a specific kubeconfig:

export KUBECONFIG=/path/to/kubeconfig

Or configure in .skill-engine.toml:

[skills.kubernetes.instances.prod]
config.kubeconfig = "${KUBECONFIG:-~/.kube/config}"

Security Notes

• This skill executes real kubectl commands against your cluster
• Commands are validated against an allowlist (kubectl, helm, etc.)
• Ensure your kubeconfig has appropriate permissions
• Be cautious with delete and drain operations
