Core Kubernetes Resources

Manage fundamental Kubernetes objects using kubectl-mcp-server's core tools.

When to Apply

Use this skill when:

• User mentions: "pods", "namespaces", "configmaps", "secrets", "nodes", "events"
• Operations: listing resources, describing objects, creating/deleting resources
• Keywords: "show me", "list", "get", "describe", "create", "delete"

Priority Rules

| Priority | Rule | Impact | Tools | |----------|------|--------|-------| | 1 | Check namespace exists before operations | CRITICAL | get_namespaces | | 2 | Never expose secrets in plain text | CRITICAL | Handle get_secret output carefully | | 3 | Use labels for filtering | HIGH | label_selector parameter | | 4 | Check events after changes | MEDIUM | get_events |

Quick Reference

| Task | Tool | Example | |------|------|---------| | List pods | get_pods | get_pods(namespace="default") | | Describe pod | describe_pod | describe_pod(name, namespace) | | Get logs | get_pod_logs | get_pod_logs(name, namespace) | | List namespaces | get_namespaces | get_namespaces() | | Get configmap | get_configmap | get_configmap(name, namespace) | | List nodes | get_nodes | get_nodes() |

Pods

get_pods(namespace="default")
get_pods(namespace="kube-system", label_selector="app=nginx")

describe_pod(name="my-pod", namespace="default")

get_pod_logs(name="my-pod", namespace="default")
get_pod_logs(name="my-pod", namespace="default", previous=True)

delete_pod(name="my-pod", namespace="default")

Namespaces

get_namespaces()

create_namespace(name="my-namespace")

delete_namespace(name="my-namespace")

ConfigMaps

get_configmaps(namespace="default")

get_configmap(name="my-config", namespace="default")

create_configmap(
    name="app-config",
    namespace="default",
    data={"key": "value", "config.yaml": "setting: true"}
)

Secrets

get_secrets(namespace="default")

get_secret(name="my-secret", namespace="default")

create_secret(
    name="db-credentials",
    namespace="default",
    data={"username": "admin", "password": "secret123"}
)

Nodes

get_nodes()

describe_node(name="node-1")

get_nodes_summary()

cordon_node(name="node-1")
uncordon_node(name="node-1")

drain_node(name="node-1", ignore_daemonsets=True)

Events

get_events(namespace="default")

get_events(namespace="default", field_selector="involvedObject.name=my-pod")

Multi-Cluster Support

All tools support context parameter:

get_pods(namespace="default", context="production-cluster")
get_nodes(context="staging-cluster")
