K8S Kind

kind (Kubernetes IN Docker) Management

Manage local Kubernetes clusters using kubectl-mcp-server's kind tools (32 tools).

kind enables running local Kubernetes clusters using Docker container "nodes". It's ideal for local development, CI/CD testing, and testing across Kubernetes versions.

When to Apply

Use this skill when:

• User mentions: "kind", "local cluster", "Kubernetes in Docker", "dev cluster"
• Operations: creating local clusters, loading images, CI/CD testing
• Keywords: "local development", "test cluster", "load image", "multi-node"

Priority Rules

Quick Reference

Prerequisites

• kind CLI: Required for all kind tools

  # macOS
  brew install kind
  # or download binary
  curl -Lo ./kind https://kind.sigs.k8s.io/dl/latest/kind-$(uname)-amd64
  chmod +x ./kind && sudo mv ./kind /usr/local/bin/kind
  

• Docker: Required (kind runs clusters in Docker containers)

Check Installation

kind_detect_tool()

kind_version_tool()

kind_provider_info_tool()

List Clusters

kind_list_clusters_tool()

Get Cluster Information

kind_cluster_info_tool(name="my-cluster")

kind_cluster_status_tool(name="my-cluster")

kind_get_nodes_tool(name="my-cluster")

kind_node_labels_tool(name="my-cluster")

Configuration Management

Generate Config

kind_config_generate_tool()

kind_config_generate_tool(workers=2, control_planes=1)

kind_config_generate_tool(workers=2, ingress=True, registry=True)

Cluster Lifecycle

Create Cluster

kind_create_cluster_tool()

kind_create_cluster_tool(name="dev-cluster")

kind_create_cluster_tool(
    name="v129-cluster",
    image="kindest/node:v1.29.0"
)

kind_create_cluster_tool(
    name="multi-node",
    config="kind-config.yaml"
)

Multi-Node Config Example

Create a file kind-config.yaml:

kind: Cluster
apiVersion: kind.x-k8s.io/v1alpha4
nodes:
- role: control-plane
  extraPortMappings:
  - containerPort: 30000
    hostPort: 30000
    protocol: TCP
- role: worker
- role: worker

Delete Cluster

kind_delete_cluster_tool(name="dev-cluster")

kind_delete_all_clusters_tool()

Local Registry Integration

Create Registry

kind_registry_create_tool()

kind_registry_create_tool(name="my-registry", port=5001)

Connect Cluster to Registry

kind_registry_connect_tool(cluster_name="my-cluster")

Check Registry Status

kind_registry_status_tool()

Registry Workflow

kind_registry_create_tool()

config = kind_config_generate_tool(registry=True)

kind_create_cluster_tool(name="dev", config="/tmp/kind.yaml")

kind_registry_connect_tool(cluster_name="dev")

Image Loading (Key Feature!)

The ability to load local Docker images directly into kind clusters is one of its most powerful features for local development.

Load Docker Images

kind_load_image_tool(images="myapp:latest", name="my-cluster")

kind_load_image_tool(
    images="myapp:latest,mydb:latest,myweb:v1",
    name="my-cluster"
)

Load from Archive

kind_load_image_archive_tool(
    archive="/path/to/images.tar",
    name="my-cluster"
)

List Images on Cluster

kind_images_list_tool(cluster="my-cluster")

kind_images_list_tool(cluster="my-cluster", node="my-cluster-worker")

Node Management

Inspect Node

kind_node_inspect_tool(node="kind-control-plane")

Get Node Logs

kind_node_logs_tool(node="kind-control-plane")

kind_node_logs_tool(node="kind-control-plane", tail=200)

Execute Command on Node

kind_node_exec_tool(
    node="kind-control-plane",
    command="crictl images"
)

kind_node_exec_tool(
    node="kind-control-plane",
    command="journalctl -u kubelet --no-pager -n 50"
)

Restart Node

kind_node_restart_tool(node="kind-worker")

Networking

Inspect Network

kind_network_inspect_tool()

List Port Mappings

kind_port_mappings_tool(cluster="my-cluster")

Setup Ingress

kind_ingress_setup_tool(cluster="my-cluster")

kind_ingress_setup_tool(cluster="my-cluster", ingress_type="contour")

Advanced: Build Node Image

Build custom node images from Kubernetes source:

kind_build_node_image_tool()

kind_build_node_image_tool(
    image="my-custom-node:v1.30.0",
    kube_root="/path/to/kubernetes"
)

Update Kubeconfig

kind_set_kubeconfig_tool(name="my-cluster")

Development Workflow

Quick Local Development

kind_create_cluster_tool(name="dev")

kind_load_image_tool(images="myapp:dev", name="dev")

kubectl_apply(manifest="""
apiVersion: apps/v1
kind: Deployment
metadata:
  name: myapp
spec:
  replicas: 1
  selector:
    matchLabels:
      app: myapp
  template:
    metadata:
      labels:
        app: myapp
    spec:
      containers:
      - name: myapp
        image: myapp:dev
        imagePullPolicy: Never
""")
