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

Priority Rule Impact Tools

1 Detect kind CLI first CRITICAL kind_detect_tool

2 Generate config for complex setups HIGH kind_config_generate_tool

3 Load images after cluster creation HIGH kind_load_image_tool

4 Export logs for debugging MEDIUM kind_export_logs_tool

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)

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

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

Restart Node

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 """)

Development with Local Registry

kind_registry_create_tool()

config = kind_config_generate_tool(workers=1, ingress=True, registry=True)

kind vs vind (vCluster)

Feature kind vind (vCluster)

Purpose Local dev/CI clusters Virtual clusters in existing K8s

Isolation Full clusters in Docker Virtual namespaces with isolation

Resource Usage Higher (full cluster) Lower (shares host cluster)

Best For Local testing, CI/CD Multi-tenancy, dev environments

Requires Docker Existing K8s cluster
