Cloud Native Getting Started: Build a Local Kubernetes Testing Environment in 3 Steps

For developers new to cloud-native technologies, setting up a stable local K8s environment is the first step to getting started. This article implements rapid deployment based on Docker + Kind, requiring no complex hardware configurations, and is suitable for beginners to learn and test.

I. Environment Preparation

#

• Prerequisite: Docker installed (version 20.10+)
• Install Kind: curl -Lo ./kind https://kind.sigs.k8s.io/dl/v0.20.0/kind-linux-amd64 && chmod +x ./kind && sudo mv ./kind /usr/local/bin/

II. Build K8s Cluster in 3 Steps

#

1. Create Cluster Configuration File Create kind-config.yaml:

kind: Cluster
apiVersion: kind.x-k8s.io/v1alpha4
nodes:
- role: control-plane
  extraPortMappings:
  - containerPort: 80
    hostPort: 80
    protocol: TCP
