Restart minikube

minikube stop && minikube start

Add alias

alias kubectl="minikube kubectl --"

FAQ

通常是由于 Metrics Server 未正确安装 或 External Metrics API 缺失 导致的

# 启用 Minikube 的 metrics-server 插件
minikube addons enable metrics-server

# 等待部署完成（约 1-2 分钟）
kubectl wait --for=condition=available deployment/metrics-server -n kube-system --timeout=180s

# 验证 Metrics Server 是否运行
kubectl -n kube-system get pods  | grep metrics-server

the possibilities are endless (almost - including other shortcodes may or may not work)

You can add standard markdown syntax:

  • multiple paragraphs
  • bullet point lists
  • emphasized, bold and even bold emphasized text
  • links
  • etc.
...and even source code
