运行kubelet standalone模式

下载kubelet二进制包

# curl -L --remote-name-all https://storage.googleapis.com/kubernetes-release/release/${RELEASE}/bin/linux/amd64/kubelet
# chmod +x kubelet

启动kubelet

# kubelet --cgroup-driver=systemd --pod-manifest-path=/home --allow-privileged=true -v 2 --fail-swap-on=false --pod-infra-container-image=registry.cn-hangzhou.aliyuncs.com/zhangoic/pause-amd64:3.0

运行一个静态pod

在/home路径下增加一个pod的配置文件

# cat static-web.yaml 
apiVersion: v1
kind: Pod
metadata:
  name: static-web
  labels:
    role: myrole
spec:
  containers:
    - name: web
      image: nginx
      ports:
        - name: web
          containerPort: 80
          protocol: TCP

使用docker ps查看容器

# docker ps -a|grep static

kubelet standalone不需要和apiserver交互，因此可以帮助我们更便捷的调试、研究kubelet原理。
