以 docker 方式安装
docker run -d –restart=unless-stopped -p 8088:80 -p 8443:443 rancher/rancher:latest

常用脚本

docker stop $(docker ps -q) & docker rm $(docker ps -aq)

umount $(df -HT | grep '/var/lib/kubelet/pods' | awk '{print $7}')

# cat cleank8s.sh
#!/bin/sh
docker rm -f $(docker ps -qa)
docker volume rm $(docker volume ls -q)
cleanupdirs="/var/lib/etcd* /etc/kubernete* /etc/cni* /opt/cni* /var/lib/cni* /var/run/calico* /var/lib/kubelet*"
for dir in $cleanupdirs; do
  echo "Removing $dir"
  rm -Rf $dir
done
