注意:

    此操作不可逆，如有需要请做好备份操作。此删除方式将会删除部署的所有组件。避免其他因素导致卸载不干净，建议先把应用全部停止完成。管理节点卸载可能会导致计算节点不可用。

    以下卸载仅面向管理节点和计算节点复用情况，其他情况类似

    1. # 计算节点需要下线后操作删除
    3. grclis stop
    5. systemctl disable docker
    6. systemctl disable etcd
    7. systemctl disable node
    8. systemctl disable calico
    9. systemctl disable salt-master
    10. systemctl disable salt-minion
    11. systemctl disable kube-apiserver
    12. systemctl disable kube-controller-manager
    13. systemctl disable kube-scheduler
    14. systemctl disable kubelet
    16. cd /etc/systemd/system/
    17. systemctl disable rbd-*
    19. cclear
    21. systemctl stop docker
    22. systemctl stop salt-master
    23. systemctl stop salt-minion
    25. yum remove -y gr-docker*
    26. yum remove -y salt-*
    28. rm -rf /etc/systemd/system/kube-*
    29. rm -rf /etc/systemd/system/rbd-*
    30. rm -rf /etc/systemd/system/kubelet*
    31. rm -rf /etc/systemd/system/node.service
    32. rm -rf /etc/systemd/system/etcd.service
    33. rm -rf /etc/systemd/system/calico.service
    34. rm -rf /usr/lib/systemd/system/docker.service
    36. rm -rf /opt/rainbond
    37. rm -rf /cache
    38. rm -rf /grdata/
    39. rm -rf /etc/goodrain/
    40. rm -rf /srv/
    41. rm -rf /etc/salt/*
    43. cat > /etc/hosts <<EOF
    44. 127.0.0.1 localhost
    45. EOF
    47. # /usr/local/bin/
    48. 可以根据需求删除：calicoctl  ctop  dc-compose  docker-compose  domain-cli  etcdctl  grcert  grctl  kubectl  kubelet  node  scope  yq
