通过 homeland-docker 方式更新的

想进入 console 界面进行

irb> Setting.where(thing_type: "User")
irb> Setting.where(thing_type: "User").delete_all

出现了以下错误

推荐一个工具：使用 kainstall 工具一键部署 kubernetes (k8s) 高可用集群

lework — Thu, 12 Nov 2020 15:45:24 +0800

介绍

kainstall = kubeadm install kubernetes

使用 shell 脚本，基于 kubeadm 一键部署 kubernetes HA 集群，轻松帮您打造一个可在 生产环境 下使用的健壮集群。

https://github.com/lework/kainstall

为什么？

为什么要搞这个？Ansible PlayBook 不好么？

因为懒，Ansible PlayBook 编排是非常给力的，不过需要安装 Python 和 Ansible, 且需要下载多个 yaml 文件。因为懒，我想要个更简单的方式来快速部署一个分布式的 Kubernetes HA 集群，使用 shell 脚本可以不借助外力直接在服务器上运行，省时省力。并且 shell 脚本只有一个文件，文件大小100 KB 左右，非常小巧，可以实现一条命令安装集群的超快体验，而且配合离线安装包，可以在不联网的环境下安装集群，这体验真的非常爽啊。
