<h1>集群安装方式对比</h1>
<p>kops 是官方出的 Kubernetes Operations，生产级 K8s 的安装、升级和管理。
可以看做是适用于集群的 kubectl，kops 可帮助您从命令行创建，销毁，升级和维护生产级，高可用性的 Kubernetes 集群。
目前正式支持AWS（Amazon Web Services），其中 GCE 和 OpenStack 处于 beta 测试阶段，而 VMware vSphere 处于 alpha 阶段，并且计划其他平台。
可见，它对云平台结合紧密而提供独特功能，如果未来预见只使用某个云平台，那么相比 kubespray 是更好的选择。
kubeadm 官方维护的为了给创建 Kubernetes 集群提供最佳实践的一个工具，涉及集群生命周期管理等知识。
通过 kubeadm 命令来管理，kubeadm < init | join | upgrade | reset >。
kubespray 是部署生产环境就绪的 Kubernetes 集群的工具。kubernetes-sigs 组织维护。
特点是通过 Ansible 部署，所以相比 kops 方式，kubespray 是 OS 级别通用的部署方式（可以是裸机或者云）。
另外 kubespray 2.8 以上版本推荐用 kubeadm 创建集群，以便从中使用生命周期管理的实践 并 卸载其中 OS 配置的东西。相当于结合了 kubeadm 以及自身的优点。
GitHub地址：https://github.com/kubernetes-sigs/kubespray
推荐使用kubespray2.8以上版本部署k8s集群。</p>
<h1>操作系统内核升级</h1>
<p>Docker对内核的要求
Note: If you use OverlayFS, use the overlay2 driver rather than the overlay driver, because it is more efficient in terms of inode utilization. To use the new driver, you need version 4.0 or higher of the Linux kernel, or RHEL or CentOS using version 3.10.0-514 and above.</p>
<p>For more information about differences between overlay vs overlay2, check Docker storage drivers.</p>
