StatefulSets StatefulSet is the workload API object used to manage stateful applications. Note: StatefulSets are stable (GA) in 1.9. Manages the deployment and scaling of a set of Pods, and provides guarantees about the ordering and uniqueness of the…
  Deployments A Deployment controller provides declarative updates for Pods and ReplicaSets. You describe a desired state in a Deployment object, and the Deployment controller changes the actual state to the desired state at a controlled rate. You ca…
ReplicaSet is the next-generation Replication Controller. The only difference between a ReplicaSet and a Replication Controller right now is the selector support. ReplicaSet supports the new set-based selector requirements as described in the labels…

一 部署高可用kube-controller-manager 1.1 高可用kube-controller-manager介绍 本实验部署一个三实例 kube-controller-manager 的集群,启动后将通过竞争选举机制产生一个 leader 节点,其它节点为阻塞状态.当 leader 节点不可用时,阻塞的节点将再次进行选举产生新的 leader 节点,从而保证服务的可用性. 为保证通信安全,本文档先生成 x509 证书和私钥,kube-controller-manager 在如下两种…

你有了解过Kubernetes的认证授权链路吗?是否对TKE的权限控制CAM策略.服务角色傻傻分不清楚?本文将会向你介绍腾讯云TKE平台侧的访问控制.Kubernetes访问控制链路,以及演示如何将平台侧账号对接到Kubernetes内. 当你在使用腾讯云容器服务TKE(Tencent Kubernetes Engine)的时候,如果多人共用一个账号的情况下,是否有遇到以下问题呢? 密钥由多人共享,泄密风险高. 无法限制其他人的访问权限,其他人误操作易造成安全风险. 为了解决以上问题,腾讯云CA…
BACKGROUND admission controllers的特点: 可定制性:准入功能可针对不同的场景进行调整. 可预防性:审计则是为了检测问题,而准入控制器可以预防问题发生 可扩展性:在kubernetes自有的验证机制外,增加了另外的防线,弥补了RBAC仅能对资源提供安全保证. 下图,显示了用户操作资源的流程,可以看出 admission controllers 作用是在通过身份验证资源持久化之前起到拦截作用.在准入控制器的加入会使kubernetes增加了更高级的安全功能. 图:Ku…

目前kubevirt提供虚机管理的功能. kill, delete, shutdown, migration 等. VMI是virtual machine interface的缩写. SyncVMI,实际上就是创建一个VM. 创建VM的map, 支持PCI设备. 只是libvirt的一层皮,libvirt有啥它就支持啥. 连package的名字都叫virtwrap handler的调用launcher. LauncherClient(RPC)提供给handler的几个功能.    这个handl…
