Pod其实有两种类型:普通的Pod及静态Pod(static Pod),后者比较特殊,它并不存放在Kubernetes的etcd存储里,而是存放在某个具体的Node上的一个具体文件中,并且只在此Node上启动运行。而普通的Pod一旦被创建,就会被放入到etcd中存储,随后会被Kubernetes Master调度到某个具体的Node上并进行绑定(Binding),随后该Pod被对应的...
1.8版本之前.开启rbac后,apiserver默认绑定system:nodes组到system:node的clusterrole。v1.8之后,此绑定默认不存在,需要手工绑定,否则kubelet启动后会报认证错误,使用kubectl get nodes查看无法成为Ready状态 原因:kubelet-bootstrap并没有权限创建证书。所以要创建这个用户的权限并绑定到这个角色上 解决 查看系统中的角色与...
