多 NUMA 结构下,为了保证效率,所以会按内存和 CPU 的相对距离来按 node 定义是否为 local memory 或者说本地内存,同时由于实际位置不同,所以就可能会产生内存分配不均匀的情况了。比如,我们可以使用 numactl 管理工具查看下当前机器上的情况: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 [tao@moelove~]#...

设置Host name,这里为了方便区分master和node,将两台虚拟机分别设置为k8s-master和k8s-node1,后续可以增加node2,node3….…→选择网卡enp0s3,这里需要对Host Only网卡进行配置,点击Configure…,点击IPv4 Settings,修改Method为Manual手动,添加一个Address设置ip地址,子网掩码和网关,子网掩码和网关需和上一步中主机上面...
4、配置每个pod的nodeSelector,指定该pod安装到集群的哪个节点上,这步非常重要,官方的配置是没写这个的,没配置的话后面会出问题;nodeSelector是通过节点的label来选定的,所以上一小节的步骤对该配置是必要的。 部署FATE集群 如果一切没有问题,那就可以使用kubefate cluster install来部署两个fate集群了,(没遇到坑的...
Master和Node在访问ECR(镜像仓库)、EBS 和 EFS 时需要具有的相应的权限,为此要创建一个统一的IAM Role关联到Kubernetes集群上的所有节点。请在一台具有创建IAM Role权限的EC2上执行下列命令,也可用通过图形界面来进行创建。 6.1 创建角色Amazon_k8s(在Mgmt节点执行以下命令) ...

Restarting node can recover it. But we still have the following questions: Why is “kubectl exec” causing problems? This looks like a bug: if the API is not designed to handle some load, we expect it to return an error, not hang. ...
