要在Woker节点上安装k3s,我们应该将K3S_URL以及K3S_TOKEN或K3S_CLUSTER_SECRET环境变量一起传递。 K3S_TOKEN在第一个节点k3s-master上的/var/lib/rancher/k3s/server/node-token中创建. [root@k3s-master~]# cat /var/lib/rancher/k3s/server/node-token K10a3faef2c7c35eae8a485434cd2e13fa122ba11f96dd2c815...

The binary, which contains all the non-containerized components needed to run a cluster, is smaller The memory footprint is reduced primarily by running many components inside of a single process. This eliminates significant overhead that would otherwise be duplicated for each component. ...

client—>node ip:port—>service ip:port—>pod ip:port。 采用NodePort方式暴露服务面临的问题是,服务一旦多起来,NodePort在每个节点上开启的端口会及其庞大,而且难以维护;而使用 DaemonSet 在每个Node上监听 80的nginx反向代理又有域名分配及动态更新问题,此时Ingress出现了。
检查:yarn cluster --list-node-labels 给节点增加标签 yarn rmadmin -replaceLabelsOnNode "node1[:port]=label1 node2=label2" 如果没有指定port,则会为默认为该实例上所有Nodemanager打上相同标签 3,给节点标签配置调度器。 配置样例: 假如当前的队列结构为: ...
