一个Kubernetes集群是由一组被称作节点(Node)的机器组成,这些节点上会运行由Kubernetes所管理的所有资源。 Kubernetes集群中核心组件有:Control Plane(控制面板)组件、Kubelet组件和Kube-proxy组件。通常情况下,我们称部署Control Plane组件的节点为Master Node(主节点),称部署Kubelet组件和Kube-proxy组件的节点为Worker Node...
我们现在可以使用kubeconfig文件并验证集群是否启动并运行: ~/kube1 $exportKUBECONFIG=$PWD/kube_config_cluster.yml~/kube1 $ kubectl get nodeskubectl get nodesNAME STATUS ROLES AGE VERSION209.97.129.73 Ready controlplane,etcd,worker 4m26s v1.17.6 集群仅包括一个节点,显然不是生产级的集群,但对于本文...
As a safeguard, uploaded-certs will be deleted in two hours; If necessary, you can use "kubeadm init phase upload-certs --upload-certs" to reload certs afterward. Then you can join any number of worker nodes by running the following on each as root: kubeadm join 10.0.0.99:6443 --token...

前面的高可用集群的etcd是与control plane部署在同一个节点上的,两者会相互影响,etcd还有一种部署方式是与control plane分离部署,提供更高的稳定性。 这里部署一个3节点的etcd集群,然后使用外置的etcd集群创建k8s集群。 节点 IP 备注 etcd01 10.0.0.16 etcd01节点 etcd02 10.0.0.17 etcd02节点 etcd03 10.0... ...

Set up an RKE1 cluster with 3 control plane + etcd nodes (using 3 etcd-only nodes should also work, but I reproduced the issue with cp+etcd nodes) and 1 worker node. Remove one etcd node (removal via the UI should yield the same results as removing it through the cluster.yml file;...
