KubeSphere核心实战_在Centos7.9使用kubekey一键构建k8s集群完整平台_多节点自动化部署kubesphere_k8s集群---分布式云原生部署架构搭建039
以下是使用KubeKey一键构建KubeSphere多节点Kubernetes集群的步骤和示例代码:
- 安装KubeKey:
export KKZONE=cn
curl -sfL https://get-kk.kubesphere.io | sh -
- 创建配置文件
config-sample.yaml
,并编辑以下内容:
apiVersion: kubekey.kubesphere.io/v1alpha1
kind: Cluster
metadata:
name: sample
spec:
hosts:
- {name: node1, address: "192.168.0.1", internalAddress: "192.168.0.1", user: root, password: Qcloud@123}
- {name: node2, address: "192.168.0.2", internalAddress: "192.168.0.2", user: root, password: Qcloud@123}
- {name: node3, address: "192.168.0.3", internalAddress: "192.168.0.3", user: root, password: Qcloud@123}
roleGroups:
etcd:
- node1
- node2
- node3
master:
- node1
- node2
worker:
- node1
- node2
- node3
controlPlaneEndpoint: "192.168.0.1:6443"
kubernetes:
version: v1.17.9
clusterName: cluster.local
network:
plugin: calico
kubePodsCIDR: 10.233.64.0/18
kubeServiceCIDR: 10.233.0.0/18
addons:
[]
- 使用KubeKey部署集群:
./kk create cluster -f config-sample.yaml
请根据您的实际网络环境和服务器配置调整上述配置文件。这个过程可能需要一些时间,因为它会下载相关的Docker镜像并在每个节点上安装Kubernetes集群。
注意:在实际操作中,请确保所有节点的时间同步、网络配置(包括防火墙规则、swap分区等)正确无误,并且确保SSH免密登录已经设置好,以便KubeKey能够无缝地在各个节点上执行安装。
