云实例节点要求
云实例节点能够SSH远程连接上节点需要有sudo/curl/openssl/tar等相关命令。

设置云实例的安全组允许所有流量和端口通过【仅实验测试环境生产环境建议安装最小开放规则设置允许端口放行】。 如果您的网络配置使用防火墙规则或安全组请务必确保基础设施组件可以通过特定端口相互通信。建议您关闭防火墙。 请确保 /etc/resolv.conf 中的 DNS 地址可用否则可能会导致集群中的 DNS 出现问题。
$ sudo vim /etc/resolv.conf
$ sudo cat /etc/resolv.conf

nameserver 8.8.8.87. 下载KubeKey 您的集群必须有一个可用的容器运行时。如果您使用 KubeKey 搭建集群KubeKey 会默认安装最新版本的 Docker。或者您也可以在创建集群前手动安装 Docker 或其他容器运行时。 KubeKey 是用 Go 语言开发的一款全新的安装工具代替了以前基于 ansible 的安装程序。KubeKey 为用户提供了灵活的安装选择可以分别安装 KubeSphere 和 Kubernetes 或二者同时安装既方便又高效。 # 若访问Github/Googleapis受限先执行以下命令确保从正确的区域下载KubeKey。
export KKZONEcn# 再执行以下命令下载 KubeKey。
curl -sfL https://get-kk.kubesphere.io | VERSIONv3.0.13 sh -# 最后为下载下来的 kk 添加可执行权限。

只需执行一个命令即可进行安装其模板如下所示
./kk create cluster [--with-kubernetes version] [--with-kubesphere version]若要同时安装 Kubernetes 和 KubeSphere可参考以下示例命令
./kk create cluster --with-kubernetes v1.26.12 --with-kubesphere v3.4.0./kk create cluster --with-kubernetes v1.26.12 --with-kubesphere v3.4.0 --container-manager containerd -y执行该命令后KubeKey 将检查安装环境结果显示在一张表格中。输入 yes 继续安装流程。

Your Kubernetes control-plane has initialized successfully!To start using your cluster, you need to run the following as a regular user:mkdir -p $HOME/.kubesudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/configsudo chown $(id -u):$(id -g) $HOME/.kube/configAlternatively, if you are the root user, you can run:export KUBECONFIG/etc/kubernetes/admin.confYou should now deploy a pod network to the cluster.
Run kubectl apply -f [podnetwork].yaml with one of the options listed at:https://kubernetes.io/docs/concepts/cluster-administration/addons/You can now join any number of control-plane nodes by copying certificate authorities
and service account keys on each node and then running the following as root:kubeadm join lb.kubesphere.local:6443 --token qpnirw.gyfdxnceyth942i9 \--discovery-token-ca-cert-hash sha256:8f0739bdfa2fb5a6118b5b6d0e10985641aa7c903fd749e073caf718b350c282 \--control-planeThen you can join any number of worker nodes by running the following on each as root:kubeadm join lb.kubesphere.local:6443 --token qpnirw.gyfdxnceyth942i9 \--discovery-token-ca-cert-hash sha256:8f0739bdfa2fb5a6118b5b6d0e10985641aa7c903fd749e073caf718b350c282最后结果输出如下信息代表KubeSphere集群也已经安装完毕✅ [可选]单独安装Kubernetes
