RKE2+ubuntu20.04TSL快速部署k8s集群

1. 获取 rke2 安装程序

   curl -sfL https://rancher-mirror.rancher.cn/rke2/install.sh | INSTALL_RKE2_MIRROR=cn sh -
   或者
   curl -sfL https://get.rke2.io | sh -
   

2. 创建自定义配置文件

   mkdir -p /etc/rancher/rke2
   vim /etc/rancher/rke2/config.yaml
   

   内容如下：

   token: demo-server
   node-name: demo-server-node
   tls-san: 192.168.100.136 #启动机器的ip
   system-default-registry: "registry.aliyuncs.com"
   

3. 启动 rke2-server 服务

   systemctl enable rke2-server.service
   systemctl start rke2-server.service
   

4. 添加环境变量

   cd /etc/profile.d
   vim k8s.sh
   

   将以下写入文件

   export KUBECONFIG=/etc/rancher/rke2/rke2.yaml PATH=$PATH:/var/lib/rancher/rke2/bin
   

5. 下载 helm, 移动到 /var/lib/rancher/rke2/bin 目录下

   mv helm /var/lib/rancher/rke2/bin/
   

6. 查看当前集群节点

   kubectl get no
   

7. 添加 repo

   helm repo add bitnami https://charts.bitnami.com/bitnami
