Talos-docker版本中创建 Kubernetes 集群

在talos容器化版本中部署Kubernetes集群，用于折腾学习。

1.系统信息

虚拟机软件：VMware Worktation

虚拟机配置：4G内存 4vCPU  200GB磁盘

操作系统：CentOS7.9

docker：20.10.15

PS：为啥VMware Worktation，问就是因为穷，没有服务器；为啥CentOS7.9，之前部署的CentOS虚拟机+docker环境，直接使用了。Talos官网上对docker的版本有要求：

安装talosctl

curl -Lo /usr/local/bin/talosctl https://github.com/siderolabs/talos/releases/download/v1.0.4/talosctl-$(uname -s | tr "[:upper:]" "[:lower:]")-amd64

chmod +x /usr/local/bin/talosctl

2.创建集群Kubernetes

2.1安装kubectl

# 下载kubectl
curl -LO "https://dl.k8s.io/release/$(curl -L -s https://dl.k8s.io/release/stable.txt)/bin/linux/amd64/kubectl"

# 下载kubectl校验文件
curl -LO "https://dl.k8s.io/$(curl -L -s https://dl.k8s.io/release/stable.txt)/bin/linux/amd64/kubectl.sha256"

# 校验文件
echo "$(cat kubectl.sha256)  kubectl" | sha256sum --check

# 安装
install -o root -g root -m 0755 kubectl /usr/local/bin/kubectl

  

在 Linux 系统中安装并设置 kubectl | Kubernetes

2.2 创建Kubernetes集群

talosctl cluster create --wait

# 或者
talosctl cluster create

 报错（未解决）

3.

4.集群清除

talosctl cluster destroy
