kubspray使用,kubespary优化download过程

ubuntu安装k8s二进制文件

# 更新包列表并安装 HTTPS 支持
sudo apt-get update && sudo apt-get install -y apt-transport-https

# 创建 keyrings 目录（若已存在不会报错）
sudo mkdir -p /etc/apt/keyrings

# 下载并添加阿里云 Kubernetes 镜像的 GPG 密钥
curl -fsSL https://mirrors.aliyun.com/kubernetes-new/core/stable/v1.28/deb/Release.key | sudo gpg --dearmor -o /etc/apt/keyrings/kubernetes-apt-keyring.gpg

# 添加 Kubernetes 阿里云镜像源
echo "deb [signed-by=/etc/apt/keyrings/kubernetes-apt-keyring.gpg] https://mirrors.aliyun.com/kubernetes-new/core/stable/v1.28/deb/ /" | sudo tee /etc/apt/sources.list.d/kubernetes.list

# 再次更新包列表以从新添加的 Kubernetes 源中获取信息
sudo apt-get update

# 安装 kubelet、kubeadm 和 kubectl
sudo apt-get install -y kubelet kubeadm kubectl

# 锁定版本，防止自动升级
sudo apt-mark hold kubelet kubeadm kubectl

镜像镜像转移到阿里云

image.sh

kubeadm config images list | grep k8s | while read image; do
  # 从 image 中提取镜像名称和标签
  image_name=$(echo $image | sed -E 's#(.*)/([^:]+):(.*)#\2:\3#')
  tag=$(echo $image | sed -E 's#(.*)/([^:]+):(.*)#\3#')
  
  # 拼接新的镜像地址
  new_image="registry.cn-hangzhou.aliyuncs.com/k8s-a/$image_name"
  
  # 检查该镜像是否已经存在本地
  if ! docker images | grep -q "$new_image"; then
    echo "Pushing image: $new_image"
    docker push "$new_image"
  else
    echo "Image $new_image already exists locally, skipping push."
  fi
done

sh image.sh

从阿里云同步镜像到harbor

1. 点击仓库管理,点击新建目标,
2. 提供者,选择Alibaba ACR,目标名,k8s-a(自己定义),目标URL,https://registry.cn-hangzhou.aliyuncs.com,访问ID,访问密码,对应阿里云的RAM访问的AccessKey
3. 点击测试连接
4. 点击复制管理,点击新建规则,
5. 名称,k8s-a,复制模式,选择Pull-based,源仓库,k8s-a-https://registry.cn-hangzhou.aliyuncs.com,触发模式,手动,点击保存
6. 选中k8s-a规则左侧圆点,点击复制,再次点击复制,任务开始执行
7. 点击下方任务id,查看复制任务信息,查看成功失败信息,失败的可以查看失败日志

初始化k8s

#没有配置好,想办法下载一个指定版本的git代码包
git clone --branch v1.29.0 --depth 1 https://github.com/kubernetes/kubernetes.git kubernetesv1.29.0

#安装ansible
pip install ansible-core==2.17 -i https://pypi.tuna.tsinghua.edu.cn/simple/

#安装开发包
yum install python3-pip python3-devel -y

#设置全局python版本
pyenv global 3.12.0

#安装k8s集群
ansible-playbook -i inventory/mycluster/inventory.ini --become cluster.yml

安装集群报错
