Kind 是一个使用 Docker 容器“节点”运行本地 Kubernetes 集群的工具。Kind 主要用于测试kubernetes本身但也可用于本地开发或 CI。
2.Kind安装kubernetes集群
2.1.确保已经安装了go环境
# 创建gopath目录
$ mkdir /root/go
$ cd /root/go# 获取go安装包
$ wget https://go.dev/dl/go1.22.1.linux-amd64.tar.gz# 解压并加入/usr/local目录
$ tar -C /usr/local -zxf go1.22.1.linux-amd64.tar.gz# 导出go环境变量
$ vim /# 在文件最后加上下面这些export GOROOT/usr/local/goexport GOPATH/root/goexport GOPROXYhttps://goproxy.cn,directexport PATH$PATH:$GOROOT/bin:$GOPATH/bin# 刷新环境变量
$ source /etc/profile# 查看go版本检查是否安装成功
$ go version2.2.确保已经安装了docker
没有安装docker的执行命令安装# 卸载旧版本docker
$ sudo yum remove docker \docker-client \docker-client-latest \docker-common \docker-latest \docker-latest-logrotate \docker-logrotate \docker-selinux \docker-engine-selinux \docker-engine# 安装依赖包
$ sudo yum install -y yum-utils# 添加 yum 软件源
$ sudo yum-config-manager \--add-repo \https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
$ sudo sed -i s/download.docker.com/mirrors.aliyun.com\/docker-ce/g /etc/yum.repos.d/docker-ce.repo# 更新 yum 软件源缓存并安装 docker-ce
$ sudo yum install docker-ce docker-ce-cli containerd.io# 使用脚本自动安装
$ curl -fsSL get.docker.com -o get-docker.sh
$ sudo sh get-docker.sh --mirror Aliyun# 启动docker
$ sudo systemctl enable docker
$ sudo systemctl start docker# 如果非root用户用下面的命令加入docker组
$ sudo groupadd docker
$ sudo usermod -aG docker $USER# 测试 Docker 是否安装正确有下面的输出则安装成功
$ docker run --rm hello-worldUnable to find image hello-world:latest locally
latest: Pulling from library/hello-world

Status: Downloaded newer image for hello-world:latestHello from Docker!
This message shows that your installation appears to be working correctly.To generate this message, Docker took the following steps:1. The Docker client contacted the Docker daemon.2. The Docker daemon pulled the hello-world image from the Docker Hub.(amd64)3. The Docker daemon created a new container from that image which runs theexecutable that produces the output you are currently reading.4. The Docker daemon streamed that output to the Docker client, which sent itto your terminal.To try something more ambitious, you can run an Ubuntu container with:$ docker run -it ubuntu bashShare images, automate workflows, and more with a free Docker ID:https://hub.docker.com/For more examples and ideas, visit:https://docs.docker.com/get-started/2.3.安装kind
2.3.1.安装命令
sh
# 安装kind工具会安装到 $GOPATH/bin 目录下
$ go install sigs.k8s.io/kindv0.20.0# 验证kind是否安装成功
$ kind version# 安装集群有下面的输出说明安装成功
$ kind create cluster
Creating cluster kind ...✓ Ensuring node image (kindest/node:v1.27.3) ✓ Preparing nodes ✓ Writing configuration ✓ Starting control-plane ️✓ Installing CNI ✓ Installing StorageClass
Set kubectl context to kind-kind
You can now use your cluster with:kubectl cluster-info --context kind-kindHave a nice day! 2.3.2.安装过程遇到cgroup报错
报错信息$ kind create cluster

docker: Error response from daemon: failed to create task for container: failed to create shim task: OCI runtime create failed: runc create failed: cgroup namespaces arent enabled in the kernel: unknown.原因内核版本太低不支持cgroup解决方法对内核升级#1 更新系统确保所有安装的包都是最新的
$ sudo yum update#2安装 elrepo 仓库该仓库提供了最新的稳定内核
$ sudo rpm --import https://www.elrepo.org/RPM-GPG-KEY-elrepo.org
$ sudo yum install -y https://www.elrepo.org/elrepo-release-7.el7.elrepo.noarch.rpm#3 安装新的内核例如最新的稳定版本是 kernel-ml
$ sudo yum --enablerepoelrepo-kernel install kernel-ml -y#4 更新GRUB引导菜单
$ sudo grub2-mkconfig -o /boot/grub2/grub.cfg#5 修改默认引导顺序使新内核成为默认引导
$ sudo grub2-set-default 0#6 重新启动系统确认新内核成功安装并生效
$ sudo reboot2.3.3.安装过程遇到 failed to init node with kubeadm 错误
错误信息$ kind create cluster

Command Output: cannot exec in a stopped state: unknown原因kind版本太高或太低 我让大家安装的是 kind 1.20.0按照步骤来不会有问题 解决方法更换kind版本多试几个版本# 重新下载合适的kind版本更改后面的版本号
$ go install sigs.k8s.io/kindv0.20.0# 重新安装
$ kind create cluster
