kind介绍

k8s 单机安装的方式有很多，如：

• 通过docker desktop桌面一键部署
• 通过minikube部署一个单节点的k8s集群
• 通过kubeadm部署并定理k8s集群工具
• 通过kind部署一个k8s集群，支持多节点, 需要docker

Kind 是 Kubernetes In Docker 的缩写，顾名思义是使用 Docker 容器作为 Node 并将 Kubernetes 部署至其中的一个工具。其实内部也是kubeadm来管理集群的。

kind安装 二进制方式安装

这里选择二进制方式安装，so fast and so easy ~

# for Intel Macs [ $(uname -m) = x86_64 ]&& curl -Lo ./kind kind.sigs.k8s.io/dl/v0.13.0/kind-darwin-amd64 # for M1 / ARM Macs [ $(uname -m) = arm64 ] && curl -Lo ./kind kind.sigs.k8s.io/dl/v0.13.0/kind-darwin-arm64 chmod +x ./kind mv ./kind /some-dir-in-your-PATH/kind # 我的执行 mv ./kind ~/devTools/k8s/kind # 为kind配置环境变量 vim ~/.zprofile export PATH=${PATH}:~/devTools/k8s $ kind version kind v0.13.0 go1.18 darwin/arm64 kind命令

先查看一下kind命令，支持哪些操作

$ ./kind --help kind creates and manages local Kubernetes clusters using Docker container 'nodes' Usage: kind [command] Available Commands: build Build one of [node-image] completion Output shell completion code for the specified shell (bash, zsh or fish) create Creates one of [cluster] delete Deletes one of [cluster] export Exports one of [kubeconfig, logs] get Gets one of [clusters, nodes, kubeconfig] help Help about any command load Loads images into nodes version Prints the kind CLI version Flags: -h, --help help for kind --loglevel string DEPRECATED: see -v instead -q, --quiet silence all stderr output -v, --verbosity int32 info log verbosity, higher value produces more output --version version for kind Use "kind [command] --help" for more information about a command.

kind create cluster 命令

$ ./kind create cluster --help Creates a local Kubernetes cluster using Docker container 'nodes' Usage: kind create cluster [flags] Flags: --config string path to a kind config file -h, --help help for cluster --image string node docker image to use for booting the cluster --kubeconfig string sets kubeconfig path instead of $KUBECONFIG or $HOME/.kube/config --name string cluster name, overrides KIND_CLUSTER_NAME, config (default kind) --retain retain nodes for debugging when cluster creation fails --wait duration wait for control plane node to be ready (default 0s) Global Flags: --loglevel string DEPRECATED: see -v instead -q, --quiet silence all stderr output -v, --verbosity int32 info log verbosity, higher value produces more output 创建默认单节点集群

# 创建一个默认集群并指定集群名称，名称需要满足规则： `^[a-z0-9.-]+$` $ ./kind create cluster --name my-test-cluster Creating cluster "my-test-cluster" ... ✓ Ensuring node image (kindest/node:v1.24.0)
