Kind 简介
kind是一个使用 Docker 容器“节点”运行本地 Kubernetes 集群的工具。
kind 主要是为测试 Kubernetes 本身而设计的，但也可以用于本地开发
- kind 支持多节点（包括 HA）集群
- kind 支持从源代码构建 Kubernetes 发布版本
- 支持 make / bash 或 docker
- kind 支持 Linux、macOS 和 Windows
- kind 是经过 认证的 Kubernetes 安装程序
Kind安装
curl -Lo ./kind https://kind.sigs.k8s.io/dl/v0.12.0/kind-linux-amd64
chmod +x ./kind
mv ./kind /some-dir-in-your-PATH/kind
运行脚本： curl -Lo ./kind https://kind.sigs.k8s.io/dl/v0.12.0/kind-linux-amd64
[root@localhost my_setup_libs]# ls
[root@localhost my_setup_libs]# curl -Lo ./kind https://kind.sigs.k8s.io/dl/v0.12.0/kind-linux-amd64

[root@localhost ~]# kind
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.
创建集群，默认情况下，集群将被命名为 name kind。使用该–name标志为集群分配不同的上下文名称。如果您希望create cluster命令阻塞直到控制平面达到就绪状态，您可以使用–wait标志并指定超时。要使用–wait您必须指定等待时间的单位。例如，等待 30 秒，做–wait 30s，等待 5 分钟–wait 5m，等等。
