在 Linux 上以 All-in-One 模式安装 KubeSphere
夏侯阳
前言
最近部门内需要进行私有化部署，所以这个系列主要是以docker+Kubernetes 技术选型和的调研为主了。
很久没有更新博客，这里把自己的随笔记录到博客中，后续再进行详细整理吧
一、在 Linux 上以 All-in-One 模式安装 KubeSphere
为什么不纯手动安全k8s呢？
首先我们是想选购一个成型的标准封装尽量简化我们的安装流程。
其次我们如果实现这个标品是ok的那么，其实就获得了它的离线安装能力。
当然也有一些缺点，我们不清楚内部构造，重启服务遇到问题时，我们也无法进行问题解决，所以我感觉先试用这个服务后续还要进行一把纯手动安装这样要清楚的知道哪部分出了啥问题。
安装步骤
前置准备
我是用mac电脑安装的vmware进行的操作，因为它只能支持linux下的操作环境。然后你需要下载centos7的镜像，然后把你的虚拟机安装才行。
实际安装
参照网址安装：
https://kubesphere.com.cn/docs/quick-start/all-in-one-on-linux/
安装步骤如下：
#需要先下个叫kk的小东西
export KKZONE=cn
curl -sfL https://get-kk.kubesphere.io | VERSION=v2.0.0 sh -
#开始安装，设置版本号
./kk create cluster --with-kubernetes v1.21.5 --with-kubesphere v3.2.1
#然后大体操作流程就是它会从各种数据源中获取到镜像文件
downloading amd64 kubelet v1.21.5 ...
21:56:43 PDT message: [localhost]
#执行安装这些镜像和install的镜像
21:59:53 PDT [InstallETCDBinaryModule] Install etcd using binary
21:59:54 PDT success: [localhost.localdomain.cluster.local]
#最后会卡到这里，最后那个点就是菊花了，一直等它转完就ok了
#这里的速度取决于机器配置了，2CPU 4G内存，至少半小时。
clusterconfiguration.installer.kubesphere.io/ks-installer created
22:00:43 PDT success: [localhost.localdomain.cluster.local]
Please wait for the installation to complete: >>--->
#安装完毕是这个界面：

Installation is complete.
Please check the result using the command:
kubectl logs -n kubesphere-system $(kubectl get pod -n kubesphere-system -l app=ks-install -o jsonpath='{.items[0].metadata.name}') -f
记录一下当前机器的images和ps容器，方便后续排查问题。真是感觉后续可能有问题不好排查，因为k8s的文档才是最全的。

思考:我们安装k8s需要解决哪些问题？
以优先级高地排名吧
- 服务高可用问题
- 服务纯离线部署问题
- 服务devops问题
- 服务监控问题
