Almalinux安装部署kubesphere容器云平台

一、介绍

AlmaLinux是一个开源的、社区驱动的项目，旨在填补CentOS稳定版本消亡所留下的空白。AlmaLinux是RHEL 8的一个1:1二进制兼容的分支，它是由有丰富经验的CloudLinux OS的创建者（Igor Seletskiy）构建的。 官网：https://almalinux.org/ 下载地址：https://mirrors.aliyun.com/almalinux/

二、安装部署流程

1、安装环境依赖软件

[root@localhost ~]# yum update -y
[root@localhost ~]# yum install -y vim wget net-tools 
[root@localhost ~]# yum makecache
[root@localhost ~]# yum install -y conntrack socat 
[root@localhost ~]# yum install yum-utils device-mapper-persistent-data lvm2 -y

2、安装Docker环境

卸载较旧的 Docker 版本称为 docker 或 docker-engine 
yum remove docker \
                  docker-client \
                  docker-client-latest \
                  docker-common \
                  docker-latest \
                  docker-latest-logrotate \
                  docker-logrotate \
                  docker-engine


添加docker仓库源地址（阿里云）
yum-config-manager \
    --add-repo \
    http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo


安装docker（默认安装最新版本）,并设置开机自启动。
yum install docker-ce docker-ce-cli containerd.io -y
systemctl enable docker --now

3、运行环境说明

1）系统信息
[root@localhost ~]# uname -a
Linux localhost.localdomain 5.14.0-70.30.1.el9_0.aarch64 #1 SMP Wed Nov 2 23:05:24 UTC 2022 aarch64 aarch64 aarch64 GNU/Linux

2）系统架构
ARM

3）环境配置
8核，16G内存，64GB存储

4）虚拟化软件
PD 18 for Mac

4、执行命令安装

[root@localhost ~]# export KKZONE=cn
[root@localhost ~]# curl -sfL https://get-kk.kubesphere.io | VERSION=v2.3.0 sh -
[root@localhost ~]# ./kk create cluster --with-kubernetes v1.22.12 --with-kubesphere v3.3.1

5、查看安装日志、验证安装结果

kubectl logs -n kubesphere-system $(kubectl get pod -n kubesphere-system -l 'app in (ks-install, ks-installer)' -o jsonpath='{.items[0].metadata.name}') -f

6、查看docker、K8S版本信息
