ubuntu20.0.4 安装kubesphere

Kubernetes 集群管理平台有openshift，rancher, kubesphere

值得一提kubesphere是国人开发的。今天以all in one的方式同时安装kubernetes和kubesphere

1. 参考文档

All-in-One Installation on Linux (kubesphere.io)

2. 裸机

操作系统ubuntu20.0.4， cpu 16核， 内存16g，硬盘300G

3. 首先安装各种依赖

sudo apt update

sudo apt install openssh-server openssh-client

sudo apt install curl socat conntrack ebtables ipset

4. 安装docker

Install Docker Engine on Ubuntu | Docker Documentation

sudo apt-get update

sudo apt-get install \    apt-transport-https \    ca-certificates \    curl \    gnupg \    lsb-release

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg

echo \  "deb [arch=amd64 signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/ubuntu \  $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

sudo apt-get update

sudo apt-get install docker-ce docker-ce-cli containerd.io

5. 国内安装

首先设置参数

export KKZONE=cn

然后执行

curl -sfL https://get-kk.kubesphere.io | VERSION=v1.0.1 sh -

6. 一些下载困难的软件

执行下面命令，如果出现无法下载

sudo ./kk create cluster --with-kubernetes v1.18.6 --with-kubesphere v3.0.0

如果无法下载helm，就从华为镜像手动下载

https://mirrors.huaweicloud.com/helm/v3.2.1/

然后把helm放到目录

/home/xxx/kubekey/v1.18.6/amd64

如果cni插件从github下载困难，则手动用fastgit加速

https://hub.fastgit.org/containernetworking/plugins/releases/tag/v0.8.6

不用解压，直接放到目录

/home/xxx/kubekey/v1.18.6/amd64

7. 继续执行

sudo ./kk create cluster --with-kubernetes v1.18.6 --with-kubesphere v3.0.0

执行完毕，如果出现无法访问8080端口，就继续执行一遍

8.安装成功

kubesphere config is under $home/kubekey

export KUBECONFIG=~/kubekey/config

把export命令加入到.bashrc文件中，然后source一下

10. 访问kubesphere

浏览器输入
