环境:
kubesphere:3.1.1
kubernetes:1.20.4
系统:ubuntu 20.04
1、准备4台机器,1台做master节点,3个worker节点
配置如下:
master节点:4核 16G
worker节点:8核 32G
下面进入安装步骤:
1、在所有机器上安装docker,提前配置好阿里的apt源(ubuntu20.04配置国内apt源_johnhuster的专栏-CSDN博客)
2、执行命令apt install docker.io安装docker
3、配置docker国内加速(很有必要),修改/etc/docker/daemon.json文件
4、使上述配置生效,执行命令:
systemctl daemon-reload
systemctl restart docker
5、下载kubekey文件,执行命令
curl -sfL https://get-kk.kubesphere.io | VERSION=v1.1.1 sh -
6、创建config文件,执行命令
./kk create config
7、修改生成的config-sample文件,
spec:
hosts:
- - {name: master, address: xx.xx.xx.1, internalAddress: xx.xx.xx.1, user: xx, password: xxxx}
- {name: worker1, address: xx.xx.xx.2, internalAddress: xx.xx.xx.2, user: xx, password: xxxx}
- {name: worker2, address: xx.xx.xx.2, internalAddress: xx.xx.xx.3, user: xx, password: xxxx}
- {name: worker3, address: xx.xx.xx.4, internalAddress: xx.xx.xx.4, user: xx, password: xxxx}
roleGroups:
etcd:
- master
master:
- master
worker:
- worker1
- worker2
- worker3
8、创建kubesphere集群,执行命令
./kk create cluster -f config-sample.yaml
9、 集群创建成功后会打印如下信息
