基于k8s部署kubesphere

基于k8s部署kubesphere

PS: 具体详情请查看官网: https://kubesphere.io/zh/docs/quick-start/minimal-kubesphere-on-k8s/

前提必须先部署好动态存储,ceph,nfs都可,nfs请查看https://www.yepblog.cn/?p=297

1、下载部署yaml文件
wget https://github.com/kubesphere/ks-installer/releases/download/v3.2.1/kubesphere-installer.yaml

wget https://github.com/kubesphere/ks-installer/releases/download/v3.2.1/cluster-configuration.yaml

2、部署
kubectl apply -f kubesphere-installer.yaml
kubectl apply -f cluster-configuration.yaml
PS: cluster-configuration.yaml文件可以基于自己环境而修改

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

4、如果部署失败,官方提供了如下卸载脚本

#!/bin/bash
function delete_sure(){
  cat << eof
$(echo -e "\033[1;36mNote:\033[0m")
Delete the KubeSphere cluster, including the module kubesphere-system kubesphere-devops-system kubesphere-monitoring-system kubesphere-logging-system openpitrix-system.
eof

read -p "Please reconfirm that you want to delete the KubeSphere cluster.  (yes/no) " ans
while [[ "x"$ans != "xyes" && "x"$ans != "xno" ]]; do
    read -p "Please reconfirm that you want to delete the KubeSphere cluster.  (yes/no) " ans
done

if [[ "x"$ans == "xno" ]]; then
    exit
fi
}
