Kubernetes上安装KubeSphere

安装helm

创建helm文件夹，手动下载helm安装包，放入helm文件夹

tar -zxf helm-v3.2.1-linux-amd64.tar.gz && mv linux-amd64/helm . && rm -rf *linux-amd64*
mv helm /usr/local/bin/

查看helm版本

[root@k8s-master01 3.1.1]# helm version
version.BuildInfo{Version:"v3.2.1", GitCommit:"fe51cd1e31e6a202cba7dead9552a6d418ded79a", GitTreeState:"clean", GoVersion:"go1.13.10"}

安装 OpenEBS

查看 master的污点

kubectl describe node k8s-master01 | grep Taint

去除master的污点

kubectl taint nodes k8s-master01 node-role.kubernetes.io/master:NoSchedule-

添加OpenEBS LocalPV仓库到helm

helm repo add openebs-localpv https://openebs.github.io/dynamic-localpv-provisioner

安装OpenEBS

helm install openebs openebs-localpv/localpv-provisioner --namespace openebs --create-namespace

等待openebs相关pod创建完毕

kubectl get pods -n openebs

查看storageclass

[root@k8s-master01 helm]#  kubectl get sc
NAME               PROVISIONER        RECLAIMPOLICY   VOLUMEBINDINGMODE      ALLOWVOLUMEEXPANSION   AGE
openebs-device     openebs.io/local   Delete          WaitForFirstConsumer   false                  109s
openebs-hostpath   openebs.io/local   Delete          WaitForFirstConsumer   false                  109s

设置默认sc

kubectl patch storageclass openebs-hostpath -p '{"metadata": {"annotations":{"storageclass.kubernetes.io/is-default-class":"true"}}}'

安装 KubeSphere

先贴出安装出错后的卸载方法，创建kubesphere-delete.sh文件

sh kubesphere-delete.sh

在k8s集群的master节点上执行，没反应的话就去手动下载对应文件

kubectl apply -f https://github.com/kubesphere/ks-installer/releases/download/v3.1.1/kubesphere-installer.yaml

kubectl apply -f https://github.com/kubesphere/ks-installer/releases/download/v3.1.1/cluster-configuration.yaml

检查安装日志：

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

检查kubesphere所有pod是否成功启动

kubectl get pods --all-namespaces

等待安装完成后，过以下命令检查控制台的端口（默认为 30880）

[root@k8s-master01 kubesphere]# kubectl get svc/ks-console -n kubesphere-system
NAME         TYPE       CLUSTER-IP    EXTERNAL-IP   PORT(S)        AGE
ks-console   NodePort   10.99.39.85   <none>        80:30880/TCP   35m

netstat -lntp

确保在安全组中打开了端口 30880，并通过 NodePort (IP:30880) 使用默认帐户和密码 (admin/P@88w0rd) 访问 Web 控制台

Account: admin
Password: P@88w0rd
