鲲鹏arm64架构下安装KubeSphere

鲲鹏arm64架构下安装KubeSphere

官方参考文档: https://kubesphere.io/zh/docs/quick-start/minimal-kubesphere-on-k8s/

在Kubernetes基础上最小化安装 KubeSphere
前提条件

官方参考文档: https://kubesphere.io/zh/docs/installing-on-kubernetes/introduction/prerequisites/

  • 如需在 Kubernetes 上安装 KubeSphere 3.2.1,您的 Kubernetes 版本必须为:1.19.x、1.20.x、1.21.x 或 1.22.x(实验性支持)。

  • 确保您的机器满足最低硬件要求:CPU > 1 核,内存 > 2 GB。

  • 在安装之前,需要配置 Kubernetes 集群中的默认存储类型。

uname -a
显示架构如下:
Linux localhost.localdomain 4.14.0-115.el7a.0.1.aarch64 #1 SMP Sun Nov 25 20:54:21 UTC 2018 aarch64 aarch64 aarch64 GNU/Linuxkubectl version
显示版本如下:
Client Version: version.Info{Major:"1", Minor:"19", GitVersion:"v1.19.3", GitCommit:"1e11e4a2108024935ecfcb2912226cedeafd99df", GitTreeState:"clean", BuildDate:"2020-10-14T12:50:19Z", GoVersion:"go1.15.2", Compiler:"gc", Platform:"linux/arm64"}

显示内存如下:total        used        free      shared  buff/cache   available
Mem:            127          48          43           1          34          57

显示存储默认 StorageClass如下:

部署 KubeSphere

确保您的机器满足安装的前提条件之后,可以按照以下步骤安装 KubeSphere。

1 执行以下命令开始安装:
kubectl apply -f https://github.com/kubesphere/ks-installer/releases/download/v3.2.1/kubesphere-installer.yamlkubectl apply -f https://github.com/kubesphere/ks-installer/releases/download/v3.2.1/cluster-configuration.yaml
2 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报错如下:

原因是8080端口,k8s默认不对外开放

开放8080端口

8080端口访问不了,k8s开放8080端口

https://blog.csdn.net/qq_29274865/article/details/108953259

进入 cd /etc/kubernetes/manifests/vim kube-apiserver.yaml
添加
- --insecure-port=8080- --insecure-bind-address=0.0.0.0重启apiserver
docker restart apiserver容器id

在这里插入图片描述

重新执行上面的命令

kubectl delete -f https://github.com/kubesphere/ks-installer/releases/download/v3.2.1/cluster-configuration.yaml
kubectl delete -f https://github.com/kubesphere/ks-installer/releases/download/v3.2.1/kubesphere-installer.yamlkubectl apply -f https://github.com/kubesphere/ks-installer/releases/download/v3.2.1/cluster-configuration.yaml
kubectl apply -f https://github.com/kubesphere/ks-installer/releases/download/v3.2.1/kubesphere-installer.yaml
3 使用 kubectl get pod --all-namespaces 查看所有 Pod 是否在 KubeSphere 的相关命名空间中正常运行。如果是,请通过以下命令检查控制台的端口(默认为 30880):
kubectl get pod --all-namespaces
显示Error
kubesphere-system              ks-installer-d8b656fb4-gb2qg                         0/1     Error               0          27s查看日志
kubectl logs -n kubesphere-system $(kubectl get pod -n kubesphere-system -l app=ks-install -o jsonpath='{.items[0].metadata.name}') -f查看日志报错如下:
standard_init_linux.go:228: exec user process caused: exec format error

原因是arm64架构报错,运行不起来

https://hub.docker.com/
hub官方搜索下镜像有没有arm64的

在这里插入图片描述

根本就没有arm64架构的镜像,找了一圈,发现有个:kubespheredev/ks-installer:v3.0.0-arm64 试试

kubectl delete -f https://github.com/kubesphere/ks-installer/releases/download/v3.2.1/cluster-configuration.yaml
kubectl delete -f https://github.com/kubesphere/ks-installer/releases/download/v3.2.1/kubesphere-installer.yamlkubectl apply -f https://github.com/kubesphere/ks-installer/releases/download/v3.2.1/cluster-configuration.yaml
kubectl apply -f https://github.com/kubesphere/ks-installer/releases/download/v3.2.1/kubesphere-installer.yaml下载镜像
docker pull kubespheredev/ks-installer:v3.0.0-arm64在使用rancher去修改deployments文件,或下载yaml文件去修改
由于我的k8s master节点是arm64架构的,kubesphere/ks-installer 官方没有arm64的镜像
kubesphere/ks-installer:v3.2.1修改为 kubespheredev/ks-installer:v3.0.0-arm64
节点选择指定master节点部署报错如下:
TASK [common : Kubesphere | Creating common component manifests] ***************
failed: [localhost] (item={'path': 'etcd', 'file': 'etcd.yaml'}) => {"ansible_loop_var": "item", "changed": false, "item": {"file": "etcd.yaml", "path": "etcd"}, "msg": "AnsibleUndefinedVariable: 'dict object' has no attribute 'etcdVolumeSize'"}
failed: [localhost] (item={'name': 'mysql', 'file': 'mysql.yaml'}) => {"ansible_loop_var": "item", "changed": false, "item": {"file": "mysql.yaml", "name": "mysql"}, "msg": "AnsibleUndefinedVariable: 'dict object' has no attribute 'mysqlVolumeSize'"}

原因是版本对不上,使用v3.2.1版本,镜像确是v3.0.0-arm64

下面使用v3.0.0版本试试
使用v3.0.0版本
kubectl apply -f https://github.com/kubesphere/ks-installer/releases/download/v3.0.0/kubesphere-installer.yamlkubectl apply -f https://github.com/kubesphere/ks-installer/releases/download/v3.0.0/cluster-configuration.yaml
在使用rancher去修改deployments文件或者下载v3.0.0的yaml文件,并修改
kubesphere-installer.yaml
cluster-configuration.yamlkubesphere-installer.yaml文件修改如下
由于我的k8s master节点是arm64架构的,kubesphere/ks-installer 官方没有arm64的镜像
kubesphere/ks-installer:v3.0.0修改为 kubespheredev/ks-installer:v3.0.0-arm64
节点选择指定master节点部署cluster-configuration.yaml文件修改
endpointIps: 192.168.xxx.xx 修改为k8s master节点IP

不报错,ks-installer也跑起来了,但是其他的没有arm64镜像,其他deployments都跑不起来 ks-controller-manager报错

把所有deployments镜像都换成arm64架构的,节点选择k8s master节点

kubectl logs -n kubesphere-system $(kubectl get pod -n kubesphere-system -l app=ks-install -o jsonpath='{.items[0].metadata.name}') -fkubectl get pod --all-namespacesdocker pull kubespheredev/ks-installer:v3.0.0-arm64
docker pull bobsense/redis-arm64 要去掉挂载的存储pvc,不然报错
docker pull kubespheredev/ks-controller-manager:v3.2.1
docker pull kubespheredev/ks-console:v3.0.0-arm64
docker pull kubespheredev/ks-apiserver:v3.2.0除了ks-controller-manager,其他都运行起来了kubectl get svc/ks-console -n kubesphere-system
显示如下:
NAME         TYPE       CLUSTER-IP   EXTERNAL-IP   PORT(S)        AGE
ks-console   NodePort   10.1.4.225   <none>        80:30880/TCP   6h12m再次查看日志
kubectl logs -n kubesphere-system $(kubectl get pod -n kubesphere-system -l app=ks-install -o jsonpath='{.items[0].metadata.name}') -f
最后显示如下:以为成功了

kubectl logs  ks-controller-manager-646b8fff9f-pd7w7 --namespace=kubesphere-system
ks-controller-manager报错如下:

登录报错: 可能是ks-controller-manager没成功运行
日志如下:
request to http://ks-apiserver.kubesphere-system.svc/oauth/token failed, reason: connect ECONNREFUSED 10.1.146.137:80

应该是openldap没启动成功的原因

查看StatefulSets的openldap日志

提示有2个StorageClasses,删除一个之后就运行成功了
persistentvolumeclaims "openldap-pvc-openldap-0" is forbidden: Internal error occurred: 2 default StorageClasses were found

在这里插入图片描述

删除StorageClasses
查看
kubectl get sc
显示如下:之前有2条记录,是因为我删除了一条
NAME                    PROVISIONER                                   RECLAIMPOLICY   VOLUMEBINDINGMODE   ALLOWVOLUMEEXPANSION   AGE

kubectl delete sc glusterfs

删除StorageClasses 后,只有一个StorageClasses 了, openldap正常运行了,ks-controller-manager也正常运行了,有希望了
