--在 Kubernetes 上最小化安装 KubeSphere

--https://kubesphere.io/zh/docs/v3.3/quick-start/minimal-kubesphere-on-k8s/

kubesphere v3.3.2 install

https://github.com/kubesphere/ks-installer/releases/download/v3.3.2/kubesphere-installer.yaml

https://github.com/kubesphere/ks-installer/releases/download/v3.3.2/cluster-configuration.yaml

kubectl apply -f kubesphere-installer.yaml

kubectl apply -f cluster-configuration.yaml

检查安装日志：

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

[root@master ~]# kubectl get svc/ks-console -n kubesphere-system

NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE

ks-console NodePort 10.111.186.1 80:30880/TCP 23m

验证：

http://you ip address:30880/

使用默认帐户和密码 (admin/P@88w0rd) 访问 Web 控制台。

--报错

request to http://ks-apiserver/oauth/token failed, reason: getaddrinfo EAI_AGAIN ks-apiserver

问题解决方法：https://github.com/kubesphere/website/issues/1896

kubectl -n kube-system edit cm coredns -o yaml

解决：注释掉 forward，关闭转发

--查看日志

kubectl logs ks-console-f4549b894-fhs4z -n kubesphere-system |less

通常情况下，vm.dirty_ratio的值要大于vm.dirty_background_ratio的值。

# sysctl -w vm.dirty_background_ratio=5

# sysctl -w vm.dirty_ratio=10

# sysctl -a | grep "dirty"

--启用应用商店

使用 admin 用户登录控制台，点击左上角的平台管理，选择集群管理。

点击定制资源定义，在搜索栏中输入 clusterconfiguration，点击结果查看其详细页面。

在该 YAML 文件中，搜索 openpitrix，将 enabled 的 false 改为 true。完成后，点击右下角的确定，保存配置。

在 kubectl 中执行以下命令检查安装过程：

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

验证：

http://you ip address:30880/apps

--在 Linux 上以 All-in-One 模式安装 KubeSphere 3.3.2 kubernetes 1.25.5

-- down kk

curl -sfL https://get-kk.kubesphere.io | VERSION=v3.0.7 sh -

chmod +x kk

--可以运行 ./kk version --show-supported-k8s，查看能使用 KubeKey 安装的所有受支持的 Kubernetes 版本。

--若要同时安装 Kubernetes 和 KubeSphere，可参考以下示例命令：

# ./kk create cluster --with-kubernetes v1.25.5 --with-kubesphere v3.3.2

# ./kk create cluster --with-kubernetes v1.25.5 --with-kubesphere v3.3.2 --container-manager containerd

[root@master ~]# ./kk create cluster --with-kubernetes v1.25.5 --with-kubesphere v3.3.2 --container-manager containerd
