阿里云自建k8s存储插件csi安装使用

新钛云服已为您服务1213天

前言

k8s在阿里云上使用，推荐还是使用阿里云的ack。无论是从稳定性，以及后期的维护来说，ack 都是最优的方案，自建k8s 阿里云不提供任何帮助，一旦集群出现问题（主要是网络问题）很难进行排查。

如果出于特殊原因，希望在阿里云上进行自建k8s当然也可以。自建k8s需要集成阿里云两个重要的插件cloud-controller-manager（负载均衡插件），csi(存储插件)。两个插件在k8s 1.20 测试可用。下面我们将进行csi 存储插安装。

CSI 插件部署

部署rbac.yml

kubectl apply -f rbac.yaml

查看生成的 secrets 的csi token 名字

[root@sh-dev-test-staging-k8s-master-01 ack]# kubectl get secrets -A |grep csi
kube-system csi-admin-token-ssflh kubernetes.io/service-account-token 3 2d14h

修改csi-plugin-managed.yaml & csi-provisioner-managed.yaml

两个文件修改位置一致请参考下图

kubectl apply -f csi-plugin-managed.yaml
kubectl apply -f csi-provisioner-managed.yaml

nodes 打 providerID

providerID 对应的值为以下两行的输出
META_EP=http://100.100.100.200/latest/meta-data
echo `curl -s $META_EP/region-id`.`curl -s $META_EP/instance-id`
