External provisioner "alicloud/disk fails to create volume
I was not able to solve the issue but the problems I had was related to Aliyun Managed Serverless K8s. Even Aliyun Support admitted that such configuration is difficult. They have not provided any solution. We decided to go with Managed K8s (non-serveless). We use Terraform scripts. Everything worksout of the box including Ingress, LogTrail, PvC which were a real pain with serverless managed k8s.
The point is - dont waste your time with Managed Serveless K8s if you need logs and pvc. It doesnt work - at least hasn't worked for us and not much help from Aliyun support for that matter.
If you are using alicloud ASK, this file https://github.com/AliyunContainerService/serverless-k8s-examples/blob/master/volumes/alicloud-disk-controller.yaml is working for me.
