I just installed a DC/OS Cluster on Azure using Terraform. Now I was wondering if it's possible to automatically mount Data Disks of agent nodes under /dcos/volume<N>. As far as I understood the docs, this is a manual task. Wouldn't it be possible to automate this step with Terraform? I was looking through the DC/OS docs and Terraform docs but I couldn't find anything related to auto mounting.
It seems you just can mount the Data disks to the node of AKS manual as a volume. It's a Kubernetes task, not Azure's. Azure only can manage the data disk for you.
What you can do through the Terraform is attach the data disk to the node itself of AKS as a disk, not a volume of the AKS. And the volume, you only can create it through Kubernetes, not Azure. So Terraform also cannot help you achieve it automated.
