    Refer to this article for the mandatory and optional storage pool parameters, along with their default values.

    Currently, Azure Container Storage supports only Azure Kubernetes Service (AKS) with storage pools provided by Azure Disks, Ephemeral Disk, or Azure Elastic SAN.

  • Does Azure Container Storage support read-write-many (RWX) workloads?
    Azure Container Storage doesn't support RWX workloads. However, Azure's first-party Files and Blob CSI drivers are great alternatives and fully supported.

  • Is there any performance impact when upgrading to a new version of Azure Container Storage?
    If you leave autoupgrade turned on (recommended), you might experience temporary I/O latency during the upgrade process. If you turn off autoupgrade and install the new version manually, there won't be any impact; however, you won't get the benefit of automatic upgrades and instant access to new features.

  • How do I remove Azure Container Storage?
