Known Issues

  • BET-1491: Portworx currently does not support Kubernetes version 1.19. This results in a failure to bring up the Stork scheduler pod.
  • BET-1472: In the Enterprise Mode, deleting a node in an Enterprise cluster renders the cluster unusable due to an in-tree limitation.
    • Recommendations:
      • To prevent VMDK deletion with the in-tree provider, drain the node, let all pods re-schedule on another node, let all volumes detach from the node, and then finally, delete the node VM.
      • This issue is resolved with vSphere 67u3 and a new CSI driver.
      • A related issue might occur where a persistent volume might not attach to a new node.
  • BET-1461: For AWS clusters, when the Static VPC option is used, clusters might not complete provisioning. This bug will be patched in subsequent releases.
  • BET-768: On the Azure cloud, the choice of Availability Zones (AZ) may be ignored if the selected AZs do not support the requested VM size. Non-Zoned VMs are created in such cases without a warning to the user.
Spectro Cloud adopts relevant security best practices for operating systems, Kubernetes components, and cloud environments. All Spectro Cloud container images are scanned for CVEs before a release. While Spectro Cloud takes ownership of securing the cluster infrastructure, there may be additional 3rd party integrations installed on the Kubernetes clusters provisioned. Security of such 3rd party integrations, including their container images and associated configurations, is the responsibility of the provider.
