Requirements

  • The K8s administrator is responsible for performing backups according to organizational requirements.
  • K8s service account to deploy IEM extensions to the K8s cluster.
  • Kubernetes cluster 1.23 or higher is required.
  • If the target namespace does not exist, it will be created. The provisioning CLI stores its configuration data in the target namespace. If the namespace is not set with the -n flag, it defaults to iem.
  • Whitelist domains of Industrial Edge cloud services for outbound traffic, see the Industrial Edge - Security overview.
  • The IEM services must be able to invoke themselves via a public cluster entry point configured with the provision cli flag --set global.hostname=. This limitation will be fixed in future releases.
  • Kubernetes cluster requires connection to IEHub to be able to download:
    • Container Images
    • IED Apps
    • Firmware
    • Device Types
  • Ensure that you whitelist these domains.

NOTICE

The IP of the IEM must not be changed or the IEDs will not communicate with the IEM.

Infrastructure requirements

  • Free worker nodes with at least 8 GB RAM and 4 (v)CPUs, if you want to enable additional extensions like firmware management, it's recommended to have at least 16 GB RAM for robust operation.
  • The installation will request multiple persistent volume requests, the operator must either install and use a dynamic storage provisioner or fulfill the pvc requests manually.
  • The minimal requirements vary depending on the configuration chosen.
