Prerequisites checklist for air-gapped Bring-Your-Own (BYO) cluster installation

Before installing ITRS Analytics, ensure that all the prerequisites are met in the environment where you will deploy.

• Make sure that your Kubernetes version is compatible with the ITRS Analytics Platform. Please refer to the Cluster Types and Kubernetes section for more information.

• Check that resource and hardware requirements are met.

• Provide access to a Docker registry to pull and push container images. The host name must support Docker v2 protocol.

• Note the host name of the server, which will be used for accessing ITRS Analytics from outside the Kubernetes cluster.

• Make sure that you have host names for accessing ITRS Analytics from outside the Kubernetes cluster. These host names must be mapped to the corresponding Kubernetes services that will be created during installation.

  • Web UI: for example obcerv.mydomain.internal.
  • Data ingestion: to publish from Geneos Gateways; for example ingestion-obcerv.mydomain.internal.

• Make sure that a load balancer is configured for your cluster.

• Check that cluster permissions are set. Cluster role configs are required on a BYO cluster. You can also opt to grant minimal RBAC permissions to KOTS.

• Before installing, you can deploy and scan ITRS Docker images. Refer to this sample list of images from the Docker registry

• Make sure that you are not using ARM64 processors, which is currently not supported in airgap installations.
