Can SentinelOne be installed on ROSA?

Solution Verified - Updated -

Environment

  • Red Hat OpenShift Service on AWS (ROSA)
    • v4.x

Issue

  • SentinelOne website specify it is supported to be installed on OpenShift, but not on ROSA

  • SentinelOne running on infra and master nodes service log:

"summary": "Action required: Remove custom workload from control plane/infra nodes",
"description": "Your cluster requires you to take action because there is a custom workload scheduled on control plane/infra nodes: ip-10-0-171-139.ec2.internal. The control plane and infrastructure nodes are reserved for Red Hat workloads required to operate the service, as described in the Red Hat OpenShift Dedicated Service Definition. Custom workloads can negatively impact the availability/supportability of control plane and infrastructure nodes. Please ensure this workload does not schedule to these nodes. For more information please refer to https://docs.openshift.com/rosa/rosa_architecture/rosa_policy_service_definition/rosa-service-definition.html#rosa-sdpolicy-compute_rosa-service-definition.",

Resolution

  • SentinelOne is determined as custom workload which is supported on ROSA.

  • SentinelOne should not run on managed infra and master nodes based on our ROSA policy
