Use Nodes or Clusters to isolate Workloads with high protection requirements.
Run the following command and review the pods and how they are deployed on Nodes. $ oc get pod -o=custom-columns=NAME:.metadata.name,NAMESPACE:.metadata.namespace,APP:.metadata.labels.app\.kubernetes\.io/name,NODE:.spec.nodeName --all-namespaces | grep -v "openshift-"
You can use labels or other data as custom field which helps you to identify parts of an application.
Ensure that Applications with high protection requirements are not colocated on Nodes or in Clusters with workloads of lower protection requirements.
