Likewise a combination of RDT, RAS and other platform metrics can be used to provide a signal for the overall health of a node and be used to proactively ensure workload resiliency.

 A secret called extender-secret will need to be created with the cert and key for the TLS endpoint. TAS will not deploy if there is no secret available with the given deployment file.

 ## Assumptions 
 This guide requires TAS be running as described in the README, and that the [custom metrics pipeline](custom-metrics.md) is supplying it with up to date metrics. Also required is a multinode Kubernetes set-up with user access to all three machines in the cluster.

 If the helm charts were used to install the metrics pipeline this directory will already be created. If another method of setting up Node Exporter was followed the [textfile collector](https://github.com/prometheus/node_exporter#textfile-collector) will need to be enabled in Node Exporter's configuration.

 ### Descheduler
-[Kubernetes Descheduler](https://github.com/kubernetes-sigs/descheduler) allows control of pod evictions in the cluster after being bound to a node. Descheduler, based on its policy, finds pods that can be moved and evicted.  There are many ways to install and run the K8s [Descheduler](https://github.com/kubernetes-sigs/descheduler#quick-start). Here, we have executed it as a [deployment](https://github.com/kubernetes-sigs/descheduler#run-as-a-deployment).
