IBM Cloud - Structured Ideas


This portal is to open public enhancement requests against IBM Cloud and its products. To view all of your ideas submitted to IBM, create and manage groups of Ideas, or create an idea explicitly set to be either visible by all (public) or visible only to you and IBM (private), use the IBM Unified Ideas Portal (https://ideas.ibm.com).

automatic IKS worker replacement as a response to a certain metric (classic or VPC infrastructure)

While operating IBM Kubernetes (IKS) clusters (classsic infrastructure) we have run several times into a situation where IKS worker nodes start under-performing. We notice performance issues that are usually visible as:

  • Read timeouts while performing intense read operations via network from other applications running in our IKS cluster.

  • High IOWait metrics at worker pool level that we notice because we capture worker level OS metrics in all our worker nodes.

Such events happen at least once a month in our IKS clusters.

These problems are most of the time worked around by:

  • Cordoning the worker node

  • Draining the worker node

  • Waiting for auto-scaler to trigger a scale out event

  • Allowing IKS to add the new worker node in the relevant worker pool (it takes around 10 minutes to spin up a new VSI)

  • Remove the cordoned node from the IKS cluster


It would be really useful if IKS could handle these sort of events with an auto healing feature. And example of such feature is how Auto-Scaling Groups at AWS react when an instance fails its configured health check. Such feature is described at https://docs.aws.amazon.com/autoscaling/ec2/userguide/ts-as-healthchecks.html#ts-failed-status-checks
