  • Coming to Grips with Linux Pressure Stall Information

    The Linux Pressure Stall Information, as part of the Control Group v2, provides an accurate accounting of a containers cpu, memory and io. The psi stats allow accurate and limited access to resources – no over-committing and no over-sizing. However, it sometimes is difficult to see if the a container is being limited and could use more resources…

  • Setting up nfs-provisioner on OpenShift on Power Systems with a template

    Here are my notes for setting up the SIG’s nfs-provisioner. You should follow these directions to setup the nfs-provisioner kubernetes-sigs/nfs-subdir-external-provisioner. a. Create the namespace b. Annotate the namespace with elevated privileges so we can create NFS mounts ❯ oc get sc NAME         PROVISIONER                                   RECLAIMPOLICY   VOLUMEBINDINGMODE   ALLOWVOLUMEEXPANSION   AGE nfs-client   k8s-sigs.io/nfs-subdir-external-provisioner   Delete          Immediate           false                  3m27s If you…

  • April 2024 Updates

    Here are some updates for April 2024. FYI: I was made aware of kubernetes-sigs/kube-scheduler-simulator and the release simulator/v0.2.0. That’s why we are developing a simulator for kube-scheduler — you can try out the behavior of the scheduler while checking which plugin made what decision for which Node. https://github.com/kubernetes-sigs/kube-scheduler-simulator/tree/simulator/v0.2.0 Added a new fix for imagestream set…
