  • Getting Started with a Sock-Shop – a sample multi-arch compute application

    Original post was at https://community.ibm.com/community/user/powerdeveloper/blogs/paul-bastide/2024/04/26/getting-started-with-a-sock-shop-a-sample-multi-ar?CommunityKey=daf9dca2-95e4-4b2c-8722-03cd2275ab63 I’ve developed the following script to help you get started deploying multiarchitecture applications and show elaborate on the techniques for controllin multiarch compute. This script uses the sock-shop application which is available at https://github.com/ocp-power-demos/sock-shop-demo . This series of instructions for sock-shop-demo requires kustomize and following the readme.md in the repository to setup the username…

  • 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…

  • Replay: Getting started with Multi-Arch Compute workloads with your Red Hat OpenShift cluster

    I presented on: The Red Hat OpenShift Container Platform runs on IBM Power systems, offering a secure and reliable foundation for modernizing applications and running containerized workloads. Multi-Arch Compute for OpenShift Container Platform lets you use a pair of compute architectures, such as ppc64le and amd64, within a single cluster. This exciting feature opens new…
