Prerequisites This article is written with Bright Cluster Manager 9.2 in mind, where Kubernetes is currently deployed with the default version 1.24.9 using containerd as its container runtime. The instructions are written with RHEL 8 and Ubuntu 20.04 in mind. These instructions have been run in dev environments a couple…
0. Prerequisites This KB article assumes a Rocky9 cluster and NVIDIA cluster manager version 9.2. This KB article assumes a Kubernetes installation already present (based on Calico or Flannel) The Kubernetes setup wizard does currently not support Cilium. If support is added we will update this KB article accordingly. 1….
