Hi Ingo, k8s was one of the hardest aspects of the proposal. The main rationale for how the draft looks like now is that k8s is, at least for now, technically not a container runtime but an orchestration tool. We do cover Docker, as it is useful on its own, too, so candidates show their proficiency in containerization in its original definition. Regarding k8s, we could aim for several potential approaches: We could cover handling objects in k8s (most of the stuff that goes into a yaml file to be used with kubectl apply), but that would leave the field of virtualization and enter the field of application design. We do cover this in the DevOps Tools Enginner exam and I'm not sure if a Linux Virtualization expert would actually deal with Deployments and PVCs. We could also cover the administration of k8s which, however, could be an exam on its own. Since we're talking about LPIC-3, we would certainly have to discuss specific storage classes, networking plugins or go into details of kube-proxy implementation and kubelet parameters. We would also probably consider kubeadm, although my impression is that the majority of productive clusters either run in the cloud or are deployed using higher level management tools such as Rancher, kops, kubespray, you name it. Squeezing all this into one aspect of several aspects within one exam doesn't seem to work out easily. That's why the proposal tests k8s deep enough to be sure the candidates are aware of it and its major principles, but does not require any in-depth knowledge about either of its these.
So much for the rationale of the draft. How much kubernetes would you like to see in the exam personally? And what does the rest think? We can change the draft in any directions, but we should be sure to consider the relevance of the topics and the effort of learning/training it.
