The Kubernetes API can be extended using Custom Resources, which represent objects that are not part of the standard Kubernetes installation. These custom resources are declared using Custom Resource Definitions (CRDs), which is a kind of resource that can be dynamically registered and unregistered without shutting down or restarting a cluster ...
Container clusters need to be managed. This includes functionality to create a cluster, to upgrade the software or repair it, balance the load between existing instances, scale by starting or stopping instances to adapt to the number of users, to log activities and monitor produced logs or the application itself by querying sensors.
The following tables compare general and technical information for notable computer cluster software. This software can be grossly separated in four categories: Job scheduler, nodes management, nodes installation and integrated stack (all the above).
This level of control enables the cluster to support upgrades and patches of the control plane nodes with minimal effort. The compute nodes can be running Red Hat CoreOS, RHEL or even Windows. OpenShift introduced the concept of routes - points of traffic ingress into the Kubernetes cluster. The Kubernetes ingress concept was modeled after this ...

Cilium began as a networking project and has many features that allow it to provide a consistent connectivity experience from Kubernetes workloads to virtual machines and physical servers running in the cloud, on-premises, or at the edge. Some of these include: Container Network Interface (CNI) [65] - Provides networking for Kubernetes clusters
An open-source container storage interface (CSI) driver enables BeeGFS to be used with container orchestrators like Kubernetes. [11] The driver is designed to support environments where containers running in Kubernetes and jobs running in traditional HPC workload managers need to share access to the same BeeGFS file system.
