The ability to generate Kubernetes YAML from Podman is under development. Podman can now capture the description of local pods and containers and then help users transition to a more sophisticated orchestration environment like Kubernetes. This article provides a demo to illustrate the process.

The pod concept for containers was introduced in Kubernetes. Podman lets you manage pods locally, giving it an advantage over other container runtimes.

This article focuses on the Open vSwitch (OVS) userspace datapath accelerated with the Data Plane Development Kit (DPDK) and its new feature, partial flow hardware offloading, which can potentially save resources while improving the packet processing rate.

This article discusses two game-changing performance improvements that have been added to Open Virtual Network (OVN), a component of Open vSwitch project, in the past year: ovn-nbctl daemonization and port groups. The article also discusses possible future improvements.
