HackMDIntroducing CentOS Stream CoreOS and OKD Streams
CentOS Stream CoreOS (SCOS) is a Linux distribution built from CentOS Stream RPM packages, and focused on running container-based workloads with Kubernetes. It is part of the SCOS Stream of OKD, the Kubernetes community distribution of OpenShift, co-maintained by the CentOS Cloud SIG and the OKD Working Group.
In this presentation, we'll present the technologies and methodologies driving the CentOS Stream CoreOS (SCOS) release engineering, and the Cloud-Native architecture we leverage to package the operating system that runs Kubernetes/OKD.
We'll show how this framework, powered by Tekton pipelines and operated via GitOps, can enable, thanks to rpm-ostree, the CoreOS Assembler and the Layering model, delivery scenarios for different OSes beyond the Cloud-Native ones: IoT, multimedia, automotive, thin-client-based environments. Users can derive their own purpose-driven variants by maintaining a common multi-arch base OS, distributed as a bootable Open Container Image (OCI).
