OKD

What OKD is

OKD is a free, self-hosted Kubernetes platform for managing applications and clusters at scale. It adds more than 100 preinstalled Operators for cluster components, with a web console, authentication, image registry and tooling, monitoring, networking, node configuration and upgrades, and Operator management. Cluster nodes run an immutable operating system managed and updated through cluster APIs. OKD says it is 100% compliant with Kubernetes, with additional patches for some advanced features; it also supports autoscaling, rolling updates, and policy controls. Deployments can run on bare metal, virtualization platforms, or cloud platforms, with either installer-provisioned or user-provisioned infrastructure. Integrated deployments cover projects in GitOps, service mesh, virtualization, and storage. The platform's defaults include hardened configuration. Installation requires infrastructure with sufficient resources, so the installation guide says Code-Ready Containers may suit a typical developer workstation better when compute and memory are limited. The guide points to stable releases and nightly builds and explains how to verify downloads with signed checksums and the maintainers' public key.
