# Announce <img align="right" src="https://storage.googleapis.com/poseidon/typhoon-logo-small.png">
## April 26, 2018
Introducing Typhoon Kubernetes clusters for Fedora Atomic!
Fedora Atomic is a container-optimized operating system designed for large-scale custered operation, immutable infrastructure, and atomic operating system upgrades. [Fedora Atomic](https://getfedora.org/en/atomic/download/) is part of [Project Atomic](http://www.projectatomic.io/docs/introduction/), a Red Hat sponsored project working on rpm-ostree, buildah, skopeo, CRI-O, and the related CentOS/RHEL Atomic.
For newcomers, Typhoon is a free (cost and freedom) Kubernetes distribution providing upstream Kubernetes, declarative configuration via [Terraform](https://www.terraform.io/intro/index.html), and support for AWS, Google Cloud, DigitalOcean, and bare-metal. Typhoon clusters use a [self-hosted](https://github.com/kubernetes-incubator/bootkube) control plane, support [Calico](https://www.projectcalico.org/blog/) and [flannel](https://coreos.com/flannel/docs/latest/) CNI networking, and enable etcd TLS, [RBAC](https://kubernetes.io/docs/admin/authorization/rbac/), and network policy.
Typhoon for Fedora Atomic reflects many of the same principles that created Typhoon for Container Linux. Clusters are declared using plain Terraform configs that can be versioned. In lieu of Ignition, instances are declaratively provisioned with Cloud-Init and kickstart (bare-metal only). TLS assets are generated. Hosts run only a kubelet service, other components are scheduled (i.e. self-hosted). The upstream hyperkube is used directly[^1]. And clusters are kept minimal by offering optional addons for [Ingress](https://typhoon.psdn.io/addons/ingress/), [Prometheus](https://typhoon.psdn.io/addons/prometheus/), and [Grafana](https://typhoon.psdn.io/addons/grafana/). Typhoon compliments and enhances Fedora Atomic as a choice of operating system for Kubernetes.
Meanwhile, Fedora Atomic adds some promising new low-level technologies:
* [ostree](https://github.com/ostreedev/ostree) & [rpm-ostree](https://github.com/projectatomic/rpm-ostree) - a hybrid, layered, image and package system that lets you perform atomic updates and rollbacks, layer on packages, "rebase" your system, or manage a remote tree repo. See Dusty Mabe's great [intro](https://dustymabe.com/2017/09/01/atomic-host-101-lab-part-3-rebase-upgrade-rollback/).
* [system containers](http://www.projectatomic.io/blog/2016/09/intro-to-system-containers/) - OCI container images that embed systemd and runc metadata for starting low-level host services before container runtimes are ready. Typhoon uses system containers under runc for `etcd`, `kubelet`, and `bootkube` on Fedora Atomic (instead of rkt-fly).
* [CRI-O](https://github.com/kubernetes-incubator/cri-o) - CRI-O is a kubernetes-incubator implementation of the Kubernetes Container Runtime Interface. Typhoon uses Docker as the container runtime today, but its a goal to gradually introduce CRI-O as an alternative runtime as it matures.
Typhoon has long [aspired](https://github.com/poseidon/typhoon/blob/2faacc6a50993038c98789dfa96430a757bdf545/docs/faq.md#operating-systems) to add a dissimilar operating system to compliment Container Linux. Operating Typhoon clusters across colocations and multiple clouds was driven by real need and has provided healthy perspective and clear direction. Fedora Atomic is an exciting addition because its similarly driven by need and should be healthy for Typhoon. Fedora Atomic diversifies Typhoon's technology underpinnings, uniting the Container Linux and Fedora Atomic ecosystems to provide a consistent Kubernetes experience across operating systems, clouds, and on-premise.
Get started with the [basics](https://typhoon.psdn.io/architecture/concepts/) or read the OS [comparison](https://typhoon.psdn.io/architecture/operating-systems/). If you're familiar with Terraform, follow the new tutorials for Fedora Atomic on [AWS](https://typhoon.psdn.io/atomic/aws/), [Google Cloud](https://typhoon.psdn.io/atomic/google-cloud/), [DigitalOcean](https://typhoon.psdn.io/atomic/digital-ocean/), and [bare-metal](https://typhoon.psdn.io/atomic/bare-metal/).
*Typhoon is not affiliated with Red Hat or Project Atomic.*
!!! warning
Heed the warnings. Typhoon for Fedora Atomic is still alpha. Container Linux continues to be the recommended flavor for production clusters. Atomic is not meant to detract from efforts on Container Linux or its derivatives.
!!! tip
For bare-metal, you may continue to use your v0.7+ [Matchbox](https://github.com/coreos/matchbox) service and `terraform-provider-matchbox` plugin to provision both Container Linux and Fedora Atomic clusters. No changes needed.
[^1]: Using `etcd`, `kubelet`, and `bootkube` as system containers required metadata files be added in [system-containers](https://github.com/poseidon/system-containers)
