[![Mastodon](https://img.shields.io/badge/follow-news-6364ff?logo=mastodon&style=flat-square)](https://fosstodon.org/@typhoon)Typhoon is a minimal and free Kubernetes distribution.
* Minimal, stable base Kubernetes distribution
* Declarative infrastructure and configuration
* [Free](#social-contract) (freedom and cost) and privacy-respecting
* Practical for labs, datacenters, and cloudsTyphoon distributes upstream Kubernetes, architectural conventions, and cluster addons, much like a GNU/Linux distribution provides the Linux kernel and userspace components.
* Kubernetes v1.31.3 (upstream)
* Single or multi-master, [Calico](https://www.projectcalico.org/) or [Cilium](https://github.com/cilium/cilium) or [flannel](https://github.com/coreos/flannel) networking
* On-cluster etcd with TLS, [RBAC](https://kubernetes.io/docs/admin/authorization/rbac/)-enabled, [network policy](https://kubernetes.io/docs/concepts/services-networking/network-policies/), SELinux enforcing
* Advanced features like [worker pools](https://typhoon.psdn.io/advanced/worker-pools/), [preemptible](https://typhoon.psdn.io/flatcar-linux/google-cloud/#preemption) workers, and [snippets](https://typhoon.psdn.io/advanced/customization/#hosts) customization
* Ready for Ingress, Prometheus, Grafana, CSI, or other [addons](https://typhoon.psdn.io/addons/overview/)## Modules
Typhoon provides a Terraform Module for defining a Kubernetes cluster on each supported operating system and platform.
Typhoon is available for [Fedora CoreOS](https://getfedora.org/coreos/).

Define a Kubernetes cluster by using the Terraform module for your chosen platform and operating system. Here's a minimal example:
```tf
module "yavin" {
source = "git::https://github.com/poseidon/typhoon//google-cloud/fedora-coreos/kubernetes?ref=v1.31.3"# Google Cloud
cluster_name = "yavin"
region = "us-central1"
dns_zone = "example.com"
dns_zone_name = "example-zone"# configuration
ssh_authorized_key = "ssh-ed25519 AAAAB3Nz..."# optional
worker_count = 2
worker_preemptible = true
}# Obtain cluster kubeconfig
resource "local_file" "kubeconfig-yavin" {
content = module.yavin.kubeconfig-admin
filename = "/home/user/.kube/configs/yavin-config"
file_permission = "0600"
}
```Initialize modules, plan the changes to be made, and apply the changes.
```sh
$ terraform init
$ terraform plan
Plan: 62 to add, 0 to change, 0 to destroy.
$ terraform apply
Apply complete! Resources: 62 added, 0 changed, 0 destroyed.
```In 4-8 minutes (varies by platform), the cluster will be ready. This Google Cloud example creates a `yavin.example.com` DNS record to resolve to a network load balancer across controller nodes.
```sh
$ export KUBECONFIG=/home/user/.kube/configs/yavin-config
$ kubectl get nodes
NAME ROLES STATUS AGE VERSION

yavin-worker-jrbf.c.example-com.internal Ready 5m v1.31.3
yavin-worker-mzdm.c.example-com.internal Ready 5m v1.31.3
```List the pods.

```## Non-Goals
Typhoon is strict about minimalism, maturity, and scope. These are not in scope:
* In-place Kubernetes Upgrades
* Adding every possible option
* Openstack or Mesos platforms## Help
Schedule a meeting via [Github Sponsors](https://github.com/sponsors/poseidon?frequency=one-time) to discuss your use case.
## Motivation
Typhoon powers the author's cloud and colocation clusters. The project has evolved through operational experience and Kubernetes changes. Typhoon is shared under a free license to allow others to use the work freely and contribute to its upkeep.
Typhoon addresses real world needs, which you may share. It is honest about limitations or areas that aren't mature yet. It avoids buzzword bingo and hype. It does not aim to be the one-solution-fits-all distro. An ecosystem of Kubernetes distributions is healthy.
## Social Contract
Typhoon is not a product, trial, or free-tier. Typhoon does not offer support, services, or charge money. And Typhoon is independent of operating system or platform vendors.
Typhoon clusters will contain only [free](https://www.debian.org/intro/free) components. Cluster components will not collect data on users without their permission.
## Sponsors
Poseidon's Github [Sponsors](https://github.com/sponsors/poseidon) support the infrastructure and operational costs of providing Typhoon.
