Typhoon 
Typhoon is a minimal and free Kubernetes distribution.
- Minimal, stable base Kubernetes distribution
- Declarative infrastructure and configuration
- Free (freedom and cost) and privacy-respecting
- Practical for labs, datacenters, and clouds
Typhoon distributes upstream Kubernetes, architectural conventions, and cluster addons, much like a GNU/Linux distribution provides the Linux kernel and userspace components.
Features 
- Kubernetes v1.14.2 (upstream, via kubernetes-incubator/bootkube)
- Single or multi-master, Calico or flannel networking
- On-cluster etcd with TLS, RBAC-enabled, network policy
- Advanced features like worker pools, preemptible workers, and snippets customization
- Ready for Ingress, Prometheus, Grafana, CSI, or other addons
Modules
Typhoon provides a Terraform Module for each supported operating system and platform. Container Linux is a mature and reliable choice. Also, Kinvolk's Flatcar Linux fork is selectable on AWS and bare-metal.
| Platform | Operating System | Terraform Module | Status |
|---|---|---|---|
| AWS | Container Linux | aws/container-linux/kubernetes | stable |
| Azure | Container Linux | azure/container-linux/kubernetes | alpha |
| Bare-Metal | Container Linux | bare-metal/container-linux/kubernetes | stable |
| Digital Ocean | Container Linux | digital-ocean/container-linux/kubernetes | beta |
| Google Cloud | Container Linux | google-cloud/container-linux/kubernetes | stable |
Fedora Atomic support is alpha and will evolve as Fedora Atomic is replaced by Fedora CoreOS.
| Platform | Operating System | Terraform Module | Status |
|---|---|---|---|
| AWS | Fedora Atomic | aws/fedora-atomic/kubernetes | deprecated |
| Bare-Metal | Fedora Atomic | bare-metal/fedora-atomic/kubernetes | deprecated |
| Digital Ocean | Fedora Atomic | digital-ocean/fedora-atomic/kubernetes | deprecated |
| Google Cloud | Fedora Atomic | google-cloud/fedora-atomic/kubernetes | deprecated |

Usage
Define a Kubernetes cluster by using the Terraform module for your chosen platform and operating system. Here's a minimal example:
module "google-cloud-yavin" {
source = "git::https://github.com/poseidon/typhoon//google-cloud/container-linux/kubernetes?ref=v1.14.2"
providers = {
google = "google.default"
local = "local.default"
null = "null.default"
template = "template.default"
tls = "tls.default"
}
# Google Cloud
cluster_name = "yavin"
region = "us-central1"
dns_zone = "example.com"
dns_zone_name = "example-zone"
# configuration
ssh_authorized_key = "ssh-rsa AAAAB3Nz..."
asset_dir = "/home/user/.secrets/clusters/yavin"
# optional
worker_count = 2
}
Initialize modules, plan the changes to be made, and apply the changes.
$ terraform init
$ terraform plan
Plan: 64 to add, 0 to change, 0 to destroy.
$ terraform apply
Apply complete! Resources: 64 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.
$ export KUBECONFIG=/home/user/.secrets/clusters/yavin/auth/kubeconfig
$ kubectl get nodes
NAME ROLES STATUS AGE VERSION
yavin-controller-0.c.example-com.internal controller,master Ready 6m v1.14.2

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

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. It is not run by a company, does not offer support or services, and does not accept or make any money. It is not associated with any operating system or platform vendor.
Typhoon clusters will contain only free components. Cluster components will not collect data on users without their permission.
Donations
Typhoon does not accept money donations. Instead, we encourage you to donate to one of these organizations to show your appreciation.
