# Typhoon <img align="right" src="https://storage.googleapis.com/poseidon/typhoon-logo.png">
|
|
|
|
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 clouds
|
|
|
|
Typhoon distributes upstream Kubernetes, architectural conventions, and cluster addons, much like a GNU/Linux distribution provides the Linux kernel and userspace components.
|
|
|
|
## Features <a href="https://www.cncf.io/certification/software-conformance/"><img align="right" src="https://storage.googleapis.com/poseidon/certified-kubernetes.png"></a>
|
|
|
|
* Kubernetes v1.13.5 (upstream, via [kubernetes-incubator/bootkube](https://github.com/kubernetes-incubator/bootkube))
|
|
* Single or multi-master, [Calico](https://www.projectcalico.org/) 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/)
|
|
* Advanced features like [worker pools](advanced/worker-pools/), [preemptible](cl/google-cloud/#preemption) workers, and [snippets](advanced/customization/#container-linux) customization
|
|
* Ready for Ingress, Prometheus, Grafana, CSI, or other [addons](addons/overview/)
|

|
## 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 |

|
## Example
|
|
|
|
Define a Kubernetes cluster by using the Terraform module for your chosen platform and operating system. Here's a minimal example.
|
|
|
|
```tf
|
|
module "google-cloud-yavin" {
|
|
source = "git::https://github.com/poseidon/typhoon//google-cloud/container-linux/kubernetes?ref=v1.13.5"
|
|
|
|
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.
|
|
|
|
```sh
|
|
$ 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 v1.13.5
|
|
yavin-worker-jrbf.c.example-com.internal node Ready 5m v1.13.5
|
|
yavin-worker-mzdm.c.example-com.internal node Ready 5m v1.13.5
|
|
```
|
|
|
|
List the pods.
|
|
|
|
```
|
|
$ kubectl get pods --all-namespaces

## 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](https://www.debian.org/intro/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](https://github.com/poseidon/typhoon/wiki/Donations) to show your appreciation.
