|
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.
|
|
|
|

## Usage
|
|
|
|
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=v1.27.0"
|
|
|
|
# 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"
|
|
}
|
|
```
|
|
|
|
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-controller-0.c.example-com.internal <none> Ready 6m v1.27.0
|
|
yavin-worker-jrbf.c.example-com.internal <none> Ready 5m v1.27.0
|
|
yavin-worker-mzdm.c.example-com.internal <none> Ready 5m v1.27.0
|
|
```
|
|
|
|
List the pods.
|
|
|
|
```
|
|
$ kubectl get pods --all-namespaces
|
|
NAMESPACE NAME READY STATUS RESTARTS AGE

|
kube-system calico-node-1cs8z 2/2 Running 0 6m
|
|

|
|

## 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.
