Typhoon is a minimal and free Kubernetes distribution.

Documentation
Usage
Define a Kubernetes cluster by using the Terraform module for your chosen platform and operating system. Here's a minimal example:
module "yavin" { source = "git::https://github.com/poseidon/typhoon//google-cloud/fedora-coreos/kubernetes?ref=v1.28.4"# 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.
$ 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.
$ 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 v1.28.4 yavin-worker-jrbf.c.example-com.internal <none> Ready 5m v1.28.4 yavin-worker-mzdm.c.example-com.internal <none> Ready 5m v1.28.4
List the pods.

Non-Goals
Typhoon is strict about minimalism, maturity, and scope. These are not in scope:
Help
Schedule a meeting via Github Sponsors 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 components. Cluster components will not collect data on users without their permission.
Sponsors
Poseidon's Github Sponsors support the infrastructure and operational costs of providing Typhoon.
