ARM64
Typhoon supports ARM64 Kubernetes clusters with ARM64 controller and worker nodes (full-cluster) or adding worker pools of ARM64 nodes to clusters with an x86/amd64 control plane for a hybdrid (mixed-arch) cluster.
Typhoon ARM64 clusters (full-cluster or mixed-arch) are available on:
- AWS with Fedora CoreOS or Flatcar Linux
- Azure with Flatcar Linux
Cluster
Create a cluster on AWS with ARM64 controller and worker nodes. Container workloads must be arm64 compatible and use arm64 (or multi-arch) container images.
=== "Fedora CoreOS Cluster (arm64)"
```tf
module "gravitas" {
source = "git::https://github.com/poseidon/typhoon//aws/fedora-coreos/kubernetes?ref=v1.27.4"
# AWS
cluster_name = "gravitas"
dns_zone = "aws.example.com"
dns_zone_id = "Z3PAABBCFAKEC0"
# configuration
ssh_authorized_key = "ssh-ed25519 AAAAB3Nz..."
# optional
arch = "arm64"
networking = "cilium"
worker_count = 2
worker_price = "0.0168"
controller_type = "t4g.small"
worker_type = "t4g.small"
}
```
=== "Flatcar Linux Cluster (arm64)"
```tf
module "gravitas" {
source = "git::https://github.com/poseidon/typhoon//aws/flatcar-linux/kubernetes?ref=v1.27.4"
# AWS
cluster_name = "gravitas"
dns_zone = "aws.example.com"
dns_zone_id = "Z3PAABBCFAKEC0"
# configuration
ssh_authorized_key = "ssh-ed25519 AAAAB3Nz..."
# optional
arch = "arm64"
networking = "cilium"
worker_count = 2
worker_price = "0.0168"
controller_type = "t4g.small"
worker_type = "t4g.small"
}
```
Verify the cluster has only arm64 (aarch64) nodes. For Flatcar Linux, describe nodes.
$ kubectl get nodes -o wide

Hybrid
Create a hybrid/mixed arch cluster by defining an AWS cluster. Then define a worker pool with ARM64 workers. Optional taints are added to aid in scheduling.
